| interosseous margin | Edge of a bone to which a fibrous (interosseous) membrane is attached, by which the bone becomes attached to another bone. See: interosseous border of fibula, interosseous border of radius, interosseous border of tibia, interosseous border of ulna. Synonym: margo interosseus, interosseous crest, interosseous margin.

| interosseous membrane of forearm | The dense membrane that connects the interosseous margins of the radius and ulna, forming the radioulnar syndesmosis, and with the bones separating the flexor and extensor compartments of the forearm. Synonym: membrana interossea antebrachii. (05 Mar 2000) |
| interosseous membrane of leg | The dense fibrous layer that connects the interosseous margins of the tibia and fibula, forming the upper portion of the tibiofibular syndesmosis and, with the bones and intermuscular septa, creating anterior and posterior comparments of the leg. Synonym: membrana interossea cruris, ligamentum tibiofibulare medium. (05 Mar 2000) |
| interosseous metacarpal ligaments | Fibrous bands connecting the bases of metacarpals two to five; they extend between the dorsal and palmar metacarpal ligaments. Synonym: ligamenta metacarpalia interossea. (05 Mar 2000) |
| interosseous metacarpal spaces | The spaces between the metacarpal bones in the hand. Synonym: spatia interossea metacarpi. (05 Mar 2000) |
| interosseous metatarsal ligaments | Fibrous bands that connect the bases of the metatarsals; they extend between the dorsal and plantar metatarsal ligaments. Synonym: ligamenta metatarsalia interossea. (05 Mar 2000) |
| interosseous metatarsal spaces | The spaces between the metatarsal bones in the foot. Synonym: spatia interossea metatarsi. (05 Mar 2000) |
| interosseous muscles | Muscles which arise from and run between the long (metacarpal and metatarsal) bones of the hand and foot, extending to and producing movement of the digits. See: dorsal interosseous muscles of foot, dorsal interosseous muscles of hand, palmar interosseous muscle, plantar interosseous muscle. Synonym: musculi interossei. (05 Mar 2000) |
| interosseous nerve of leg | <anatomy, nerve> A nerve given off from one of the muscular branches of the tibial nerve which passes down over the posterior surface of the interosseous membrane supplying it and the two bones of the leg. Synonym: nervus interosseus cruris, interosseous nerve of leg. (05 Mar 2000) |
| interosseous sacroiliac ligaments | Short obliquely directed fibrous bands that pass between the sacrum and ilium in the narrow cleft behind the auricular surfaces of these bones. Synonym: ligamenta sacroiliaca interossea. (05 Mar 2000) |
| interosseous talocalcaneal ligament | <anatomy> A strong fibrous band occupying the tarsal sinus. Synonym: ligamentum talocalcaneare interosseum. (05 Mar 2000) |
| interosseous tibiofibular ligament | <anatomy> The distal continuation of the interosseous membrane forming a strong ligament that unites the distal end of the tibia and fibula; it lies deep to the posterior tibiofibular ligament. Synonym: interosseous tibiofibular ligament. (05 Mar 2000) |
| accessory plantar ligaments | The counterparts in the foot of the palmar ligaments in the hand. Synonym: ligamenta plantaria, accessory plantar ligaments, Cruveilhier's ligaments, glenoid ligament. (05 Mar 2000) |
| medial plantar artery | <anatomy, artery> One of the terminal branches of the posterior tibial; distribution, medial side of the sole of the foot; anastomoses, dorsalis pedis, lateral plantar. Synonym: arteria plantaris medialis. (05 Mar 2000) |
| medial plantar nerve | <anatomy, nerve> One of the two terminal branches of the tibial nerve; it courses along the medial aspect of the sole to supply the abductor hallucis and flexor digitorum brevis and, by way of common and proper digital branches, to innervate the skin of the medial part of the foot and medial three and one-half toes. Synonym: nervus plantaris medialis. (05 Mar 2000) |
