| arteria digitalis palmaris communis | <anatomy, artery> One of three arteries arising from the superficial palmar arch and running to the interdigital clefts where each divides into two proper palmar digital arteries. Synonym: arteria digitalis palmaris communis. (05 Mar 2000) |
| arteria digitalis palmaris propria | <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) |
| arteria metacarpea palmaris | <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.

| 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) |
