Muscle Anatomy

flexor digitorum superficialis

There are two major muscles located in the forearm that flex the fingers. They are the flexor digitorum superficialis and the flexor dig!torum profundus. The flexor digitorum superficialis is situated just beneath the flexor carpi radialis and the palmaris longus on the anterior side of the forearm.


It originates on the medial epicondyle of the humerus, the coronoid process of the ulna, and the middle half of the anterior surface of the radius.


Insertion is by four tendons, which separate after passing the wrist and then go to the four fingers (index, middle, ring, and little fingers).
