| common palmar digital nerves | Four nerves in the palm that send branches (proper palmar digital nerves) to adjacent sides of two digits; three are branches of the median, one is from the ulnar. Synonym: nervi digitales palmares communes. (05 Mar 2000) |
|---|---|
| proper palmar digital artery | <anatomy, artery> Terminal branches of the common palmar digital artery that pass to the side of each finger. Synonym: arteria digitalis palmaris propria, collateral digital artery, digital collateral artery. (05 Mar 2000) |
| proper palmar digital nerves | The palmar nerves of the digits of the hand derived from common palmar digital nerves; each nerve supplies a palmar quadrant of a digit and a part of the dorsal surface of the distal phalanx. Synonym: nervi digitales palmares proprii. (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 venous arch | The venous arch accompanying the superficial palmar arterial arch it consists usually of paired venae comitantes and is drained by the superficial ulnar and radial veins. Synonym: arcus venosus palmaris superficialis. (05 Mar 2000) |
| lateral central palmar space | The more lateral (radial) of the central palmar spaces, bounded laterally by the thenar compartment; related distally to the synovial tendon sheath of the index finger and proximally to the common flexor sheath. Synonym: lateral midpalmar space. (05 Mar 2000) |
| long palmar muscle | <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) |
| anterior deep cervical lymph nodes | The lymph nodes near the larynx, trachea, and thyroid gland. Synonym: nodi lymphatici cervicales anteriores profundi. (05 Mar 2000) |
| rapture of the deep | See: nitrogen narcosis. (05 Mar 2000) |
| preauricular deep parotid lymph nodes | Small lymph nodes located deep to the parotid fascia and in front of the ear. Synonym: preauricular deep parotid lymph nodes. (05 Mar 2000) |
| skin-deep | Not deeper than the skin; hence, superficial. Source: Websters Dictionary (01 Mar 1998) |
| small deep petrosal nerve | <anatomy, nerve> One of two sympathetic branches from the internal carotid plexus to the tympanic plexus. Synonym: nervus caroticotympanicus, small deep petrosal nerve. (05 Mar 2000) |
| superficial layer of deep cervical fascia | The part of the cervical fascia investing the sternocleidomastoid and trapezius muscles and completely encircling the neck. Synonym: lamina superficialis fasciae cervicalis, investing fascia, superficial layer of deep cervical fascia. (05 Mar 2000) |
