Deep palmar arch

Arcus palmaris profundus

Definition

The deep palmar arch (arcus volaris profundus; deep palmar arch) is formed by the anastomosis of the terminal part of the radial artery with the deep pallmar branch of the ulnar. It lies upon the carpal extremities of the metacarpal bones and on the Interossei, being covered by the Adductor pollicis obliquus, the Flexor tendons of the fingers, and the Lumbricales. Alongside of it, but running in the opposite direction—that is to say, toward the radial side of the hand—is the deep branch of the ulnar nerve.
