branchesmusculocutaneous
Branches musculocutaneous refer to the muscular and cutaneous branches supplied by the musculocutaneous nerve, a component of the brachial plexus. The nerve arises from the lateral cord, carrying fibers from C5 to C7. It travels through the coracobrachialis muscle, often piercing it, and then descends between the biceps brachii and brachialis. Its muscular branches innervate the three main anterior arm muscles: coracobrachialis, biceps brachii, and brachialis. In addition to motor branches, the nerve often provides articular (sensory) branches to the shoulder and elbow joints.
The principal cutaneous continuation of the musculocutaneous nerve is the lateral antebrachial cutaneous nerve, which emerges
Anatomical variations are reported, including communications with the median nerve via the lateral root of the
Clinical significance: injury or compression of the musculocutaneous nerve can weaken forearm flexion and supination due
