| ramus descendens | Branch of an artery or nerve passing inferiorly. Descending branches have been described for the following: descending branch of hypoglossal nerve, superior root of ansa cervicalis; descending branch of lateral circumflex femoral artery; descending branch of the occipital artery. Synonym: ramus descendens. (05 Mar 2000) |
| ramus descendens arteriae circumflexae femoris lateralis | <anatomy, artery> A major branch of the lateral circumflex femoral artery accompanying the nerve to the vastus lateralis muscle along the anterior border of that muscle and deep to the rectus femoris muscle, supplying both muscles. Anastomosis: with lateral superior genicular artery, i.e., it contributes to the articular network of the knee. Synonym: ramus descendens arteriae circumflexae femoris lateralis. (05 Mar 2000) |
| ramus descendens arteriae occipitalis | <anatomy, artery> Origin: occipital artery within occipital groove; distribution: posterior neck muscles and cervical trapezius muscle; anastomoses: superficial and deep cervical arteries, vertebral artery. Synonym: ramus descendens arteriae occipitalis, princeps cervicis artery, princeps cervicis. (05 Mar 2000) |
| ramus dexter | Of a pair of branches, the branch passing to the right side of the body, to the right member of a bilateral pair of structures, or to the right portion of an unpaired structure; the other member of the pair being a left branch. Synonym: ramus dexter. (05 Mar 2000) |
| ramus dexter arteriae hepaticae propriae | <anatomy, artery> Right branch of proper hepatic artery; terminal branch of proper hepatic artery supplying right lobe of liver; branch: cystic artery. Synonym: ramus dexter arteriae hepaticae propriae, right branch of proper hepatic artery. (05 Mar 2000) |
| ramus dexter venae portae hepatis | <anatomy, vein> Terminal branch of hepatic portal vein distributed to right lobe of liver tributary: cystic vein. Synonym: ramus dexter venae portae hepatis. (05 Mar 2000) |
| ramus digastricus nervi facialis | <anatomy, nerve> Branch of the facial nerve innervating the posterior belly of the digastric muscle. Synonym: ramus digastricus nervi facialis. (05 Mar 2000) |
| ramus dorsalis | <anatomy, nerve> The smaller, posteriorly-directed major terminal branch (with the ventral primary ramus) of all 31 pairs of mixed spinal nerves, formed at the intervertebral foramen and turning abruptly posteriorly to divide into lateral and medial branches, both of which will supply the deep (true) muscles of the back. The medial branch (rami medialis ) of the dorsal primary ramus also supplies articular branches to the zygopophyseal joints and the periosteum of the vertebral arch. In the neck and upper back, the medial branch continues through the deep and superficial back muscles to supply overlying skin; in the lower back, the lateral branch does this. Nomina Anatomica lists dorsal primary rami as "rami dorsales" for each group of spinal nerves: 1) cervical (nervorum cervicalium ), 2) thoracic (nervorum thoracicorum ), 3) lumbar (nervorum lumbalium ), 4) sacral (nervorum sacralium ), and 5) coccygeal (nervi coccygei ). Synonym: ramus dorsalis nervorum spinalium, ramus dorsalis, rami posteriores nervorum spinalium, dorsal branch, posterior primary division. (05 Mar 2000) |
| ramus dorsalis arteriae lumbalium | <anatomy, artery> Terminal branch (with ventral branch) of the 4-5 lumbar arteries, distributed to lumbar portion of back, posterior vertebral column, and spinal cord and environs. Synonym: ramus dorsalis arteriae lumbalium. (05 Mar 2000) |
| ramus externus nervi accessorii | <anatomy, nerve> Originates from the upper five or six cervical spinal segments, emerges from the lateral surface of the spinal cord and ascends through the foramen magnum to join the cranial root. Synonym: radices spinales nervi accessorii, ramus externus nervi accessorii, pars spinalis nervi accessorii, spinal part of accessory nerve. (05 Mar 2000) |
| ramus externus nervi laryngei superioris | <anatomy, nerve> Terminal branch of superior laryngeal nerve (with internal laryngeal nerve) supplying motor innervation to cricothyroid muscle. Synonym: ramus externus nervi laryngei superioris. (05 Mar 2000) |
