5 lip 2023 · The superficial branch of the ulnar nerve supplies sensory innervation to the anterior aspect of the ulnar 1½ digits (little finger and half of the ring finger) and medial palmar skin. Additionally, it provides motor innervation to the palmaris brevis muscle in the hypothenar region of the hand.
