The anterior compartment of the forearm contains the following muscles:

Level Muscle E/I Nerve
superficial flexor carpi radialis E median
superficial palmaris longus E median
superficial flexor carpi ulnaris E ulnar
superficial pronator teres I median
superficial (or intermediate) flexor digitorum superficialis E median
deep flexor digitorum profundus E ulnar + median
deep flexor pollicis longus E median
deep pronator quadratus I median
  • "E/I" refers to "extrinsic" or "intrinsic".

The muscles are largely involved with flexion and pronation. The superficial muscles have their origin on the common flexor tendon.
