| 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.

| 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 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) |
| palmar carpal branch of ulnar artery | <anatomy, artery> A branch of the ulnar artery that supplies the carpal joints and communicates with the anterior carpal branch of the radial artery. Synonym: ramus carpalis palmaris arteriae ulnaris, ramus carpeus palmaris arteriae ulnaris. (05 Mar 2000) |
| ventral branch | Rami ventralis See: ventral primary rami of cervical spinal nerves, ventral primary rami of lumbar spinal nerves, ventral primary rami of sacral spinal nerves, ventral primary ramus of spinal nerve. (05 Mar 2000) |
| marginal tentorial branch of internal carotid artery | <anatomy, artery> A small branch from the cavernous part of the internal carotid artery to the free margin of the tentorium. Synonym: ramus marginalis tentorii arteriae carotidis internae. (05 Mar 2000) |
| carotid sinus branch | <anatomy, nerve> A branch of the glossopharyngeal nerve that innervates the baroreceptors in the wall of the carotid sinus and the chemoreceptors in the carotid body. Synonym: ramus sinus carotici, carotid sinus branch, Hering's sinus nerve, intercarotid nerve, nerve to carotid sinus, sinus nerve of Hering. (05 Mar 2000) |
| parietal branch | Branches coursing in relationship to and supplying the parietal bone or parietal lobe of cerebrum, branches distributed to the body wall and limbs (the "parities") as opposed to visceral branches distributed to the body cavities. For example, the gray rami communicantes are the parietal branches of the sympathetic trunks (vs. The splanchnic nerves, which are visceral branches of the trunks). Synonym: rami parietales. (05 Mar 2000) |
| parietal branch of medial occipital artery | <anatomy, artery> An anterior branch of the medial occipital artery supplying the posterior section of the parietal lobe of the cerebrum. Synonym: ramus parietalis arteriae occipitalis medialis. (05 Mar 2000) |
| parietal branch of middle meningeal artery | <anatomy, artery> Smaller terminal branch (with frontal branch) of middle meningeal artery supplying posterior portion of lateral and superior dura and cranium. Synonym: ramus parietalis arteriae meningeae mediae. (05 Mar 2000) |
| parietal branch of superficial temporal artery | <anatomy, artery> Branches coursing in relationship to and/or supplying the parietal lobe of the brain. Synonym: ramus parietalis arteriae temporalis superficialis. (05 Mar 2000) |
