axillary nerve
median nerve
musculocutaneous nerve
radial nerve
ulnar nerve
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
