The
anterior compartment of the forearm (or
flexor compartment) contains the following muscles:
The muscles are largely involved with
flexion and
pronation. The superficial muscles have their origin on the
common flexor tendon. The
ulnar nerve and
artery are also contained within this compartment. The flexor digitorum superficialis lies in between the other four muscles of the superficial group and the three muscles of the deep group. This is why it is also classified as the intermediate group.
