Musculus flexor digitorum profundus

The video tutorial explains the flexor digitorum profundus muscle, one of the three deep flexors of the forearm. It details the muscle's anatomy, including its origin on the ulna and interossea membrane, and its tendons that pass through the carpal tunnel. The muscle is innervated by the median and ulnar nerves. Its primary function is to flex the fingers and hand, with flexion occurring at various joints.
