| cephalic vein | <anatomy, vein> Arises at the radial border of the dorsal venous rete of the hand, passes upward in front of the elbow and along the lateral side of the arm; it empties into the upper part of the axillary vein. Synonym: vena cephalica. (05 Mar 2000) |
| retromandibular vein | <anatomy, vein> It is formed by the union of the superficial temporal and maxillary veins in front of the ear, runs posterior to the ramus of the mandible through the parotid gland, and unites with the posterior auricular vein to form the external jugular vein; it usually has a large communicating branch with the facial vein. Synonym: vena retromandibularis, posterior facial vein, temporomaxillary vein, vena facialis posterior. (05 Mar 2000) |
| great cardiac vein | <anatomy, vein> Begins at the apex of the heart (where it anastomoses with the middle cardiac vein), runs first with the anterior interventricular artery as it ascends the anterior interventricular groove, then turns to the left as it approaches or reaches the coronary groove to run with the circumflex branch of the left coronary artery; it merges with the oblique vein of the left atrium to form the coronary sinus. Synonym: vena cordis magna, left coronary vein, vena cardiaca magna. (05 Mar 2000) |
| great cerebral vein | A large, unpaired vein formed by the junction of the two internal cerebral veins in the caudal part of the tela choroidea of the third ventricle; it passes caudally between the splenium of the corpus callosum and the pineal gland, curving dorsally to merge with the inferior sagittal sinus to form the straight sinus. Synonym: vena cerebri magna, great cerebral vein, great vein of Galen. (05 Mar 2000) |
| great cerebral vein of Galen | A large, unpaired vein formed by the junction of the two internal cerebral veins in the caudal part of the tela choroidea of the third ventricle; it passes caudally between the splenium of the corpus callosum and the pineal gland, curving dorsally to merge with the inferior sagittal sinus to form the straight sinus. Synonym: vena cerebri magna, great cerebral vein, great vein of Galen. (05 Mar 2000) |
| great saphenous vein | <anatomy, vein> Formed by the union of the dorsal vein of the great toe and the dorsal venous arch of the foot, ascends in front of the medial malleolus, behind the medial condyle of the femur, and traverses the saphenois hiatus in the fascia lata to empty into the femoral vein in the upper part of the femoral triangle. Synonym: vena saphena magna, large saphenous vein, long saphenous vein. (05 Mar 2000) |
| great vein of Galen | A large, unpaired vein formed by the junction of the two internal cerebral veins in the caudal part of the tela choroidea of the third ventricle; it passes caudally between the splenium of the corpus callosum and the pineal gland, curving dorsally to merge with the inferior sagittal sinus to form the straight sinus. Synonym: vena cerebri magna, great cerebral vein, great vein of Galen. (05 Mar 2000) |
| right branch of portal vein | <anatomy, vein> Terminal branch of hepatic portal vein distributed to right lobe of liver tributary: cystic vein. Synonym: ramus dexter venae portae hepatis. (05 Mar 2000) |
| right colic vein | <anatomy, vein> The vein that parallels the right colic artery and drains blood from the ascending colon and right colic flexure. Synonym: vena colica dextra. (05 Mar 2000) |
| right gastric vein | <anatomy, vein> It receives veins from both surfaces of the upper portion of the stomach, runs to the right along the lesser curvature of the stomach, and empties into the portal vein. Synonym: vena gastrica dextra, pyloric vein. (05 Mar 2000) |
| right gastroepiploic vein | <anatomy, vein> A tributary of the superior mesenteric vein that parallels the right gastroepiploic artery along the greater curvature of the stomach. Synonym: vena gastro-omentalis dextra, right gastroomental vein. (05 Mar 2000) |
| right gastroomental vein | <anatomy, vein> A tributary of the superior mesenteric vein that parallels the right gastroepiploic artery along the greater curvature of the stomach. Synonym: vena gastro-omentalis dextra, right gastroomental vein. (05 Mar 2000) |
