The Flexor Digitorum Profundus (pronounced: flex-or di-gi-tor-um pro-fun-dus) is a muscle in the forearm that flexes the fingers (also known as digits). It is considered one of the most powerful flexors of the hand.
Etymology
The term "Flexor Digitorum Profundus" is derived from Latin. "Flexor" refers to a muscle that flexes a joint, "Digitorum" is the plural of "digitus" meaning finger, and "Profundus" means deep, referring to its position underneath the Flexor Digitorum Superficialis.
Anatomy
The Flexor Digitorum Profundus originates from the upper 3/4 of the anterior and medial surfaces of the ulna, interosseous membrane, and deep fascia of the forearm. It runs down the forearm, crosses the wrist, and inserts into the base of the distal phalanges of the four fingers.
Function
The primary function of the Flexor Digitorum Profundus is to enable flexion of the fingers. It also assists in flexing the wrist.
