The musculocutaneous nerve is a mixed branch of the lateral cord of the brachial plexus derived from cervical spinal nerves C5-C7. It arises opposite the lower border of the pectoralis minor.[1] It provides motor innervation to the muscles of the anterior compartment of the arm: the coracobrachialis, biceps brachii, and brachialis.[2] It provides sensory innervation to the lateral forearm (via its terminal branch).[3] It courses through the anterior part of the arm, terminating 2 cm above elbow;[citation needed] after passing the lateral edge of the tendon of biceps brachii it is becomes known as the lateral cutaneous nerve of the forearm.[3]
