Nerves of th Arm, Forearm, and Hand 3D

  • Musculocutaneous Nerve (C5–C7)

    • * Pierces the coracobrachialis muscle and descends between the biceps and brachialis muscles.
    • * Innervates the flexor muscles of the anterior compartment of the arm.
    • * Continues into the forearm as the lateral antebrachial cutaneous nerve.

 

  • Median Nerve (C5–T1)

    • * Arises from the lateral and medial cords of the brachial plexus, originating in the spinal cord.
    • * Runs down the anteromedial aspect of the arm, and at the elbow, it lies medial to the brachial artery on the brachialis muscle.
    • * Passes through the cubital fossa and enters the forearm between the humeral and ulnar heads of the pronator teres muscle.
    • * Passes between the flexor digitorum superficialis and the flexor digitorum profundus muscles and then becomes superficial by passing between the tendons of the flexor digitorum superficialis and flexor carpi radialis near the wrist.
    • * Innervates all of the anterior muscles of the forearm except the flexor carpi ulnaris and the ulnar half of the flexor digitorum profundus.
    • * Enters the palm through the carpal tunnel deep to the flexor retinaculum, and gives off branches.
