The Posterior cord is a division of the brachial plexus.
The posterior cord gives rise to the following nerves:
The radial nerve, which innervates the triceps brachii muscle, the brachioradialis muscle, the extensor muscles of the fingers and wrist (extensor carpi radialis muscle), and the extensor and abductor muscles of the thumb. See radial nerve injuries.
