Medical Term:

anterior compartment of forearm

Definition

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.

Synonym(s): compartimentum antebrachii anteriusTA, compartimentum antebrachii flexorum, flexor compartment of forearm
