| palmar metacarpal ligaments | Fibrous bands connecting the palmar aspects of the bases of metacarpals two to five. Synonym: ligamenta metacarpalia palmaria. (05 Mar 2000) |
|---|---|
| palmar metacarpal veins | Veins emptying into the deep venous arch from which the radial and ulnar veins arise. Synonym: venae metacarpeae palmares. (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) |
| metacarpal | One of the five bones to each digit in the hand. Metacarpals articulate with the carpal bones in the wrist and the phalanges (finger bone). (27 Sep 1997) |
| metacarpal bone | One of the metacarpal bones, five long bones (numbered I to V, beginning with the bone on the radial or thumb side) forming the skeleton of the metacarpus or palm; they articulate with the bones of the distal row of the carpus and with the five proximal phalanges. Synonym: os metacarpale. (05 Mar 2000) |
| metacarpal index | The average ratio of length to breadth of metacarpals II to V; this ratio is increased in the Marfan syndrome. (05 Mar 2000) |
| metacarpal veins | See: dorsal metacarpal veins, palmar metacarpal veins. (05 Mar 2000) |
| head of metacarpal bone | The expanded distal end of a metacarpal that articulates with the proximal phalanx of the same digit. Synonym: caput ossis metacarpalis. (05 Mar 2000) |
| styloid process of third metacarpal bone | A pointed projection from the dorsolateral angle of the base of the third metacarpal bone; it sometimes exists as a separate ossicle. Synonym: processus styloideus ossis metacarpalis III. (05 Mar 2000) |
| superficial transverse metacarpal ligament | <anatomy> A thickening of the deep fascia in the most distal part of the (base) of the triangular palmar aponeurosis. Synonym: ligamentum metacarpale transversum superficiale, Gerdy's fibres, ligamentum natatorium. (05 Mar 2000) |
| deep transverse metacarpal ligament | <anatomy> The ligament that interconnects the palmar surface of the heads of the second to fifth metacarpals, being continuous with the palmar ligaments on palmar plates; it lies in the plane of the palmar interosseous fascia. Synonym: ligamentum metacarpale transversum profundum, transverse metacarpal ligament. (05 Mar 2000) |
| 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) |
| dorsal metacarpal ligaments | Fibrous bands connecting the dorsal aspects of the bases of metacarpals two to five. Synonym: ligamenta metacarpalia dorsalia. (05 Mar 2000) |
| dorsal metacarpal veins | Three veins on the dorsum of the hand draining blood from the four medial digits into the dorsal venous network of the hand. Synonym: venae metacarpeae dorsales. (05 Mar 2000) |
| transverse metacarpal ligament | <anatomy> The ligament that interconnects the palmar surface of the heads of the second to fifth metacarpals, being continuous with the palmar ligaments on palmar plates; it lies in the plane of the palmar interosseous fascia. Synonym: ligamentum metacarpale transversum profundum, transverse metacarpal ligament. (05 Mar 2000) |
