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.

10 paź 2024 · Innervation of Hand Muscles. The ulnar nerve is significant in the innervation of hand muscles, especially those responsible for intricate movements. Originating from the brachial plexus, it travels through the arm into the hand, innervating several intrinsic muscles crucial for finger movements.
The ulnar nerve innervates most of the intrinsic hand muscles, and provides the sensory innervation to the dorsal and palmar surfaces of the fifth and part of the fourth digits. Finally, the radial nerve does not innervate any muscle in the hand.
