| perforating branches | Arterial branches which penetrate a wall or pass from the anterior to the posterior aspect or compartment of a structure such as the hand or foot to anastomose or be distributed. Synonym: ramus perforans, perforating peroneal artery. (05 Mar 2000) |
|---|---|
| perforating branches of internal thoracic artery | <anatomy, artery> Small branches of the internal thoracic artery running between the costal cartilages to supply overlying skin and subcutaneous tissues. Synonym: ramus perforantes arteriae thoracicae internae, perforating arteries of internal mammary. (05 Mar 2000) |
| perforating branches of palmar metacarpal arteries | The perforating branches of the palmar metacarpal arteries, three small arteries that pass dorsally through the second, third, and fourth interosseous spaces of the hand from the palmar metacarpal arteries. Synonym: ramus perforantes arteriarum metacarpalium palmarium, perforating arteries of hand. (05 Mar 2000) |
| perforating branches of plantar metatarsal arteries | The perforating branches of the plantar metatarsal arteries, three small arteries that pass dorsally through the second, third, and fourth interosseous spaces of the foot from the plantar metatarsal arteries. Synonym: ramus perforantes arteriarum metatarsearum plantarium, perforating arteries of foot. (05 Mar 2000) |
| mental branches of mental nerve | <anatomy, nerve> Branches of the mental nerve providing general sensory innervation to the skin of the chin. Synonym: rami mentales nervi mentalis. (05 Mar 2000) |
| right coronary artery branches | <radiology> Conus branch, branch to S-A node, acute marginal branches, branches to posterior left ventricle, branch to A-V node, posterior descending artery (patent ductus arteriosus, 90%), hence, right coronary a. Is usually dominant (12 Dec 1998) |
| choroid branches | The choroid branches: ramus choroidei posteriores laterales, lateral posterior choroid branches of posterior cerebral artery distributed to the choroid plexus of the lateral ventricle; ramus choroidei posteriores mediales, medial posterior choroid branches of posterior cerebral artery distributed to the choroid plexus of the third ventricle; ramus choroidei ventriculi lateralis, lateral ventricle choroid branch of anterior choroid artery distributed to the plexus of the lateral ventricle; ramus choroidei ventriculi tertii, third ventricle choroid branch of anterior choroid artery to the third ventricle; ramus choroidei ventriculi quarti, fourth ventricle choroid branch of posterior inferior cerebellar artery. Synonym: rami choroidei. (05 Mar 2000) |
| pharyngeal branches | Branches to the pharynx. Synonym: pharyngei, rami pharyngeales. (05 Mar 2000) |
| coeliac branches of vagus nerve | <anatomy, nerve> Terminal branches of the posterior vagal trunk conveying presynaptic parasympathetic fibres to-and visceral afferent fibres from-the coeliac plexus. Synonym: rami coeliaci nervi vagi. (05 Mar 2000) |
| communicating branches of auriculotemporal nerve to facial nerve | <anatomy, nerve> Branches conveying fibres from the auriculotemporal nerve to the facial nerve. Synonym: rami communicantes nervi auriculotemporalis cum nervo faciali. (05 Mar 2000) |
| communicating branches of lingual nerve to hypoglossal nerve | <anatomy, nerve> Communicating branches between the lingual nerve (from mandibular nerve) and hypoglossal nerve forming a plexus on the hypoglossus muscle. Synonym: rami communicantes nervi lingualis cum nervo hypoglosso. (05 Mar 2000) |
| communicating branches of spinal nerves | Short nerves arising from the initial portion of the ventral primary rami of the thoracic and upper lumbar spinal nerves through which all presynaptic sympathetic nerve fibres must pass to reach the sympathetic trunks; also conveyed by the white rami communicans are visceral afferent (sensory) fibres which were conveyed to the sympathetic trunks in splanchnic nerves. Most fibres conveyed by the white rami communicantes are myelinated. Synonym: rami communicantes nervorum spinalium, communicating branches of spinal nerves. (05 Mar 2000) |
| communicating branches of sympathetic trunk | Short nerves arising from the lateral aspect of the sympathetic trunk conducting nonmyelinated postsynaptic sympathetic nerve fibres from the sympathetic trunk to the initial portions of all 31 pairs of ventral primary rami of spinal nerves for distribution by all parts (including the dorsal primary ramus) of the spinal nerve. The gray rami are the parietal branches of the sympathetic trunks since all postsynaptic fibres to be distributed to the body wall (including limbs) must pass through them. Synonym: communicating branches of sympathetic trunk, communicating rami of sympathetic trunk. (05 Mar 2000) |
| muscular branches | Usually unnamed branches of nerves or vessels that supply the muscles. Synonym: rami musculares. (05 Mar 2000) |
| coronary artery branches | <radiology> Right coronary artery, left coronary artery (12 Dec 1998) |
