Answer
brachial plexus; median, musculotaneous, ulnar nerves
Work Step by Step
musculotaneous nerve: Distal to the elbow, it provides cutaneous sensation in the lateral forearm.
ulnar nerve: It goes down along the medial aspect of the arm toward the elbow, swings behind the medial epicondyle, and then follows the ulna along the medial forearm
radial: This nerve wraps around the humerus, and then runs anteriorly around the lateral epicondyle at the elbow.
