The cast is applied with the distal fragment in palmar flexion and ulnar deviation. From the deep palmar arch emerge palmar metacarpal arteries. The palmar interossei are supplied by the palmar metacarpal artery of the deep palmar arch. It is supplied by the palmar metacarpal artery of the deep palmar arch. They can sometimes occur on the thicker palmar or plantar skin surfaces. The first palmar interosseous is located at the thumb's medial side. They each receive a contribution from a palmar metacarpal artery. It can also be palpated in the volar (palmar) hand/wrist. It is the natural reaction of the palmar or plantar skin. Moreover, differential placing of flexion creases is a factor in palmar digit ratio. The underlying mechanism involves the formation of abnormal connective tissue within the palmar fascia. The opponens pollicis receives its blood supply from the Superficial palmar arch. A non-slip handle accommodates people with palmar hyperhidrosis. There are two RUL's, the palmar and dorsal radioulnar ligaments. The superficial palmar arch extends more distally than the deep palmar arch.
