| tuberosity of first metatarsal | A tubercle at the base of the bone to which is attached the tendon of the peroneus longus muscle. Synonym: tuberositas ossis metatarsalis primi. (05 Mar 2000) |
|---|---|
| tuberosity of cuboid bone | A slight eminence on the lateral surface of the cuboid bone, capped with an articular facet for a sesamoid bone in the tendon of the peroneus longus muscle. Synonym: tuberositas ossis cuboidei. (05 Mar 2000) |
| tuberosity of navicular bone | A rounded eminence on the medial surface of the navicular bone, giving attachment to a part of the tendon of the tibialis posterior muscle. Synonym: tuberositas ossis navicularis, scaphoid tuberosity. (05 Mar 2000) |
| first cuneiform bone | The largest of the three cuneiform bones, the medial bone of the distal row of the tarsus, articulating with the intermediate cuneiform, navicular, and first and second metatarsal bones. Synonym: os cuneiforme mediale, first cuneiform bone, wedge bone. (05 Mar 2000) |
| anterior carpal region | The anterior part of the wrist. Synonym: regio carpalis anterior. (05 Mar 2000) |
| palmar carpal branch of radial artery | <anatomy, artery> A small branch of the radial artery that passes medially across the wrist to supply the carpal joints; it anastomoses with the anterior carpal branch of the ulnar artery. Synonym: ramus carpalis palmaris arteriae radialis, ramus carpeus palmaris arteriae radialis. (05 Mar 2000) |
| palmar carpal branch of ulnar artery | <anatomy, artery> A branch of the ulnar artery that supplies the carpal joints and communicates with the anterior carpal branch of the radial artery. Synonym: ramus carpalis palmaris arteriae ulnaris, ramus carpeus palmaris arteriae ulnaris. (05 Mar 2000) |
| palmar carpal ligament | Thickening of distal antebrachial fascia just proximal to radiocarpal (wrist) joint. Continuous with extensor retinaculum at margins of forearm. This structure is distinct from the transverse carpal ligament, commonly called "the flexor retinaculum," which forms the roof of the carpal tunnel. Synonym: flexor retinaculum of forearm, palmar carpal ligament. (05 Mar 2000) |
| carpal | Relating to the carpus. (05 Mar 2000) |
| carpal arches | Two anastomotic arterial twigs running transversely across the wrist: the palmar or anterior lies in front of the carpus, being formed by palmar carpal branches of the radial and ulnar arteries; the dorsal or posterior lies on the dorsal surface of the carpus, being formed by the dorsal carpal branches of the radial and ulnar arteries. (05 Mar 2000) |
| carpal artery | <anatomy, artery> Arteries related to and supplying the wrist joint. See: dorsal carpal branch of radial artery, dorsal carpal branch of ulnar artery, palmar carpal branch of radial artery, palmar carpal branch of ulnar artery. (05 Mar 2000) |
| carpal articular surface of radius | The biconcave distal surface of the radius for articulation with the scaphoid bone laterally and the lunate medially. Synonym: facies articularis carpi radii. (05 Mar 2000) |
| carpal articulation | The synovial joint between the distal end of the radius and its articular disk and the proximal row of carpal bones with the exception of the pisiform bone. Synonym: articulatio radiocarpea, carpal articulation, carpal joints, radiocarpal articulation, radiocarpal joint. (05 Mar 2000) |
| carpal bones | Eight bones arranged in two rows that articulate proximally with the radius and indirectly with the ulna, and distally with the five metacarpal bones; in domestic mammals, the bones of the proximal row are called radial, intermediate, ulnar, and accessory, while those of the distal row are termed first, second, third, and fourth carpal bones. Synonym: carpus, ossa carpi. (05 Mar 2000) |
| carpal canal | The passageway deep to the transverse carpal ligament between tubercles of the scaphoid and trapezoid bones on the radial side and the pisiform and hook of the hamate on the ulnar side, through which the median nerve and the flexor tendons of the fingers and thumb pass; compression of the median nerve may occur here (carpal tunnel syndrome). Synonym: canalis carpi, carpal canal. (05 Mar 2000) |
