| palmar ligaments | The fibrocartilaginous plates, one located on the anterior aspect of each metacarpophalangeal and interphalangeal joint, that are firmly attached to the bases of the phalanges and the heads of the next proximal bones; they are grooved to accommodate the long flexor tendons. Synonym: ligamenta palmaria, accessory volar ligaments. (05 Mar 2000) |

| palmar metacarpal artery | <anatomy, artery> One of the three arteries springing from the deep palmar arch and running in the three medial interosseous spaces; they anastomose with the common palmar and dorsal metacarpal arteries. Synonym: arteria metacarpea palmaris, palmar interosseous artery. (05 Mar 2000) |
| 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) |
| palmar radiocarpal ligament | <anatomy> A strong ligament that passes from the distal end of the radius to the proximal row of carpal bones on the anterior surface of the wrist joint. Synonym: ligamentum radiocarpale palmare. (05 Mar 2000) |
| palmar reflex | Flexion of the fingers following tickling of the palm. (05 Mar 2000) |
| palmar surface | The palm or grasping side of the hand. (12 Dec 1998) |
| palmar surface of fingers | The flat of the fingers; the flexor or anterior surface of the fingers. Synonym: facies digitalis ventralis, facies digitalis palmaris, ventral surface of digit. (05 Mar 2000) |
| palmar ulnocarpal ligament | <anatomy> The fibrous band that passes from the ulnar styloid process to the carpal bones. Synonym: ligamentum ulnocarpale palmare. (05 Mar 2000) |
| central palmar space | The more medial of the central palmar spaces, bounded medially by the hypothenar compartment; related distally to the synovial tendon sheaths of digits 3 and 4 and proximally to the common flexor sheath. Synonym: medial midpalmar space, middle palmar space. (05 Mar 2000) |
| middle palmar space | The more medial of the central palmar spaces, bounded medially by the hypothenar compartment; related distally to the synovial tendon sheaths of digits 3 and 4 and proximally to the common flexor sheath. Synonym: medial midpalmar space, middle palmar space. (05 Mar 2000) |
| short palmar muscle | <anatomy, muscle> Origin, ulnar side of central portion of the palmar aponeurosis; insertion, skin of ulnar side of hand; action, wrinkles skin on medial side of palm; nerve supply, ulnar. Synonym: musculus palmaris brevis, short palmar muscle. (05 Mar 2000) |
| superficial palmar (arterial) arch | The arterial arch in the hand located superficial to the long flexor tendons approximately at the level of a line extrapolated across the palm from the distal side of the outstretched thumb. It is formed principally by the termination of the superficial ulnar artery and is usually completed by a communication with the superficial palmar branch of the radial artery. The arch gives rise to the common palmar digital arteries. Synonym: arcus palmaris superficialis, arcus volaris superficialis. (05 Mar 2000) |
| superficial palmar artery | <anatomy, artery> The superficial palmar branch of the radial artery which supplies the thenar muscles then enters the palm to communicate with the superficial palmar arch from the ulnar artery. Synonym: ramus palmaris superficialis arteriae radialis, superficial palmar artery, superficial volar artery, superficialis volae. (05 Mar 2000) |
| superficial palmar branch of radial artery | <anatomy, artery> The superficial palmar branch of the radial artery which supplies the thenar muscles then enters the palm to communicate with the superficial palmar arch from the ulnar artery. Synonym: ramus palmaris superficialis arteriae radialis, superficial palmar artery, superficial volar artery, superficialis volae. (05 Mar 2000) |
