extensors of the forearm are found in what compartment
The posterior compartment of the forearm (or extensor compartment) contains 12 muscles which are chiefly responsible for extension of the wrist and digits, and supination of the forearm. It is separated from the anterior compartment by the interosseous membrane between the radius and ulna.uscles [edit]. There are generally 12 muscles in the posterior compartment of the forearm, which can be divided further into the superficial, the intermediate and the deep layer.
