The Deep Muscles Of The Anterior Compartment Of The Forearm

Since we already covered the superficial muscles of the anterior forearm, it's time to get deep and talk about muscles like Flexor digitorum profundus, flexor pollicis longus and pronator quadratus. These also function in flexion of the wrist and pronation of the hand and are mostly innervated by the anterior interosseus nerve, except for Flexor digitorum profundus, which is innervated not only by that nerve, but also the ulnar nerve.
