| venae hepaticae dextrae | Veins draining much of the right lobe of the liver (posterior segments [VI & VII] and part of the inferior anterior segment [V]) which merge to form a single or sometimes double trunk, draining into the right side of the suprahepatic portion of the inferior vena cava (between the superior surface of the liver and the diaphragm); when single, it is the largest vein of the liver. Synonym: venae hepaticae dextrae. (05 Mar 2000) |
|---|---|
| venae hepaticae mediae | Veins draining the central portion of the liver (the superior anterior segment [VIII] and the left side of the inferior anterior segment [V] of the right lobe and the medial segment [IV] of the left lobe) which join to form a trunk that merges with that of the left hepatic veins about 90% of the time prior to entering the left side of the inferior vena cava. Synonym: venae hepaticae mediae. (05 Mar 2000) |
| venae hepaticae sinistrae | Veins draining the lateral segments [II & III] of the left lobe of the liver which join to form a single or paired trunk of variable size which usually (90% of the time) merges with that formed by the middle hepatic veins prior to entering the terminal portion of the superior vena cava. Synonym: venae hepaticae sinistrae. (05 Mar 2000) |
| venae insulares | Veins draining the cortex of the insula, tributaries to the deep middle cerebral vein. Synonym: insular veins. (05 Mar 2000) |

| venae intercostales anteriores | Tributaries to the musculophrenic or internal thoracic veins from the anterior portions of intercostal spaces. Synonym: venae intercostales anteriores. (05 Mar 2000) |
| venae intercostales posteriores | Veins draining the intercostal spaces posteriorly; those of the first 1-C space drain into the brachiocephalic veins; from spaces 2-3 they drain into right and left superior intercostal veins; from the fourth to the eleventh spaces on the right they are tributaries of the azygos vein; on the left they empty into either the hemiazygos or accessory hemiazygos veins. Synonym: venae intercostales posteriores. (05 Mar 2000) |
| venae interlobulares hepatis | The terminal branches of the portal vein that course in the portal canals between the conceptual liver lobules and empty into the liver sinusoids. Synonym: venae interlobulares hepatis. (05 Mar 2000) |
| venae jejunales et ilei | The veins that drain the jejunum and ileum; they terminate in the superior mesenteric vein. Synonym: venae jejunales et ilei. (05 Mar 2000) |
| venae labiales anteriores | Tributaries of the femoral or external pudendal veins draining the mons pubis and anterior labia majora. Synonym: venae labiales anteriores. (05 Mar 2000) |
| venae labiales posteriores | They pass posteriorly from the labia majora and minora to the internal pudendal veins. Synonym: venae labiales posteriores. (05 Mar 2000) |
| venae labyrinthi | One or more veins accompanying the labyrinthine artery; they drain the internal ear, pass out through the internal acoustic meatus, and empty into the transverse sinus or the inferior petrosal sinus. Synonym: venae labyrinthi, internal auditory veins. (05 Mar 2000) |
| venae lumbales | Five in number, these veins accompany the lumbar arteries, drain the posterior body wall and the lumbar vertebral venous plexuses, and terminate anteriorly as follows: the first and second in the ascending lumbar vein, the third and fourth in the inferior vena cava, and the fifth in the iliolumbar vein; all communicate via the ascending lumbar veins. Synonym: venae lumbales. (05 Mar 2000) |
| venae mediastinales | Several small veins from the mediastinum emptying into the brachiocephalic veins or the superior vena cava. Synonym: venae mediastinales. (05 Mar 2000) |
| venae medullae oblongatae | Several veins draining the medulla oblongata; they are tributaries of the anterior spinal vein and the petrosal vein. Synonym: veins of medulla oblongata. (05 Mar 2000) |
