The superficial anterior forearm muscles are a group of five muscles located in the anterior flexor compartment of the forearmThese muscles include the pronator teres flexor carpi radialis flexor carpi ulnaris palmaris longus and flexor digitorum superficialis. Ulnae or ulnas is a long bone found in the forearm that stretches from the elbow to the smallest finger and when in anatomical position is found on the medial side of the forearm.
