The superficial branch of the ulnar nerve supplies the palmaris brevis and the skin on the ulnar side of the hand, and divides into a proper palmar digital nerve for the ulnar side of the little finger, and a common palmar digital nerve which gives a communicating twig to the median nerve and divides into two proper digital nerves for the adjoining sides of the little and ring fingers.

The proper digital branches are distributed to the fingers in the same manner as those of the median nerve.
