| dorsal metatarsal ligaments | Fibrous bands that connect the dorsal aspects of the bases of the metatarsals. Synonym: ligamenta metatarsalia dorsalia. (05 Mar 2000) |
|---|---|
| dorsal metatarsal veins | Veins arising from the dorsal digital veins forming the dorsal venous arch of the foot. Synonym: venae metatarseae dorsales. (05 Mar 2000) |
| dorsal motor nucleus of vagus | The visceral motor nucleus located in the vagal trigone (ala cinerea) of the floor of the fourth ventricle. It gives rise to the parasympathetic fibres of the vagus nerve innervating the heart muscle and the smooth musculature and glands of the respiratory and intestinal tracts. Synonym: nucleus dorsalis nervi vagi, dorsal motor nucleus of vagus, dorsal nucleus of vagus, dorsal vagal nucleus, nucleus alae cinereae. (05 Mar 2000) |
| dorsal muscles | The muscles of the back in general, including those attaching the shoulder girdle to the trunk posteriorly, the posterior serratus muscles, and the erector spinae. Synonym: musculi dorsi, dorsal muscles. (05 Mar 2000) |
| dorsal nasal artery | Origin, ophthalmic; external artery of the nose; distribution, skin of side of root of nose; anastomoses, angular artery. Synonym: arteria dorsalis nasi, arteria nasi externa, dorsal artery of nose, external artery of nose. (05 Mar 2000) |
| dorsal nerves of toes | Nerves supplying the skin of the dorsal aspect of the proximal and middle phalanges of the toes. Synonym: nervi digitales dorsales pedis, dorsal nerves of toes. (05 Mar 2000) |
| dorsal nucleus | A column of large neurons located in the base of the posterior gray column of the spinal cord, extending from the first thoracic through the second lumbar segment; it gives rise to the dorsal spinocerebellar tract of the same side. Synonym: nucleus thoracicus, Clarke's column, Clarke's nucleus, dorsal nucleus, nucleus dorsalis, Stilling's column, Stilling's nucleus. (05 Mar 2000) |
| dorsal nucleus of trapezoid body | A circumscript, bipartite cell group located ventrolaterally in the lower pontine tegmentum, immediately dorsal to the trapezoid body; the nucleus receives fibres from both the ipsilateral and contralateral cochlear nuclei, and contributes fibres to the lateral (auditory) lemniscus of both sides. It is believed to be prominently involved in the function of spatial localization of sound. Synonym: nucleus dorsalis corporis trapezoidei, oliva superior, superior olivary nucleus, superior olive. (05 Mar 2000) |
| dorsal nucleus of vagus | The visceral motor nucleus located in the vagal trigone (ala cinerea) of the floor of the fourth ventricle. It gives rise to the parasympathetic fibres of the vagus nerve innervating the heart muscle and the smooth musculature and glands of the respiratory and intestinal tracts. Synonym: nucleus dorsalis nervi vagi, dorsal motor nucleus of vagus, dorsal nucleus of vagus, dorsal vagal nucleus, nucleus alae cinereae. (05 Mar 2000) |
| dorsal pancreatic artery | <anatomy, artery> Origin, splenic; distribution, head and body of pancreas; anastomoses, superior pancreaticoduodenal. Synonym: arteria pancreatica dorsalis, great superior pancreatic artery. (05 Mar 2000) |
| dorsal part of pons | The part of the pons bounded laterally by the middle cerebellar peduncles and anteriorly by the ventral part of pons; it is continuous with the tegmentum of the mesencephalon and contains long tracts such as the medial and lateral lemnisci, cranial nerve nuclei, and reticular formation. Synonym: pars dorsalis pontis, tegmentum of pons. (05 Mar 2000) |
| dorsal plate of neural tube | The thin layer of the embryonic neural tube connecting the alar plate's dorsally. Synonym: dorsal plate of neural tube. (05 Mar 2000) |
| dorsal position | The posture of an individual lying face up. (12 Dec 1998) |
| dorsal radiocarpal ligament | <anatomy> The ligament that extends from the distal end of the radius posteriorly to the proximal row of carpal bones. Synonym: ligamentum radiocarpale dorsale. (05 Mar 2000) |
| dorsal reflex | Contraction of the muscles of the back elicited by cutaneous stimulation over the erector spinal muscle. (05 Mar 2000) |
