Superficial Palmar Arterial Arch

Last updated: Jul 2nd, 2025

The superficial palmar arterial arch is usually formed by the deep palmar branch of the ulnar artery joining another branch that descends from the radial artery. The superficial arch curves across the palm and lies distally in the lower part of the hand, above the fingers. It is covered with skin, muscles and nerves. This arch gives rise to three common palmar digital arteries.
