| vena comitans | A vein accompanying another structure. Synonym: accompanying vein, companion vein. (05 Mar 2000) |
|---|---|
| vena comitans nervi hypoglossi | Runs with the hypoglossal nerve below and lateral to the hyoglossus muscle, emptying usually into the lingual vein. Synonym: accompanying vein of hypoglossal nerve. (05 Mar 2000) |
| vena cordis magna | <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) |
| vena cordis media | <anatomy, vein> Begins at the apex of the heart (where it anastomoses with the great cardiac vein), and ascends within the posterior interventricular sulcus to the coronary sinus. Synonym: vena cordis media, inferior cardiac vein. (05 Mar 2000) |
| vena cordis parva | <anatomy, vein> An inconstant vessel, accompanying the right coronary artery in the coronary sulcus, from the right margin of the right ventricle, and emptying into the coronary sinus or the middle cardiac vein. Synonym: vena cordis parva. (05 Mar 2000) |
| vena cornus posterioris | A small vein draining the surface region of the posterior horn of the lateral ventricle; it is a tributary to the great cerebral vein. Synonym: vein of posterior horn. (05 Mar 2000) |
| vena coronaria ventriculi | <anatomy, vein> Arises from a union of veins from both surfaces of the cardia of the stomach and an oesophageal tributary from the cardiac portion of the oesophagus; it runs in the lesser omentum and empties into the portal vein. See: oesophageal veins. Synonym: vena gastrica sinistra, coronary vein, vena coronaria ventriculi. (05 Mar 2000) |
| vena corporis callosi dorsalis | It originates on the superior surface of the corpus callosum and runs posteriorly to terminate in the great cerebral vein. Synonym: dorsal callosal vein, dorsal vein of corpus callosum, posterior marginal vein, posterior pericallosal vein. (05 Mar 2000) |
| vena cutanea | <anatomy, vein> One of a number of veins that course in the subcutaneous tissue and empty into deep veins; they form prominent systems of vessels in the limbs and are usually not accompanied by arteries. Synonym: vena cutanea, cutaneous vein. (05 Mar 2000) |
| vena cystica | <anatomy, vein> Veins, usually anterior and posterior, which drain the neck of the gallbladder and cystic duct, along which they pass to enter the right branch of the portal vein; they communicate extensively with surrounding veins of the stomach, duodenum and pancreas. Synonym: vena cystica. (05 Mar 2000) |
| vena diploica | <anatomy, vein> One of the veins in the diploe of the cranial bones, connected with the cerebral sinuses by emissary veins; the main diploic veins are the frontal, anterior temporal, posterior temporal, and occipital. Synonym: vena diploica, Breschet's vein, Dupuytren's canal. (05 Mar 2000) |
| vena dorsalis clitoridis profunda | A tributary of the vesical venous plexus; it runs a course deep to the fascia on the dorsum of the clitoris. Synonym: vena dorsalis clitoridis profunda. (05 Mar 2000) |
| vena dorsalis penis profunda | A vein on the dorsum of the penis deep to the fascia of the penis; it is a tributary to the prostatic venous plexus. Synonym: vena dorsalis penis profunda. (05 Mar 2000) |
| vena emissaria | <anatomy, vein> One of the channels of communication between the venous sinuses of the dura mater and the veins of the diploe and the scalp. See: condylar emissary vein, mastoid emissary vein, occipital emissary vein, parietal emissary vein. Synonym: vena emissaria, emissarium, emissary. (05 Mar 2000) |
| vena emissaria condylaris | <anatomy, vein> A vein that connects the sigmoid sinus and the external vertebral venous plexuses through the condylar canal of the occipital bone. Synonym: vena emissaria condylaris, emissarium condyloideum. (05 Mar 2000) |
