Anatomical terms of muscle

The flexor digitorum profundus or flexor digitorum communis profundus[1] is a muscle in the forearm of humans 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.[2] The muscle is named from Latin 'deep bender of the fingers'.
