anterior compartment of forearm

anterior compartment of forearm

[TA]
anterior portion of the space enclosed by the antebrachial fascia, separated from the posterior compartment by the radius and ulna and by the intervening interosseous membrane; the spaces are demarcated superficially by the subcutaneous border of the ulna and the (pulse of the) radial artery; contains the pronators of the forearm, flexors of the wrist, and long flexors of the digits, innervated by the median (mostly) and ulnar nerves; is unusual among limb compartments because it communicates across the wrist joint via the carpal tunnel with the midpalmar space.

These muscle fibers separated from the lower part of the flexor carpi ulnaris and formed a small muscle belly, which crossed ulnar nerve and vessels, median nerve and ended in a broad aponeurosis which crossed the tendons of flexor digitorum superficialis and merged with the deep fascia and flexor retinaculum (Fig.
