Name the five major nerves that emerge from the brachial
plexus. List the muscles they innervate and the areas of
skin they supply
The five major nerves that emerge from the brachial plexus are the axillary nerve, ulnar nerve, radial nerve, median nerve, and musculocutaneous nerve.
Musculocutaneous nerve: It innervates biceps brachii, coracobrachialis, and brachialis. The area of skin it supplies is the lateral side of the forearm.
Axillary nerve: It innervates the glenohumeral joint, teres minor, and deltoid region. The area of skin it supplies is the superolateral side of the arm
Radial nerve: It innervates tricep brachii and muscles of the forearm. The area of skin it supplies is lateral to axial lines of the hand.
Ulnar nerve: It innervates flexor carpi ulnaris, forearm, and intrinsic muscles of the hand. The area of skin it supplies is medial to axial lines of the hand.
Median nerve: It innervates the muscles of the anterior forearm and intrinsic muscles of the hand's thenar region. The area of skin it supplies is the hand.
