11/1/2023 0 Comments Forearm compartmentsThe deep fascia of the forearm encircles the musculature related to the ulna and radius. Fascial layers define the boundaries of these compartments within the forearm. Deep CompartmentThe forearm muscles are broadly divided into two compartments: the anterior flexor compartment and the posterior extensor compartment. It has two heads, which arise from the medial epicondyle of the humerus and the shaft of the radius. In this article, we shall look at the anatomy of the muscles in the anterior compartment of the forearm - their attachments, actions, innervation and clinical correlations. They are mostly innervated by the median nerve (except for the flexor carpi ulnaris and medial half of flexor digitorum profundus, which are innervated by the ulnar nerve), and they receive arterial supply from the ulnar artery and radial artery This muscle group is associated with pronation of the forearm, flexion of the wrist and flexion of the fingers.
