| venae metatarseae plantares | Veins receiving the plantar digital veins and draining in turn into the deep plantar venous arch, which empties into the medial and lateral plantar veins. Synonym: venae metatarseae plantares. (05 Mar 2000) |
| venae musculophrenicae | The veins that accompany the musculophrenic artery and drain blood from the upper abdominal wall, and anterior portions of the lower intercostal spaces and the diaphragm. Synonym: venae musculophrenicae. (05 Mar 2000) |

| venae oesophageae | 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.
