Nerves of the Anterior & Posterior Compartments of the Arm
|There are three nerves that enter the anterior compartment: 1) musculocutaneous, 2) median and 3) ulnar. The musculocutaneous nerve is the nerve that supplies the 3 muscles of this compartment but the other 2 nerves are merely passing through to perform their functions in the forearm and hand.
||The posterior compartment of the arm is supplied by the radial nerve. It then continues into the posterior group of forearm muscles to supply them.
