As a muscle of the anterior compartment of the arm, the nerve that innervates it is a branch of which cord of the brachial plexus?

• medial cord, because it's innervated by the ulnar nerve

• lateral cord, because it's innervated by the musculocutaneous nerve

• posterior cord, because it's innervated by the axillary nerve

• posterior cord, because it's innervated by the radial nerve

• both medial and lateral cords, because it's innervated by the median nerve
