ra·di·al nerve

[TA]
arises from the posterior cord of the brachial plexus conveying fibers from all roots of the plexus; it curves around the posterior surface of the humerus and passes down to the cubital fossa where it divides into its two terminal branches, the cutaneous superficial and the motor deep; it supplies the muscles of the posterior compartments of the arm and forearm and overlying skin. The radial nerve is most commonly injured by fractures of the middle third of the humerus, resulting in a loss of extension at the wrist ("wrist drop").

radial nerve

the largest branch of the brachial plexus, arising on each side as a continuation of the posterior cord. It supplies the skin of the arm and forearm and their extensor muscles. The branches of the radial nerve are the medial muscular branches, the posterior brachial cutaneous nerve, the posterior muscular branches, the posterior antebrachial cutaneous nerve, the lateral muscular branches, the superficial branch, and the deep branch. Also called musculospiral nerve. Compare median nerve, musculocutaneous nerve, ulnar nerve.
