Anatomical terminology, anatomical nomenclature, Terminologia Anatomica, vessels, artery, vein


This article is the fourth and last part of a series aimed at extending and correcting the anatomical nomenclature. Because of the rapid development of internet and the use of electronic formats in communication in anatomy, embryology, histology, medical education, and clinical medicine, an appropriate, precise, and concise anatomical nomenclature is required. Such tool enables to avoid any potential confusion and possible scientific/medical mistakes. The up-to-date official anatomical terminology, Terminologia Anatomica, is available longer than 20 years and needs to be refined and extended. The authors have collected and listed 210 terms and completed them with definitions and/or explanations. We aimed to start a discussion about their potential incorporation into the new revised version of the Terminologia Anatomica. This article is primarily focused on the vessels of the human body (arteries, veins, and lymphatic system).

This article is the fourth and last part of a series aimed at extending and correcting the anatomical nomenclature. It closes a set of contributions to extent and revise the technical norm for naming morphological structures of the human body in relation to the anatomical nomenclature of the nervous system and senses [1], locomotor system [2], and organs [3]. All the general statements and discussions concerning the history, grammar, and clinical relevance of the anatomical nomenclature and terminology are parts of our previous set of articles. We have also repetitively stressed the importance of anatomical nomenclature in enabling clear, unanimous, and unambiguous communication among specialists. All revised or newly proposed terms to be potentially incorporated into the only official valid version of the anatomical nomenclature called Terminologia Anatomica (TA) are summarized in these articles [1-15].

International Federation of Associations of Anatomists (IFAA) is the only organ responsible for worldwide valid official terminology in human anatomy, histology, and embryology. Concerning the anatomical nomenclature, its last version is quite old-fashioned as it was issued already 22 years ago, in 1998 [16], by not anymore existing Federative Committee on Anatomical Terminology (FCAT), which was in 2005 renamed to Federative International Committee on Anatomical Terminology (FICAT) and in 2009 replaced by Federative International Programme on Anatomical Terminology (FIPAT). Now, FIPAT prepares a new edition called Terminologia Anatomica 2, which is already available online as a draft not yet approved by IFAA and thus not official [17]. The anatomical terminology of vessels is also part of the Terminologia Histologica, published in 2008 [18], Terminologia Embryologica in 2013 [19] and its revision Terminologia Embryologica 2, issued in 2017 [20], and concerning the brain and sensory organs as a part of the Terminologia Neuroanatomica, published in 2017 [21].

The authors have gathered anatomical terms of vascular system absent in the Terminologia Anatomica that they have encountered during their scientific and educational work. Some terms listed here are mentioned and explained in classical textbooks and familiar to all anatomist and thus they are not completed with references. Other terms have been reviewed, refined, or proposed de novo for anatomical structures which were previously not well described and/or defined.

Terms presented in bold italics are newly created terms proposed for incorporation into the Terminologia Anatomica, terms presented in plain italics are already listed in the Terminologia Anatomica, terms within quotation marks are non-recommended or obsolete, terms in parentheses are eponyms, synonyms, or explanations, and terms marked with asterisks have been already stated in some of our previous works. In total, 210 terms are suggested for incorporation into the TA: 22 concerning general terms in Systema cardiovasculare, 47 items in heart, 56 arteries, 51 veins, and 34 structures in Systema lymphaticum. The list of Latin terms compared to their English equivalents is presented in Table 1.

TABLE 1: List of Latin terms with their English equivalents


  • Fasciculus vasonervosus* (neurovascular bundle) is a bundle of a nerve and one or more vessels. The peripheral or cranial nerve is accompanied by an artery and one or two veins, or, if located in a superficial compartment, a cutaneous nerve is accompanied by a superficial vein. The bundle is encompassed in a fibrous sheath and consists of homonymous or heteronymous structures (nervus ulnaris – vasa ulnaria; nervus fibularis profundusvasa tibialia anteriora) [11].

  • Angiosoma* is an anatomical unit of tissue composed of skin, subcutaneous tissue, fascia, muscle, and bone which is nourished by a specific artery and drained by specific veins [22]. The whole human body consists of 40 angiosomes [23]. Arteriosoma is such anatomical unit supplied by a specific artery [24] and venosoma* is the same unit drained by a specific vein. In case the extent of the venous drainage is different from arterial supply of the angiosoma, the anatomical unit is termed phlebosoma* [25]. The anatomical unit drained by superficial lymphatic vessels is then termed lymphosoma [13,26].

  • Some organs (lungs, liver) feature two types of circulation – nutritive and functional. It is necessary to denominate them also in Latin and there exist terms: The vasa privata for the nutritive circulation and the vasa publica for the functional one [27].

  • Vincula arteriarum are thin fibrous bands fixating arteries (with accompanying vessels) to adjacent tissue, e.g. vasa tibialia anteriora, hidden in fibrous sheath, to the membrana interossea cruris.

  • General term for the venous valve valvula venosa – is not precise as a classical venous valve comprises two swallow-nest-shaped cusps, called valvulae, and that is why the term has to be redressed to the valva venosa consisting of two valvulae. These valvules are attached to the venous wall by a firm margo affixus (margo parietalis) and their free concave margo liber protrudes into the lumen of the vein. The blood current travels on the facies luminalis valvulae, when it is stopped and turns back, the margo liber is deflected from the wall toward the opposite valvule, and the lumen is closed. A space formed then by the facies parietalis valvulae is termed the sinus valvulae. A junction between the margo affixus and the margo liber is denominated the cornu valvulae and the slightly elevated parts between adjacent ends of the margines affixi are termed the commissurae valvae as they connect the two valvules. The body of the valvule is called the cuspis valvulae and it is thickened at the margo affixus in the double-horseshoe-shaped agger valvulae (clinically frequently called “tuberculum” or “limbus”) [28].

  • Vasa gonadalia is a general term which can be used either during the early development when the gender of the embryo is still indifferent or if referred to the vasa testicularia in male or to the vasa ovarica in female unspecificly, i.e. when general features of these vessels are discussed, not related to the gender.

  • Vasa cruralia is a general term for the principal trunks of the leg (vasa tibialia anteriora, vasa tibialia posteriora, and vasa fibularia) and can be used when they are considered as general vessels coursing within the leg and supplying the leg and foot.


  • Crux cordis is an area on the facies posterior cordis where the sulcus coronarius and the sulcus interventricularis posterior meet.

  • In pathology, the division of the heart atrium into the corpus atrii and the vestibulum atrii is used. Both parts of the atrium are smooth due to the absence of the musculi pectinati. On the right side, musculi pectinati are overlapping from the auricle onto the free atrial wall and they divide the atrium dextrum into the vestibulum atrii and the corpus atrii. On the left side, the musculi pectinati are reduced to the auricle only and thus, the vestibulum atrii and the corpus atrii are in direct continuation. The corpus atrii sinistri receives the venae pulmonales (comprises the ostia venarum pulmonalium) and the vestibulum atrii sinistri is a smooth part of the atrium below this level.

  • Cuspis valvae mitralis/tricuspidalis features three parts: The apex, the margo, and the basis.

  • Each leaflet (cuspis) of a cuspidal valve (valva mitralis et tricuspidalis) is separated from the other(s) by commissures: The commissura anterolateralis and the commissura posteromedialis are present in the valva mitralis between its two leaflets and they are denominated according to their location; the commissura anteroposterior the commissura posteroseptalis and the commissura anteroseptalis are present in the valva tricuspidalis between its three leaflets and they are denominated according to which leaflets they connect.

  • Trigonum nodi atrioventricularis (of Koch) is a triangle in the right atrium and is defined by three angles: The ostium sinus coronarii, the tendo valvulae venae cavae inferioris (of Todaro) and the cuspis posterior valvae tricuspidalis (or more precisely its commissura anteroseptalis). Underneath its surface, the nodus atrioventricularis is situated.

  • Crus sinistrum fasciculi atrioventricularis (of Tawara) terminates by a bifurcation into the crus anterosinistrum and crus posterosinistrum.

  • Skeleton cordis is a general term for the fibrous scaffold supporting the valves and muscle fibers and electrically isolating the atria from the ventricles. It comprises four anuli, two triangles, three ligaments, pars membranacea septi, and some other parts [29].

    • Anulus aorticus et anulus trunci pulmonalis are integral parts of the skeleton cordis, encircling the corresponding ostia, and forming scaffold for corresponding valves.

    • Fila coronaria (“subvalvar collar”; “subvalvar membrane”) are fibrous subendocardial cords, extensions of the trigona fibrosa, forming approximately 75% of the anuli fibrosi of the heart skeleton (the rest is only a less distinct sheet of fibroelastic tissue).

    • Pars membranacea septi is a small fibrous part of the skeleton cordis which contributes to the separation of the right and left atria (subpars interatrialis partis membranacae septi) and of the right atrium and left ventricle (subpars atrioventricularis partis membranaceae septi). Due to its complex structure, its subparts deserve their own denominations.

    • Septum intervalvulare ventriculi dextri (“subaortic curtain”) is a part of the fibrous skeleton cordis having the shape of a sheet that spans the gap between the fibrous arches supporting the valvula semilunaris sinistra et dextra valvae aorticae. It passes caudally within the wall of the right atrium and blends with the fibrous core of the cuspis anterior valvae mitralis.

    • Continuum aortomitrale (“fibrous aortic-mitral continuity”) is a fibrous area between the trigonum fibrosum dextrum et sinistrum (laterally), the anulus fibrosus sinister (ventrally), and the anulus aorticus (dorsally) and is important in aortic valvular replacement surgery.

    • Trigona subcommissuralia (interleaflets triangles) are located between the valvulae semilunares valvae aortae and their commissures and should be left free in aortal valvuloplasty.

    • Tendo coni is an inconsistent fibrous band at the contact point of the beginning of the truncus pulmonalis and aorta ascendens, extending somewhere between the commissura sinistrodextra valvae aortae and the pulmonary valvar sinuses.

    • Tendo infundibuli is an inconstant fibrous band within the crista supraventricularis, arising at the level of the pars membranacea septi interventricularis and extending cranially to connect with the posterior surface of the conus arteriosus (“infundibulum; pars glabra”) at the base of the truncus pulmonalis.

    • Commissurae valvularum semilunarium are three in each outflow valve and should be distinguished according to their position. Valva aortae contains the commissura sinistrodextra, commissura posterosinistra et commissura posterodextra; valva trunci pulmonalis contains the commissura sinistrodextra, commissura anterosinistra et commissura anterodextra.

  • Isthmus cavotricuspidalis is a fibrous tissue in the lower part of the right atrium, located between the vena cava inferior and the valva tricuspidalis.

  • Plica ventriculoinfundibularis is a fine muscular bundle interposed between the leaflets of an atrioventricular (cuspidal) and a ventriculoarterial (semilunar) valve, i.e. it separates the inlet (inflow part) of the ventricle from its outlet (outflow part). The plica is a relatively fine sheet of a muscle that is folded back on itself [30].

  • Junctio sinutubularis is a narrow zone (2-3.5 mm high) of the aorta ascendens above the bulbus aortae where the normal tubular configuration of the aorta is attained.

  • Nodus sinuatrialis can be subdivided into the caput and the cauda.

  • All the vascular openings in the heart cavities are termed ostia except the smallest ones, foramina venarum minimarum. The term foramen is in heart related to the developmental structures (foramen ovale, foramen primum, foramen secundum, and foramen interventriculare) and that is why the term for openings of the venae cardiacae minimae should be changed to the ostia venarum (cardiacarum) minimarum. Similarly, terms for innominate openings of the venae ventriculi dextri anteriores should be created – ostia venarum ventriculi dextri anteriorum.

  • Ostium arteriae coronariae is the opening of a coronary artery located in the lateral wall of the sinus aortae (of Valsalva).

  • Ramus diagonalis is a clinically used term for the ramus lateralis, branch from the ramus interventricularis anterior. Its course is oblique (or diagonal) across the ventral surface of the left ventricle toward the apex cordis and due to the anatomical position and the preference by clinicians, the term ramus diagonalis should be preferred. Sometimes, it can be doubled or tripled (ramus diagonalis primus, secundus et tertius).

  • Ramus posterolateralis sinister is a variant largest ramus posterior ventriculi sinistri (a terminal branch of the ramus circumflexus arteriae coronariae sinistrae), being present in the case of dominance of the arteria coronaria sinistra (in that case a bypass can be applied to the stenotic ramus posterolateralis sinister).

  • Valva terminalis venae cardiacae magnae (of Vieussens) is a nearly constant (75%) ostial valve at the transition between the vena cardiaca magna and the sinus coronarius, located at the margo sinister cordis.

  • Cavitas pericardiaca is a serous cavity between the lamina parietalis pericardii and the lamina visceralis pericardii, containing a small amount of the liquor pericardii.

  • Porta arteriarum (obsolete term “vagina serosa arteriarum”) is a transition of the lamina parietalis pericardii into the lamina visceralis pericardii, encompassing both the aorta ascendens and the truncus pulmonalis in the extent of 2 cm. Porta venarum (obsolete term “vagina serosa venarum”) is a similar transition on the venae cavae and the venae pulmonales, located caudally to the former in the posterior wall of the pericardium.


  • Arteriae ciliares posteriores longae are two in each eyeball and can be distinguished as the medial arteria ciliaris posterior longa nasalis and the lateral arteria ciliaris posterior longa temporalis.

  • Rami trabeculares are branches from the ramus anterior arteriae hypophysialis superioris, descending in front of the infundibulum and terminating in a large arterial stem, the arteria trabecularis, along the pars tuberalis hypophysis.

  • Arcus labiorum superior is an arterial anastomosis of the arteria labialis superior dextra et sinistra located in the mass of the musculus orbicularis oris of the upper lip. Similarly, arcus labiorum inferior is an arterial anastomosis of the arteria labialis inferior dextra et sinistra in the lower lip.

  • Arteria subclavia dextra aberrans (ASDA)* is a clinically relevant but rather rare variant (approximately 1% of cases) of the arteria subclavia, ramifying as the very last branch from the arcus aortae, left (distally) to the origin of the arteria subclavia sinistra, and crossing the midline to the right side. It may run in front of the trachea as the ASDA pretrachealis (5% of all ASDA), between the trachea and the esophagus as the ASDA retrotrachealis (15%) and between the esophagus and the vertebral column as the ASDA retrooesophgea (retro-esophageal right subclavian artery/RRESA/), found in about 80% of all ASDA). In the two latter cases, it could compress the esophagus and may cause problems with swallowing termed dysphagia lusoria that is why in the case of present clinical symptoms, the variant artery used to be called the “arteria lusoria” [11,31].

  • Arteria pyramidalis is a variant branch from the distal part of the arteria thyroidea superior, just before its bifurcation into its ramus anterior et posterior, supplying the lobus pyramidalis glandulae thyroideae, when present (40% of cases) [32].

  • Arteria supraclavicularis is a smaller branch either from the arteria transversa cervicis directly [10] or from its ramus superficialis, coursing within the regio cervicalis lateralis and supplying the fascia and the skin above and below the clavicle.

  • The variations of the main upper limb arterial trunks occur in about 20% of cases. They comprise trunks with superficial course, high origins of the forearm trunks, variant vessels or combinations (arteria brachialis superficialis, arteria brachialis accessoria, arteria brachioradialis superficialis, arteria brachioulnaris superficialis, arteria brachioulnoradialis superficialis, arteria brachiomediana superficialis, arteria comitans nervi mediani manus et antebrachii*, etc.) [12,33-42].

  • Arteria cubitalis inferior (obsolete terms “arteria antebrachialis volaris superficialis; arteria antebrachialis mediana”) is the first branch of the arteria radialis and is the largest perforating artery in the forearm. It passes superficially between the musculus brachioradialis and musculus pronator teres and its branches spread across the fascia antebrachii along the medial aspect of the vena cephalica toward the processus styloideus radii. The area of the skin fed by this artery is considered to be the largest nourished by a single cutaneous arterial perforator [43-44].

  • Arteria interossea anterior bifurcates into two terminal branches: The ramus palmaris supplying the musculus pronator quadratus, running deep underneath, and joining the rete carpale palmare; and ramus dorsalis penetrating the membrana interossea anterior to anastomose with the arteria interossea posterior which then joins the rete carpale dorsale.

  • Ramus carpalis dorsalis arteriae ulnaris (obsolete term “dorsal ulnar artery”) bifurcates into the ramus ascendens et descendens, the latter anastomosing with the ramus profundus arteriae ulnaris [45].

  • Rete carpale palmare is a small anastomotic network on the anterior aspect of the wrist, fed by the ramus carpalis palmaris arteriae radialis, ramus carpalis palmaris arteriae ulnaris, and ramus palmaris arteriae interosseae anterioris.

  • The thumb is fed by four arteries, two dorsal and two palmar, coursing along the nerves in neurovascular bundles. The palmar arteries are larger and nearly constant, the dorsal are smaller and rather variable. Their terminology is not coined and Miletin et al. proposed the descriptive terms arteria digitalis ulnopalmaris pollicis et arteria digitalis radiopalmaris pollicis for the palmar arteries and arteria digitalis ulnodorsalis pollicis et arteria digitalis radiodorsalis pollicis for the palmar arteries. Based on the statistics, the current terminology using the term arteria princeps pollicis is not specific enough as the word princeps describes the principal (largest) source artery which rather varies for the thumb – the largest caliber features the arteria metacarpalis palmaris prima – that is why the term “arteria princeps pollicis” should be abandoned and removed from the TA [46].

  • An inconstant artery branches from the arteria radialis at the dorsum of the hand just before it enters the space between the heads of the musculus interosseus dorsalis primus. This artery then runs distally on the dorsal surface of the muscle and at the distal margin of the first web space, it turns back into the palm and forms an anastomosis with the arcus palmaris superficialis. Miletin et al. reported its incidence (12%) and proposed the term ramus superficialis dorsalis arteriae radialis [47].

  • Arteria spinalis anterior is an unpaired vessel originating as a confluence of a short paired innominate artery branching from the arteria vertebralis. These short transverse vessels can be denominated as the ramus vertebrospinalis dexter et sinister.

  • Arteria medullaris segmentalis is a term of the TA replacing the clinically used arteria radiculospinalis; another vessel, arteria radiculopialis, is important in clinical medicine and gives off the pial vasocoronae, encompassing the spinal cord horizontally and emanating the rami perforantes to supply the white matter; finally, the arteria spinalis anterior branches off the arteriae sulcocommissurales into the fissura mediana anterior to supply the grey matter [48,49].

  • Arteria radicularis magna (listed in TNA [21]) or the “artery of Adamkiewicz” is the largest and clinically the most important ramus spinalis arteriae intercostalis posterioris and thus it should be termed the ramus spinalis magnus (arteriae intercostalis posterioris).

  • The variations of the truncus coeliacus are quite frequent and its incomplete formation appears in 8% of cases as truncus gastrosplenicus (3.46%), truncus hepatosplenicus (3.88%), and truncus hepatogastricus (0.24%) [50].

  • Arteria splenica bifurcates into the ramus anterior et posterior arteriae splenicae, which then further ramify into the segmental rami splenici.

  • The mighty vasculature of the intestine consists of source arteries (and draining veins), their main macroscopic branches (and tributaries), fine vessels supplying the intestinal wall called arteriae et venae intestinales rectae* and then by intramural plexuses. Their terminology should match the nervous counterparts, i.e. plexus vasculosus myentericus located between the stratum longitudinale and stratum circulare tunicae muscularis and plexus vasculosus submucosus located with the submucosa [3,51].

  • Rami retroperitoneales anteriores* are direct fine branches from the aorta abdominalis, the arteria renalis and the arteria renalis accessoria, the arteria testicularis or the arteria ovarica, and the arteria iliaca communis. They feed the adjacent lymph nodes (nodi lymphatici lumbales et iliaci communes), ureter, peritoneum, loose connective tissue around the aorta abdominalis and the vena cava inferior, autonomic nervous plexuses and their ganglia and the vascular wall of both the aorta abdominalis and vena cava inferior forming their vasa vasorum. These rami are followed by homonymous fine veins (venae retroperitoneales anteriores), emptying into the ventral aspect of the vena cava inferior and its tributaries [52,53].

  • Arteriae sacrales laterales are usually two branches (arteria sacralis lateralis superior et inferior) emanating from the divisio posterior arteriae iliacae internae, descending and bifurcating into the corresponding rami spinales to enter four foramina sacralia anteriora ossis sacri to supply the bone, contents of the canalis sacralis and adjacent part of the deep back muscles.

  • The arteria obturatoria is usually a branch from the arteria iliaca interna, but sometimes it can ramify from the arteria epigastrica inferior. In such case, it should be termed arteria obturatoria aberrans. If there are two arteries present, one originating from the arteria iliaca interna and the other from the arteria epigastrica inferior, they should be called as the arteria obturatoria propria and arteria obturatoria acesssoria aberrans, respectively. Similar approach can be applied to the veins: Vena obturatoria aberrans and vena obturatoria accessoria aberrans.

  • In angiology and vascular surgery, the proximal segment of the vasa femoralia, from the arbitrary beginning under the ligamentum inguinale within the lacuna vasorum to the branching of the arteria profunda femoris (and termination of the vena profunda femoris, respectively), are termed the arteria femoralis communis* and the vena femoralis communis*. The distal segment is then in vascular surgery termed “arteria et vena femoralis superficialis,” but phlebologists do not accept this terminology as they consider superficial veins only those coursing above the layer of muscular fascia, e.g. venae saphenae [4-6,13,54], which can be agreed to.

  • Three branches of the arteria profunda femoris, supplying the posterior and medial groups of the thigh muscles are called the arteriae perforantes and classified using numbers according to the level of their origin as the arteria perforans prima*, arteria perforans secunda*, and arteria perforans tertia*. Their accompanying veins are denominated in a bit different way as the venae comitantes arteriarum perforantium* due to the fact that the term venae perforantes is reserved for the veins interconnecting the superficial and deep venous systems [9,13,15,54].

  • Truncus tibiofibularis* is the short proximal segment of the arteria tibialis posterior, between its origin from the arteria poplitea to the branching point of the arteria fibularis [13].

  • Arteriae tarsales mediales should be specified as the arteria tarsalis medialis proximalis* and the arteria tarsalis medialis distalis*; arteriae tarsales laterales as the arteria tarsalis lateralis proximalis* and the arteria tarsalis lateralis* [13].

  • Arteria sinus tarsi medialis (“arteria canalis tarsi; arteria of Salvi”) and arteria sinus tarsi lateralis (“arteria anastomotica tarsi; ramus anastomicus tarsi; perforating vessel of sinus tarsi”) are important feeding arteries of the talus with variable origin from the arteria tibialis posterior (or less often from the arteria plantaris medialis), and from the arteria dorsalis pedis (or less often from the arteria tarsalis lateralis proximalis or arteria malleolaris lateralis anterior), respectively [13,55].


  • Vena retromandibularis terminates in a specific way by a bifurcation (similarly to the vena portae hepatis and the vena dorsalis penis/clitoridis profunda) into the ramus anterior draining into the vena facialis and the ramus posterior forming the vena jugularis externa by the confluence with the vena auricularis posterior.

  • Vena facialis communis is a short terminal segment of the vena facialis after it is joined by the ramus anterior venae retromandibularis; then, it usually drains into the vena jugularis interna.

  • Some tributaries of the plexus pterygoideus are missing in the TA: The vena sphenopalatina, the venae palatinae, the vena infraorbitalis, and the plexus cavernosi concharum, especially in the area of the concha nasalis inferior.

  • Zona bilaminaris (of Rees) [56], also called “retroarticular/retrodiscal plastic pad/cushion (of Zenker)” [57] or “trilaminar zone (of Smeele)” [58], is the posterior continuation of the discus articularis articulationis temporomandibularis, consisting of the stratum superius (fibroelastic loose network of elastic and collagen fibers, adipose tissue and fine vessels, attached to the posterior margin of the fossa mandibularis ossis temporalis), stratum inferius (stiff/non-elastic network of collagen fibers, attached to the caput mandibulae), and in between interposed genu vasculosum (adipose tissue, connective tissue and mainly a venous plexus, a dorsal extension of the plexus pterygoideus), which serves as shock-absorber during the joint movements.

  • Arcus venosus xiphoideus is a transverse venous arch (present in approximately 80%) connecting the venae thoracicae internae dextrae et sinistrae across the midline, located ventral to the symphysis xiphosternalis [59].

  • Vena incisurae scapulae is a variable vein (58%), originating on the facies costalis scapulae, below the incisura scapulae, either from a vein accompanying the nutrient artery of the scapula and/or veins located beneath the fascia of the musculus subscapularis. It passes through the incisura scapulae and drains into the vena suprascapularis immediately after passing the notch [60,61].

  • Vena perforans cubitalis* (of Gracz) is the thickest perforating vein of the upper limb, located in the fossa cubitalis, usually connecting the vena mediana cubiti and the venae radiales and present in 100% of cases [12,62].

  • Truncus splenomesentericus is the last segment of the vena splenica, between its confluence with the vena mesenterica inferior (present in approximately 60-70% of cases) and the beginning of the vena portae hepatis [63].

  • Truncus gastropancreatocolicus (of Henle) is a short venous trunk, formed usually by the confluence of the vena gastroomentalis dextra, the vena pancreaticodudenalis superior anterior, and the vena colica dextra superior, draining into the vena mesenterica superior and located behind the caput pancreatis. It is present in 87% of cases [64].

  • Vena azygos originates usually by the confluens of the vena lumbalis ascendens dextra and the vena subcostalis dextra and immediately receives the variant vena azygos lumbalis dextra, branching from the posterior aspect of the vena cava inferior at the level of the opening of the vena lumbalis secunda (often a common trunk with the vena lumbalis secunda dextra or the vena renalis dextra) and present in 34% of cases. Vena hemiazygos receives a corresponding contralateral variant vessel – vena azygos lumbalis sinistra – branching from the posterior aspect of the vena renalis sinistra and present in 28% of cases [65]. Vena renalis sinistra features rather frequently (64% of cases) a communicating vein dorsally into the retroperitoneal tissue, either the vena azygos lumbalis sinistra draining into the vena hemiazygos or the vena communicans lumbalis emptying into the upper venae lumbales or into the vena lumbalis ascendens sinistra (64% of cases) [66,67].

  • Vena cremasterica is a gentle vein accompanying the arteria cremasterica in male and draining into the vena epigastrica inferior. Vena ligamenti teretis uteri is a gentle vein accompanying the homonymous artery in female [8].

  • Plexus pudendus* (of Santorini) is a small pelvic venous plexus located within the lower part of the spatium retropubicum (of Retzius) behind the inferior part of the symphysis pubica and in front of the inferior part of the urinary bladder and on the anterior and inferolateral surfaces of the prostate [8,13,54].

  • Vena portae hepatis is the only vessel with the non-concordant adjective “portae” and thus the specifying word “hepatis” can be omitted and the term for the main vessel of the liver can be shortened to vena portae.

  • Under pathological condition called the portal hypertension, veno-venous bypasses (shunts) open to relieve hypertension in the system of the vena portae. These are enlarged naturally formed veno-venous anastomoses in specific locations and they deserve to be officially termed as the anastomoses portocavales. They comprise the following major routes:

    • Anastomosis portocavalis gastrooesophagea (submucosa et adventitialis) between tributaries of the vena gastrica sinistra and the venae oesophageae including both the submucous and adventitial levels, sometimes presenting as esophageal and paraesophageal varices;

    • Anastomosis portocavalis rectalis (submucosa et adventitialis) between tributaries of the vena rectalis superior and the venae rectales mediae et inferiores including both the submucous and adventitial levels, the former sometimes presenting as internal hemorrhoids;

    • Anastomosis portocavalis subcutanea between the venae paraumbilicales (of Sappey) and tributaries of the venae epigastricae superficiales et venae thoracoepigastricae of both sides, presenting rather more rarely as “caput Medusae;”

    • Anastomosis portocavalis muscularis between the venae paraumbilicales (of Sappey) and tributaries of the venae epigastricae inferiores et superiores of both sides within the musculus rectus abdominis;

    • Anastomosis portocavalis preperitonealis (veins of Burrow) between the venae paraumbilicales (of Sappey) and tributaries of the plexus venosus vesicalis running in the midline along the ligamentum umbilicale medianum;

    • Anastomosis portocavalis retroperitonealis (veins of Retzius) between veins of the spleen and veins within the mesenterium and/or the mesocola, and the retroperitoneal veins and veins of the posterior abdominal wall (tributaries to the venae suprarenales, renales, tesiculares/ovaricae, lumbales, phrenicae inferiores et iliolumbales);

    • Anastomosis portocavalis hepatica between veins of the hepatic capsule and veins of the diaphragm in the extent of the area nuda hepatis.

  • Similarly to the portocaval anastomoses, under pathological condition with obturated vena cava superior or vena cava inferior, veno-venous bypasses (shunts) open to relieve the hypertension in the system of one of the venae cavae, termed the anastomoses cavocavales, which can be classified into the following groups:

    • Anastomosis cavocavalis subcutanea between tributaries of the venae epigastricae superficiales and those of the venae thoracoepigastricae within the subcutaneous layer of the anterolateral trunk wall;

    • Anastomosis cavocavalis muscularis between tributaries of the venae epigastricae inferiores and those of the venae epigastricae superiores within the musculus rectus abdominis;

    • Anastomosis cavocavalis retroperitonealis between tributaries of the venae lumbales and those of the venae lumbales ascendentes draining into the vena azygos and vena hemiazygos;

    • Anastomosis cavocavalis vertebralis between tributaries of the plexus venosi vertebrales (externi et interni) (plexus of Batson) extending along the columna vertebralis and within the canalis vertebralis.

  • Many new terms have been added concerning the lower limb veins, mainly concerning the superficial and perforating veins interconnecting the superficial and deep venous systems (venae perforantes). Among others, it is necessary to emphasize the following:

    • The termination of the vena saphena magna into the vena femoralis communis is called the junctio saphenofemoralis* and it is an integral part of the confluens venosus subinguinalis* (“crosse; bulbus; venous star of Paturet”), bordered by two valves of the vena saphena magna: The valva terminalis* (situated 1-2 mm distal to the junctio saphenofemoralis) and the valva preterminalis* (located 3-5 cm distally). This confluence receives the centripetal segments of the smaller venous tributaries: Vena epigastrica superficialis, vena circumflexa ilium superficialis, vena pudenda externa superficialis, vena saphena magna accessoria anterior et posterior, and vena circumflexa femoris anterior. Similarly, the term junctio saphenopoplitea* is applied to the termination of the vena saphena parva into the vena poplitea [9,13,54].

    • Extensio proximalis/cranialis venae saphenae parvae* (“vena femoropoplitea of Hyrtl;” “extensio cranialis venae saphenae parvae”) is a proximal continuation of the vena saphena parva. It ascends from the fossa poplitea on the posterior aspect of the thigh and terminates in more variants: It can submerge as the vena perforans femoris posterior/posterolateralis and drain into the vena profunda femoris; it can terminate in the muscular or subcutaneous venous plexus; it can continue as the vena intersaphena femoris* (of Giacomini) and drain into the vena saphena magna or its tributaries; or rarely, it can ascend as high as the gluteal region and empty into the venae gluteae inferiores. The extensio proximalis/cranialis is present in approximately 95% of cases [6,13,68,69].

    • Venae perforantes of the lower limb are numerous communications between the superficial and deep systems. Their extensive nomenclature has been proposed in 2005 and explained in detail by our team in 2019. The major impact consists in the rule that eponyms should be replaced with systemic terminology, e.g. first Cockett’s perforator with the vena perforans cruris tibialis posterior inferior* [15,70].


Generally, the term “lymphoid” meaning from the linguistic point of view precisely “similar to lymph” (“eidos” is a Greek term for the form) should be abandoned and instead the term “lymphatic” should be preferred in all terms related to the lymph, i.e. also in the denomination of the whole chapter: Systema lymphaticum.

  • Spleen can be divided into segments separated by avascular planes; constant are polar segments: Segmentum polare anterius et polare posterius, and variable is/are central segment(s): Segmentum interpositum / segmenta interposita.

  • Crenae splenis are deep clefts or notches (reaching some 2-3 cm in depth) located predominantly on the margo superior splenis (former “margo crenatus”) and facies diaphragmatica splenis [71].

  • Margo intermedius (splenis) is a ridge separating the spleen surface for the kidney and that for the stomach.

  • Nodus lymphaticus arcus venae azygoi is a lymph node from the group of the nodi lymphatici bronchopulmonales situated in the concavity of the arcus venae azygoi, the terminal segment of the vena azygos turning above the right lung hilum. It has to be stressed that the genitive of the Greek word azygos is azygoi.

  • Confluens lymphaticus abdominalis describes the very variable confluens of lymphatic trunci lumbales et intestinales, sometimes forming the cisterna chyli, located retroperitoneally approximately at the level of the first or second lumbar vertebra.

  • Lymph nodes draining the small and large intestine are arranged in groups which can be classified into three or four rows/levels, respectively. The small intestine lymph nodes comprise: Nodi lymphatici juxtaintestinales located close to the intestinal wall, nodi lymphatici mesenterici superiores intermedii located along the jejunal and ileal vessels, and nodi lymphatici mesenterici superiores centrales situated around the radix mesenterii along the trunk of the arteria mesenterica superior. The large intestine lymph nodes consist of four rows/levels: Nodi lymphatici epicolici stuck closely to the intestinal wall, nodi lymphatici paracolici located along the arteria marginalis coli (of Drummond), nodi lymphatici mesenterici inferiores intermedii located along the colic vessels (and classified in detail according to certain vessels: Nodi ileocolici, appendiculares, colici dextri, colici medii, colici sinistri, sigmoidei, et rectales superiores), and finally nodi lymphatici mesenterici inferiores centrales situated along the trunk of the arteria mesenterica inferior.

  • The lymphatic trunks of the limb (also known as “collectors”) can be divided into the superficial and deep, the former running independently on the superficial veins, and the latter extending in intimate relation to the deep vascular bundles. The term “lymphaticus” should be preferred to its grammatically incorrect synonym “lymphoideus” – see above [4,10].

  • Three main superficial lymphatic trunks of the upper limb constitute from the plexus lymphaticus palmaris* on the palmar aspect of the digits and hand: Truncus lymphaticus lateralis membri superioris* travels on the lateral side of the forearm and arm and empties into the nodi lymphatici axillares or directly into the plexus lymphaticus axillaris and nodi lymphatici cervicales lateralis profundi; truncus lymphaticus medialis membri superioris* courses on the medial side of the forearm and arm and empties into the nodi lymphatici axillares; and truncus lymphaticus anterior membri superioris* runs on the ventral side of the forearm and empties into one of the former trunks [12].

  • Three main superficial lymphatic trunks of the upper limb constitute from the plexus lymphaticus plantaris* on the inferior aspect of the toes and sole: Truncus lymphaticus medialis membri inferioris* ascends in front of the malleolus medialis on the ventromedial aspect of the leg dividing into the fasciculus medialis* (traveling medially to the condylus medialis femoris) and the fasciculus lateralis* and drains into the nodi lymphatici inguinales superficiales; truncus lymphaticus lateralis membri inferioris* courses on the lateral aspect of the leg and usually drains into the nodi lymphatici inguinales superficiales; and truncus lymphaticus posterior membri inferioris* runs on the posterior aspect of the leg and drains into the nodi lymphatici poplitei profundi [13].

  • The deep lymphatic trunks are termed according to the blood vessel they accompany: Truncus ulnaris*, truncus radialis*, truncus interosseus anterior et posterior*, and truncus brachialis*; truncus tibialis posterior et anterior*, truncus fibularis*, truncus popliteus*, and truncus femoralis*. In the pelvis, the situation is more complicated, see [13].


Some anatomically and/clinically very important terms have been already mentioned in our previous articles, but we felt inevitable to remind readers of them [6,8,9,11-13,15]. If we check the anatomical terminology in current journals, monographs, and textbook, there are still many terms found to be obsolete, incorrect, or even eponymic although the last revision of the anatomical nomenclature – Terminologia Anatomica (TA) – has been issued more than 20 years ago and eponyms have been banned from the anatomical nomenclature already in the Parisiensia Nomina Anatomica (PNA) in 1955 [16,72-76].

If we check the new proposal of Terminologia Anatomica 2 (TA 2), posted online [17] as a not yet approved version (the approval is planned at the next IFAA meeting in Istanbul in 2022), there are not many changes concerning the vessels, but there are some substantial changes concerning the heart which should be thoroughly reviewed and considered if they are appropriate and if they have a chance to be accepted by clinicians [e.g., change of the sulcus interventricularis posterior (including the ramus interventricularis posterior) to “sulcus interventricularis inferior” (and “ramus interventricularis inferior”)].

The main task of every anatomist and all anatomical societies, which continues and never stops, is to cultivate, clean, and revise the anatomical nomenclature not only in the anatomical field, education, journals, and textbooks but above all among clinicians, physicians, secondary school teachers, as well as lay public not only in English and Latin but also in individual languages.
