| dorsal interosseous artery | <anatomy, artery> Origin, common interosseous artery; distribution, posterior compartment of forearm. Synonym: arteria interossea posterior, dorsal interosseous artery. (05 Mar 2000) |
| dorsal interosseous muscles of foot | Four muscles in the foot; origin, from sides of adjacent metatarsal bones; insertion, first into medial, second into lateral side of proximal phalanx of second toe, third and fourth into lateral side of proximal phalanx of third and fourth toes; action, abduct toes 2-4 from an axis through the second toe; nerve supply, lateral plantar. Synonym: musculi interossei dorsalis pedis. (05 Mar 2000) |
| dorsal interosseous muscles of hand | Four muscles in the hand; origin, sides of adjacent metacarpal bones; insertion, proximal phalanges and extensor expansion, first on radial side of index, second on radial side of middle finger, third on ulnar side of middle finger, fourth on ulnar side of ring finger; action, abduct fingers 2-4 from the axis of the middle finger, nerve supply, ulnar. Synonym: musculi interossei dorsalis manus. (05 Mar 2000) |
| dorsal interosseous nerve | <anatomy, nerve> The deep terminal branch of the radial nerve, arises in the cubital region, penetrating and supplying the supinator and continuing with the posterior interosseous artery to supply all the extensor muscles in the forearm. Synonym: nervus interosseus posterior, nervus antebrachii posterior, deep branch of the radial nerve, dorsal interosseous nerve, nervus interosseus dorsalis, posterior antebrachial nerve. (05 Mar 2000) |
| dorsal lateral cutaneous nerve | <anatomy, nerve> The continuation of the sural nerve in the foot, supplying the lateral margin and dorsum. Synonym: nervus cutaneus dorsalis lateralis, dorsal lateral cutaneous nerve. (05 Mar 2000) |
| dorsal lingual branches of lingual artery | <anatomy, artery> Branches of the lingual artery to the posterior third or root of tongue. Synonym: rami dorsales linguae arteriae lingualis. (05 Mar 2000) |
| dorsal lingual vein | <anatomy, vein> Multiple tributaries of the lingual vein draining the dorsum of the tongue, becoming increasingly larger toward the root of the tongue. Synonym: venae dorsales linguae. (05 Mar 2000) |
| dorsal longitudinal fasciculus | A bundle of thin, poorly myelinated nerve fibres reciprocally connecting the periventricular zone of the hypothalamus with ventral parts of the central gray substance of the midbrain. Synonym: fasciculus longitudinalis dorsalis, Schutz' bundle, tract of Schutz. (05 Mar 2000) |
| dorsal medial cutaneous nerve | <anatomy, nerve> The medial terminal branch of the superficial peroneal nerve, supplying the dorsum of the foot and dorsal nerves to the toes (except adjacent sides of great and second toes). Synonym: nervus cutaneus dorsalis medialis, dorsal medial cutaneous nerve. (05 Mar 2000) |
| dorsal mesogastrium | <anatomy> The umbilical region. The mesogaster. Origin: NL. See Mesogaster. Source: Websters Dictionary (01 Mar 1998) |
| dorsal metacarpal artery | <anatomy, artery> One of four arteries taking origin from the dorsal carpal arch and running on the posterior aspect of the interosseous muscles of the hand. Synonym: arteria metacarpea dorsalis, dorsal interosseous artery. (05 Mar 2000) |
