| palmaris brevis | <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) |
|---|---|
| palmaris longus | <anatomy, muscle> Origin, medial epicondyle of humerus; insertion, flexor retinaculum of wrist and palmar fascia; action, makes palmar fascia tense and flexes the hand and forearm; is absent about 20% of the time; when tensed, its tendon stands out sharply at the wrist and overlies the median nerve; nerve supply, median. Synonym: musculus palmaris longus, long palmar muscle. (05 Mar 2000) |
| ramus carpalis palmaris arteriae radialis | <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.

| ramus carpalis palmaris arteriae ulnaris | <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) |
| ramus carpeus palmaris arteriae radialis | <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.

| ramus palmaris nervi mediani | <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) |
| ramus palmaris nervi ulnaris | <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) |
| ramus palmaris superficialis arteriae radialis | <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) |
| musculus interosseus palmaris | <anatomy> Three muscles in the hand; origin, first: ulnar side of second metacarpal; second and third: radial sides of fourth and fifth metacarpals; insertion, first: into ulnar side of index; second and third: into radial sides of ring and little fingers; action, adducts fingers toward axis of middle finger; nerve supply, ulnar. See: flexor pollicis brevis muscle. Synonym: musculus interosseus palmaris, musculus interosseus volaris. (05 Mar 2000) |
| musculus palmaris brevis | <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) |
| musculus palmaris longus | <anatomy, muscle> Origin, medial epicondyle of humerus; insertion, flexor retinaculum of wrist and palmar fascia; action, makes palmar fascia tense and flexes the hand and forearm; is absent about 20% of the time; when tensed, its tendon stands out sharply at the wrist and overlies the median nerve; nerve supply, median. Synonym: musculus palmaris longus, long palmar muscle. (05 Mar 2000) |
| pyosis palmaris | An affection observed in children in the East Indies, characterised by the presence of numerous discrete pustules on the palms. Pyosis tropica, an affection seen in Sri Lanka, marked by the presence of dirty yellowish or blackish lesions, covered with a crust, the removal of which leaves a shallow granulating ulcer. Synonym: Kurunegala ulcers. (05 Mar 2000) |
| ichthyosis palmaris et plantaris | The occurrence of symmetrical diffuse or patchy areas of hypertrophy of the horny layer of the epidermis on the palms and soles; a group of ectodermal dysplasias of considerable variety, and either autosomal dominant or recessive inheritance. Synonym: ichthyosis palmaris et plantaris, keratoderma palmaris et plantaris, keratoderma symmetrica, keratoma plantare sulcatum, keratosis palmaris et plantaris, tylosis palmaris et plantaris. (05 Mar 2000) |
| tylosis palmaris et plantaris | The occurrence of symmetrical diffuse or patchy areas of hypertrophy of the horny layer of the epidermis on the palms and soles; a group of ectodermal dysplasias of considerable variety, and either autosomal dominant or recessive inheritance. Synonym: ichthyosis palmaris et plantaris, keratoderma palmaris et plantaris, keratoderma symmetrica, keratoma plantare sulcatum, keratosis palmaris et plantaris, tylosis palmaris et plantaris.
