![]() These muscles are relatively subcutaneous as there is usually not much subcutaneous fat on the dorsal aspect of the forearm. The superficial group includes the extensor digitorum communis, extensor digiti minimi, extensor carpi ulnaris, and anconeus. The posterior compartment of the forearm is also known as the extensor compartment since the muscles primarily function to extend the wrist and digits of the hand. The posterior compartment of the forearm contains a superficial and deep muscle group. The intermediate compartment contains the flexor digitorum superficially. The deep compartment of the contains the flexor digitorum profundus, flexor pollicis longus, and pronator quadratus. The muscles are separated into deep, intermediate, and superficial groups. The superficial compartment contains the pronator teres, the flexor carpi radialis, and the flexor carpi ulnaris. The anterior compartment contains muscles that act to flex the wrist and digits. The mobile wad consists of three muscles: the brachioradialis, extensor carpi radialis longus, and extensor carpi radialis brevis. The deep group includes the supinator, abductor pollicis longus, extensor pollicis brevis, extensor pollicis longus, and extensor indicia. The muscles are further broken down into deep and superficial groups. The superficial group includes the extensor digitorum communis, extensor digiti minimi, extensor carpi ulnaris, and anconeus. The muscles found in the posterior compartment primarily function to extend the wrists and digits. ![]() The compartments of the forearm are separated by an interosseous membrane found between the radius and ulna in addition to a lateral intermuscular septum. These include the anterior compartment, posterior compartment, and the mobile wad. ![]() It consists of several muscles and an extensive neurovascular network encased in three compartments. ![]() The forearm is the region of the body spanning from the elbow to the wrist. ![]()
