| extensor carpi radialis longus | <anatomy, muscle> Origin, lateral supracondylar ridge of humerus; insertion, back of base of second metacarpal bone; action, extends and deviates wrist radialward; nerve supply, radial. Synonym: musculus extensor carpi radialis longus, long radial extensor muscle of wrist. (05 Mar 2000) |
|---|---|
| extensor carpi ulnaris | <anatomy, muscle> Origin, lateral epicondyle of humerus (humeral head) and oblique line and posterior border of ulna (ulnar head); insertion, base of fifth metacarpal bone; action, extends and abducts wrist ulnarward; nerve supply, radial (posterior interosseous). Synonym: musculus extensor carpi ulnaris, ulnar extensor muscle of wrist. (05 Mar 2000) |
| facies articularis carpi radii | 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) |
| flexor carpi radialis | <anatomy, muscle> Origin, common flexor origin of the medial condyle of humerus; insertion, anterior surface of the base of the second and most often sending a slip to that of the third metacarpal bone; action, flexes and abducts wrist radialward; nerve supply, median; its tendon travels in its own canal roofed by a layer of the transverse carpal ligament. Synonym: musculus flexor carpi radialis, radial flexor muscle of wrist. (05 Mar 2000) |
| flexor carpi ulnaris | <anatomy, muscle> Origin, humeral head from medial condyle of humerus, ulnar head from olecranon and upper three-fifths of posterior border of ulna; insertion, pisiform bone, but is continued to the fifth metacarpal bone via the pisometacarpal ligament; action, flexes and abducts wrist ulnarward; nerve supply, ulnar. Synonym: musculus flexor carpi ulnaris, ulnar flexor muscle of wrist. (05 Mar 2000) |
| ligamentum carpi dorsale | A strong fibrous band formed as a thickening of the antebrachial deep fascia, stretching obliquely across the back of the wrist, attaching deeply to ridges on the dorsal aspect of the radius, triquetral and pisiform bones, binding down the extensor tendons of the fingers and thumb. Synonym: retinaculum extensorum, dorsal carpal ligament, ligamentum carpi dorsale. (05 Mar 2000) |
| ligamentum carpi radiatum | The ligament that extends from the capitate bone to the scaphoid, lunate, and triquetrum on the palmar side of the wrist. Synonym: ligamentum carpi radiatum. (05 Mar 2000) |
| ligamentum carpi transversum | <anatomy> A strong fibrous band crossing the front of the carpus and binding down the flexor tendons of the digits and the flexor carpi radialis tendon and the median nerve; in so doing it creates the carpal tunnel. Synonym: retinaculum flexorum, deep part of flexor retinaculum, flexor retinaculum, ligamentum carpi transversum, ligamentum carpi volare, volar carpal ligament. (05 Mar 2000) |
| ligamentum carpi volare | <anatomy> A strong fibrous band crossing the front of the carpus and binding down the flexor tendons of the digits and the flexor carpi radialis tendon and the median nerve; in so doing it creates the carpal tunnel. Synonym: retinaculum flexorum, deep part of flexor retinaculum, flexor retinaculum, ligamentum carpi transversum, ligamentum carpi volare, volar carpal ligament. (05 Mar 2000) |
| ligamentum collaterale carpi radiale | The ligament that extends distally from the styloid process of the radius to the carpal bones. Synonym: ligamentum collaterale carpi radiale, external collateral ligament of wrist, lateral ligament of wrist. (05 Mar 2000) |
| ligamentum collaterale carpi ulnare | A ligament that passes from the styloid process of the ulna to the pisiform and triquetrum. Synonym: ligamentum collaterale carpi ulnare, internal collateral ligament of the wrist, medial ligament of wrist. (05 Mar 2000) |
