| auricular branch of vagus nerve | <anatomy, nerve> A branch of the superior ganglion of the vagus, supplying the back of the pinna and the external acoustic meatus. Synonym: ramus auricularis nervi vagi, Arnold's nerve. (05 Mar 2000) |
|---|---|
| basal tentorial branch of internal carotid artery | <anatomy, artery> A small branch from the cavernous part of the internal carotid artery to the base of the tentorium. Synonym: ramus basalis tentorii arteriae carotidis internae. (05 Mar 2000) |
| branch | <plant biology> A natural division of a plant stem. (17 Dec 1997) |
| branch migration | <molecular biology> Movement of the branch point in a branched DNA sequence formed from two parent DNA molecules with practically identical sequences. (17 Dec 1997) |
| branch of auriculotemporal nerve to tympanic membrane | Sensory branch of the auriculotemporal nerve supplying the external surface of the tympanic membrane. Synonym: ramus membranae tympani nervi auriculotemporalis, nerve of tympanic membrane. (05 Mar 2000) |
| branch of glossopharyngeal nerve to stylopharyngeus muscle | <anatomy> Sole motor branch of the glossopharyngeal nerve to the stylopharyngeus muscle. Synonym: ramus musculi stylopharyngei nervi glossopharyngei. (05 Mar 2000) |
| branch to atrioventricular node | The atrioventricular branches or the nodal branches, the small arteries supplying the atrioventricular node; they usually arise from the right coronary artery where it starts to descend the posterior interventricular sulcus. Synonym: ramus nodi atrioventricularis, atrioventricular nodal branch, branch to atrioventricular node. (05 Mar 2000) |
| branch to sinuatrial node | Ascending atrial branch, usually (55%) arising from the anterior stem of the right coronary artery (but 35-45% arising from the circumflex branch of the left coronary artery), which runs around the base of the superior vena cava to reach the sinuatrial node. Synonym: ramus nodi sinuatrialis arteriae coronaria dextra, branch to sinuatrial node, sinuatrial nodal branch of right coronary artery, sinuatrial node artery. (05 Mar 2000) |
| branch to trigeminal ganglion | Ganglionic branch of internal carotid artery. (05 Mar 2000) |
| bundle-branch block | <cardiology, physiology> Abnormal conduction through one of the conductive branches which normally supply the right and left ventricles. Usually results in delayed conduction though either the right or left bundle branches where one ventricle is excited before the other because of absence of conduction in one of the branches of the bundle of His. Intraventricular block due to interruption of conduction in one of the two main branches of the bundle of His and manifested in the electrocardiogram by marked prolongation of the QRS complex; block of each branch has distinctive QRS morphology. (05 Mar 2000) |
| calcarine branch of medial occipital artery | <anatomy, artery> Branch of medial occipital artery which runs in relationship to the calcarine sulcus. Synonym: ramus calcarinus arteriae occipitalis medialis, arteria calcarina, calcarine artery. (05 Mar 2000) |
| ganglionic branch of internal carotid artery | <anatomy, artery> Branch to trigeminal ganglion; a small branch of the cavernous part of the internal carotid artery to the trigeminal ganglion. Synonym: ramus ganglii trigeminalis. (05 Mar 2000) |
| palmar branch of median nerve | <anatomy, nerve> Branch of median nerve arising proximal to flexor retinaculum and running superficial to it to supply skin of proximal central palm and thenar eminence. Since it does not traverse carpal tunnel, it is not affected by carpal tunnel syndrome, even though it supplies skin distal to carpal tunnel. Synonym: ramus palmaris nervi mediani. (05 Mar 2000) |
| palmar branch of ulnar nerve | <anatomy, nerve> Branch of ulnar nerve arising in distal forearm and accompanying palmar artery into hand where it supplies skin of little finger and medial half of ring finger and adjacent parts of palm. Synonym: ramus palmaris nervi ulnaris. (05 Mar 2000) |
| palmar carpal branch of radial artery | <anatomy, artery> A small branch of the radial artery that passes medially across the wrist to supply the carpal joints; it anastomoses with the anterior carpal branch of the ulnar artery. Synonym: ramus carpalis palmaris arteriae radialis, ramus carpeus palmaris arteriae radialis. (05 Mar 2000) |
