| venae rectae | The ascending limbs of the vasa rectae in the renal medulla. (05 Mar 2000) |
|---|---|
| venae rectales inferiores | Veins that pass to the internal pudendal vein from the inferior rectal venous plexus around the anal canal. Synonym: venae rectales inferiores. (05 Mar 2000) |
| venae rectales mediae | Several veins that pass from the rectal venous plexus (in which they anastomose with the superior rectal veins) to the internal iliac vein, which ultimately drains into the inferior vena cava. Since the superior rectal veins ultimately drain into the portal vein, the middle retal veins participate in a portocaval anastomosis, and the rectal venous plexus is subject to varicosities during portal hypertension. Synonym: venae rectales mediae. (05 Mar 2000) |
| venae renales | Large veins formed at the renal hilus by the merger of the segmental veins anterior to the corresponding arteries; they open at right angles into the inferior vena cava at the level of the second lumbar vertebra. The left renal vein receives the left suprarenal vein and the left gonadal vein, and passes through the angle between the abdominal aorta and superior mesenteric artery where it may be compressed. Synonym: venae renales. (05 Mar 2000) |
| venae renis | The tributaries of the renal vein that drain the kidney; they parallel the arteries in the kidney and consist of interlobular, arcuate, and interlobar veins. Synonym: venae renis. (05 Mar 2000) |
| venae sacrales laterales | Several veins that receive the drainage of the sacral venous plexus and sacral intervertebral veins then accompany the corresponding artery and empty into the internal iliac vein on each side. Synonym: venae sacrales laterales. (05 Mar 2000) |
| venae sclerales | Small veins draining the sclera; they are tributaries to the anterior ciliary veins. Synonym: venae sclerales. (05 Mar 2000) |
| venae scrotales anteriores | Tributaries of the femoral or exteranl pudendal veins drainign the anterior aspect of the scrotum and the skin and dartos fascia of the shaft and base of the penis. Synonym: venae scrotales anteriores. (05 Mar 2000) |
| venae scrotales posteriores | Veins from the posteriro aspect of the scrotum to the internal pudendal veins. Synonym: venae scrotales posteriores. (05 Mar 2000) |
| venae sigmoideae | The several tributaries of the inferior mesenteric vein that drain the sigmoid colon. Synonym: venae sigmoideae. (05 Mar 2000) |
| venae spinales | The veins that drain the spinal cord; they form a plexus on the surface of the cord from which veins pass along the spinal roots to the internal vertebral venous plexus. Synonym: venae spinales. (05 Mar 2000) |
| venae stellatae | The star-shaped groups of venules in the renal cortex. Synonym: stellate veins, stellate venules, stellulae verheyenii, venae stellatae, Verheyen's stars. (05 Mar 2000) |
| venae striatae | Veins draining the thalamus and striate body exiting the anterior perforated substance; tributary to the basal vein. Synonym: venae thalamostriatae inferiores, striate veins, venae striatae. (05 Mar 2000) |
| venae subcutaneae abdominis | The network of superficial veins of the abdominal wall that empty into the thoracoepigastric, superficial epigastric, or superior epigastric veins and form portocaval anastomoses through their communications with the paraumbilical veins. Synonym: venae subcutaneae abdominis. (05 Mar 2000) |
| venae supratrochleares | Several veins that drain the front part of the scalp and unite with the supraorbital vein to form the angular vein. Synonym: venae supratrochleares, frontal veins, venae frontales, venae frontales. (05 Mar 2000) |
