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.

9 paź 2023 · The ulnar nerve is one of the three main nerves of the upper limb and plays a critical role in both sensory and motor functions. It arises from the medial cord of the brachial plexus and primarily innervates parts of the forearm and hand.
13 lis 2023 · The important nerves from the brachial plexus that innervate the hand and wrist are the median, ulnar, and radial nerves: The median nerve passes through the carpal tunnel under the flexor retinaculum of the hand and distally divides into recurrent and common palmar digital branches.
The ulnar nerve is formed from roots C8 and T1, it innervates most of the intrinsic muscles of the hand and 2 muscles in the anterior forearm. It provides sensory innervation to the little finger and part of the ring finger, as well as the medial palmar area.
