Flexor digitorum profundus muscle

This video tutorial explores the flexor digitorum profundus, a deep forearm muscle responsible for flexing the hand and fingers. It details the muscle's origin, insertion, and innervation by the median and ulnar nerves. The tutorial also describes the path of its tendons through the carpal tunnel and their role in joint flexion. The video concludes with a call to explore more anatomy resources on Kenhub.
