The palmar arch, as its name implies, crosses the palm of the hand. There are two branches: a superficial and a deep. The deep palmar arch is formed by the continuation of the radial artery and a branch of the ulnar artery. It supplies the palm of the hand, principally the deep muscles of the hand, thumb, and index finger. The superficial palmar arch is a continuation of the ulnar artery and connects with the radial artery supplying the carpal extremities of the metacarpal bones (the fingers). Research Palmar Arch
