| interlobular veins of liver | 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) |
|---|---|
| internal auditory veins | 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) |
| internal cerebral veins | Paired veins passing caudally near the midline in the tela choroidea of the third ventricle, formed by the union of the choroid vein, thalamostriate (terminal) vein, and vein of septum pellucidum, and uniting caudally so as to form the great cerebral vein. Synonym: venae cerebri internae, veins of Galen. (05 Mar 2000) |
| intersegmental veins | A vein receiving blood from adjacent bronchopulmonary segments; it emerges from the inferior margin of a segment to become a tributary of a branch of a pulmonary vein. Synonym: infrasegmental part, intersegmental part of pulmonary vein, pars infrasegmentalis. (05 Mar 2000) |
| intrasegmental veins | A vein emerging from the bronchopulmonary segment it drains; a tributary to a branch of a pulmonary vein. Synonym: pars intrasegmentalis, intrasegmental part. (05 Mar 2000) |
| occipital cerebral veins | The superior cerebral veins draining the occipital cortex and emptying into the superior sagittal sinus and the transverse sinus. Synonym: venae occipitales. (05 Mar 2000) |
| oesophageal veins | Series of veins draining the submucous venous plexus of the oesophagus; proceding inferiorly from the cervical portion of the oesophagus, they drain to the inferior thyroid vein, the superior intercostal veins, the azygos, accessory hemiazygos and hemiazygos veins, all of which are ultimately tributaries of the superior vena cava; the most inferior oesophageal veins, from the cardiac portion of the oesophagus, drain via the oesophageal branches of the left gastric vein, a tributary of the portal vein. Thus, the submucosal veins of the inferior oesophagus form a portocaval anastomoses, and are subject to the formation of varicosities in portal hypertension. Synonym: venae oesophageae. (05 Mar 2000) |
| openings of pulmonary veins | The orifices of the pulmonary veins, usually two on each side, in the wall of the left atrium. Synonym: ostia venarum pulmonalium. (05 Mar 2000) |
| ophthalmic veins | See: inferior ophthalmic vein, superior ophthalmic vein. (05 Mar 2000) |

| temporal veins | See: middle temporal vein, deep temporal veins, superficial temporal veins. (05 Mar 2000) |
| testicular veins | See: right testicular vein, left testicular vein. (05 Mar 2000) |
| thalamostriate veins | See: inferior thalamostriate veins, superior thalamostriate vein. (05 Mar 2000) |
| thebesian veins | Synonym: venae cordis minimae. (05 Mar 2000) |
