| 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.

| 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) |
| 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 mandibular branch of facial nerve | <anatomy, nerve> Branch of facial nerve which parallels the mandibular margin innervating risorius muscle and muscles of lower lip and chin. Synonym: ramus marginalis mandibulae nervi facialis. (05 Mar 2000) |
| genital branch of genitofemoral nerve | <anatomy, nerve> Branch of genitofemoral nerve distributed to skin of anterior scrotum (male) or labia majora (female) and adjacent thigh and supplying a motor branch to the cremaster muscle. Usually passes through deep inguinal ring and canal. Synonym: ramus genitalis nervi genitofemoralis, external spermatic nerve, nervus spermaticus externus. (05 Mar 2000) |
| genital branch of iliohypogastric nerve | <anatomy, nerve> Distribution, skin on pubis. Synonym: ramus cutaneus anterior nervi iliohypogastrici, genital branch of iliohypogastric nerve. (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) |
| recurrent meningeal branch of spinal nerves | A branch from the initial (mixed) part of each spinal nerve passing in a recurrent fashion back through the intervertebral foramen to supply spinal meninges, the posterior longitudinal ligament, posterolateral periphery of the intervertebral disc, and periosteum of the vertebrae. Synonym: ramus meningeus nervorum spinalium, recurrent meningeal branch of spinal nerves, sinuvertebral nerves. (05 Mar 2000) |
| medial cutaneous branch | Nomina Anatomica lists medial cutaneous branch of the following: 1) dorsal branch of thoracic nerves, ramus cutaneus medialis ramorum dorsalium nervorum thoracicorum; 2) dorsal branch of posterior intercostal arteries, ramus cutaneus medialis rami dorsalis arteriarum intercostalium posteriorum III-XI. Synonym: ramus cutaneus medialis. (05 Mar 2000) |
| renal branch of lesser splanchnic nerve | <anatomy, nerve> Branch of lesser splanchnic nerve to the aorticorenal plexus/ganglion. Synonym: ramus renalis nervi splanchnici minoris. (05 Mar 2000) |
| renal branch of vagus nerve | <anatomy, nerve> Branches of vagus nerve to kidney via the coeliac plexus. Synonym: rami renales nervi vagi. (05 Mar 2000) |
| pectoral and abdominal anterior cutaneous branch of intercostal nerves | The ventral primary rami of spinal nerves T7-T11 (seventh to eleventh intercostal nerves), which supply the abdominal as well as the thoracic wall; innervate intercostal, subcostal, serratus posterior inferior, transversus abdominis, external and internal oblique, and rectus abdominis muscles, and provide sensory branches to the periphery of the diaphragm, and parietal pleura and peritoneum. Synonym: rami cutanei anteriores pectoralis et abdominalis nervorum intercostalium, ramus cutaneus anterior (pectoralis et abdominalis) nervorum thoracicorum, anterior cutaneous nerves of abdomen, pectoral and abdominal anterior cutaneous branch of intercostal nerves. (05 Mar 2000) |
| cervical branch of facial nerve | <anatomy, nerve> The most inferior branch of the parotid plexus of the facial nerve, it descends to innervate the platysma muscle. Synonym: ramus colli nervi facialis, ramus cervicalis nervi facialis. (05 Mar 2000) |
