The median nerve is a bundle of nerve fibers which arises from the lateral and median cords of the brachial plexus. It goes into the arm through the axilla, at the lower border of the teres major muscle, and then it runs down along the inner side of arm, parallel to the brachial artery. Then, it runs into the hand through the carpal tunnel. In the forearm and hand, the median nerve gives off the following branches: the anterior interosseous and common palmar digital nerves, as well as muscular and palmar branches. Made up of both motor and sensitive fibers, the median nerve supply the muscle and skin of the forearm.
