| vena vertebralis | <anatomy, vein> A vein derived from tributaries (venae comitantes) which run through the foramina in the transverse processes of the first six cervical vertebrae and form a plexus around the vertebral artery; it empties as a single trunk into the brachiocephalic veins. Synonym: vena vertebralis. (05 Mar 2000) |
| vena vertebralis accessoria | <anatomy, vein> A vein that accompanies the vertebral vein but passes through the foramen of the transverse process of the seventh cervical vertebra and opens independently into the brachiocephalic vein. Synonym: vena vertebralis accessoria. (05 Mar 2000) |
| vena vertebralis anterior | <anatomy, vein> The small vein that accompanies the ascending cervical artery; it opens below into the vertebral vein. Synonym: vena vertebralis anterior. (05 Mar 2000) |
| vena vitellina | <anatomy, vein> A vein returning blood from the yolk sac to the embryo. Synonym: vena vitellina. (05 Mar 2000) |
| groove for superior vena cava | A groove on the surface of the right lung, above the hilum, in which runs the superior vena cava. Synonym: sulcus venae cavae cranialis. (05 Mar 2000) |
| sinus of the vena cava | The portion of the cavity of the right atrium of the heart that receives the blood from the venae cavae; it is separated from the rest of the atrium by the crista terminalis. Synonym: sinus venarum cavarum. (05 Mar 2000) |
| sulcus for vena cava | A groove on the posterior surface of the liver between the caudate lobe and the right lobe which gives passage to the inferior vena cava. Synonym: sulcus venae cavae, fossa venae cavae, sulcus for vena cava. (05 Mar 2000) |
| superior vena cava | <anatomy> The major venous channel draining the thorax and head which ends in the right atrium. (19 Jan 1998) |
| superior vena cava obstruction | <cardiology, oncology> Blockage or narrowing of the superior vena cava, the major vein draining the upper body. May result from lymphoma, liver tumours, tuberculosis, histoplasmosis and aortic aneurysm. (19 Jan 1998) |
| superior vena cava syndrome | <syndrome> A narrowing or obstruction of the superior vena cava. Symptoms include facial swelling, arm swelling, neck swelling, headache, dizziness, fainting and reddening of the face and palms. This may occur secondary to cancer or other inflammatory conditions (tuberculosis, histoplasmosis). See: superior vena cava obstruction (19 Jan 1998) |
| inferior vena cava | The large venous trunk which receives blood from the lower extremities and from the pelvic and abdominal organs. It travels through the abdomen (from the lower extremities) and returns blood to the right atrium of the heart. (20 Sep 2002) |
