| metatarsal | One of five bones that travel out to each toe in the foot. The metatarsals articulate with the tarsal bones in the hindfoot and the phalanges (toes) in the forefoot. (27 Sep 1997) |
|---|---|
| metatarsal artery | <anatomy, artery> One of four dorsal or four plantar arteries coursing in relation to the metatarsal bones, each dividing distally into a medial and a lateral digital artery, serving the dorsal or plantar aspects of adjacent sides of two toes. See: dorsal metatarsal artery, plantar metatarsal artery. Synonym: arteria metatarsae. (05 Mar 2000) |
| metatarsal bone | One of the metatarsal bones; the five long bones numbered I to V beginning with the bone on the medial side forming the skeleton of the anterior portion of the foot, articulating posteriorly with the three cuneiform and the cuboid bones, anteriorly with the five proximal phalanges. Synonym: os metatarsale. (05 Mar 2000) |
| metatarsal bones | The five long bones of the metatarsus articulating with the tarsal bones proximally and the toes (phalanges) distally. (12 Dec 1998) |
| metatarsal reflex | Flexion of the toes on tapping over the cuboid bone; almost identical with Guillain-Barre reflex, and fundamentally similar to Rossolimo's reflex. Synonym: metatarsal reflex. (05 Mar 2000) |
| plantar metatarsal artery | <anatomy, artery> One of four branches of the plantar arterial arch that divide into plantar digital arteries to supply the toes. Synonym: arteria metatarsea plantaris. (05 Mar 2000) |
| plantar metatarsal ligaments | Fibrous bands connecting the plantar aspects of the bases of the metatarsals. Synonym: ligamenta metatarsalia plantaria. (05 Mar 2000) |
| plantar metatarsal veins | Veins receiving the plantar digital veins and draining in turn into the deep plantar venous arch, which empties into the medial and lateral plantar veins. Synonym: venae metatarseae plantares. (05 Mar 2000) |
| head of metatarsal bone | The expanded distal end of a metatarsal bone that articulates with the proximal phalanx of the same digit. Synonym: caput ossis metatarsalis. (05 Mar 2000) |
| superficial transverse metatarsal ligament | <anatomy> A thickening of the distal part (base) of the plantar aponeurosis, at the level of the heads of the metatarsal bones. Synonym: ligamentum metatarsale transversum superficiale. (05 Mar 2000) |
| deep transverse metatarsal ligament | <anatomy> The ligament that interconnects the plantar surface of the heads of the metatarsals, being continuous with the plantar ligaments. Synonym: ligamentum metatarsale transversum profundum, transverse metatarsal ligament. (05 Mar 2000) |
| dorsal metatarsal artery | <anatomy, artery> One of four arteries arising from the dorsalis pedis (I) and arcuate (II-IV) arteries and running on the dorsum of the interosseous muscles of the foot. Synonym: arteria metatarsea dorsalis. (05 Mar 2000) |
| 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) |
| transverse metatarsal ligament | <anatomy> The ligament that interconnects the plantar surface of the heads of the metatarsals, being continuous with the plantar ligaments. Synonym: ligamentum metatarsale transversum profundum, transverse metatarsal ligament. (05 Mar 2000) |
