Musculocutaneous nerve

The musculocutaneous nerve is a mixed nerve that contains both sensory and motor fibers. It usually penetrates the coracobrachialis muscle obliquely and travels between the biceps brachii and brachialis muscles. It burrows through the brachial fascia laterally to the tendon of the biceps brachii above the lateral epicondyle of the humerus, and then continues downward as the lateral antebrachial cutaneous nerve.
