Origin

The ulnar nerve gives off an articular branch to the elbow joint, which relays sensory information to C8 and T1 segments of the spinal cord.

Course

After the ulnar nerve passes through the ulnar groove on the medial epicondyle of the humerus, it gives off a small articular branch to the elbow joint. This branch is usually proximal to the muscular branch of the ulnar nerve to flexor carpi ulnaris (Doyle and Botte, 2003).

Branches

There are no named branches.

Supplied Structures

The articular branch of ulnar nerve provides sensory innervation to the elbow joint.
