Posterior Compartment Of The Forearm
The posterior compartment of the forearm (or extensor compartment) contains twelve muscles which primarily extend the wrist and digits. It is separated from the anterior compartment by the interosseous membrane between the radius and ulna. Structure Muscles There are generally twelve muscles in the posterior compartment of the forearm, which can be further divided into superficial, intermediate, and deep. Most of the muscles in the superficial and the intermediate layers share a common origin which is the outer part of the elbow, the lateral epicondyle of humerus. The deep muscles arise from the distal part of the ulna and the surrounding interosseous membrane. The brachioradialis, flexor of the elbow, is unusual in that it is located in the posterior compartment, but it is actually a muscle of flexor / anterior compartment of the forearm. The anconeus, assisting in extension of the elbow joint, is by some considered part of the posterior compartment of the arm. The majority o ...

Anterior Compartment Of The Forearm
The anterior compartment of the forearm (or flexor compartment) contains the following muscles: The muscles are largely involved with extension and supination. 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.
