In human anatomy the flexor digitorum profundus (FDP Latin for deep bender of the fingers) is a muscle in the forearm that flexes the fingers (also known as digits). It is considered an extrinsic hand muscle because it acts on the hand while its muscle belly is located in the forearm.Together the flexor pollicis longus pronator quadratus and flexor digitorum profundus form the deep layer of ventral forearm muscles.
