Ulnar nerve anatomy
- The ulnar nerve is formed from the C8 and T1 spinal nerve roots
- It arises from the medial cord of the brachial plexus
- It passes between the triceps and brachialis muscles in the arm
- It traverses the cubital tunnel at elbow
- It then passes between the two heads of flexor carpi ulnaris in the forearm
- It terminally divides into deep motor and superficial sensory branches in the distal forearm
Muscles innervated by the ulnar nerve
