Origin

The deep palmar branch of the ulnar artery arises from the ulnar artery and anastomoses with the deep palmar arch.

Course

The deep palmar branch arises from the ulnar artery at the base of the fifth metacarpal. It pierces the opponens digiti minimi muscle and courses laterally, deep to the flexor digitorum tendons. It then anastomoses with the deep palmar arch arising from the radial artery.

Branches

There are no named branches.

Supplied Structures

The deep palmar branch of the ulnar artery contributes to the supply of the hypothenar, opponens pollicis, and the interossei muscles, and palmar aspect of the metacarpal and digits via the deep palmar arch (Standring, 2016).
