| dental implants, single-tooth | Devices, usually alloplastic, surgically inserted into or onto the jawbone, which support a single prosthetic tooth and serve either as abutments or as cosmetic replacements for missing teeth. (12 Dec 1998) |
| diseases, single-gene | Hereditary disorders caused by a change (mutation) in a single gene. There are thousands of single-gene diseases including achondroplastic dwarfism, Huntington disease, cystic fibrosis, sickle cell disease, Duchenne muscular dystrophy, and haemophilia. Single-gene diseases typically describe classic simple Mendelian patterns of inheritance (as autosomal dominant, autosomal recessive, and X-linked traits) by comparison with polygenic diseases.

| DNA, single-stranded | A single chain of deoxyribonucleotides that occurs in some bacteria and viruses. It usually exists as a covalently closed circle. (12 Dec 1998) |
| palmar | 1. <anatomy> Pertaining to, or corresponding with, the palm of the hand. 2. <ornithology> Of or pertaining to the under side of the wings of birds. Origin: L. Palmaris, fr. Palma the palm of the hand: cf. F. Palmaire. Source: Websters Dictionary (01 Mar 1998) |
| palmar aponeurosis | The thickened, central portion of the fascia ensheathing the hand; it radiates toward the bases of the fingers from the tendon of the palmaris longus muscle. Synonym: aponeurosis palmaris, Dupuytren's fascia, palmar fascia. (05 Mar 2000) |
| palmar branch of median nerve | <anatomy, nerve> Branch of median nerve arising proximal to flexor retinaculum and running superficial to it to supply skin of proximal central palm and thenar eminence. Since it does not traverse carpal tunnel, it is not affected by carpal tunnel syndrome, even though it supplies skin distal to carpal tunnel. Synonym: ramus palmaris nervi mediani. (05 Mar 2000) |
| palmar branch of ulnar nerve | <anatomy, nerve> Branch of ulnar nerve arising in distal forearm and accompanying palmar artery into hand where it supplies skin of little finger and medial half of ring finger and adjacent parts of palm. Synonym: ramus palmaris nervi ulnaris. (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) |
| palmar carpometacarpal ligaments | Fibrous bands that connect the palmar surfaces of the carpal and metacarpal bones. Synonym: ligamentum carpometacarpalia palmaria. (05 Mar 2000) |
| palmar crease | Any of the several flexion crease's normally found on the palm of the hand, occurring proximal to, but as a consequence of flexion at, the metacarpophalangeal joints. (05 Mar 2000) |
| palmar digital veins | Paired venae comitantes of the proper and common digital arteries that empty into the superficial palmar venous arch. Synonym: venae digitales palmares. (05 Mar 2000) |
| palmar fascia | The thickened, central portion of the fascia ensheathing the hand; it radiates toward the bases of the fingers from the tendon of the palmaris longus muscle. Synonym: aponeurosis palmaris, Dupuytren's fascia, palmar fascia. (05 Mar 2000) |
