(fleks'ŏr dij-i-tō'rŭm sū'pĕr-fish-ē-ā'lis mŭs'ĕl)
Origin, humeroulnar head from the medial epicondyle of the humerus, the medial border of the coronoid process, and a tendinous arch between these points, radial head from the oblique line and middle third of the lateral border of the radius; insertion, by four split tendons, passing to either side of the profundus tendons, into sides of middle phalanx of each finger; action, flexes proximal interphalangeal joint of the fingers; nerve supply, median.
Synonym(s): musculus flexor digitorum superficialis [TA] , superficial flexor muscle of fingers.

There are four tendons of the flexor digitorum superficialis muscle going to fingers 2-5, responsible for flexing the middle joint of the fingers (Figure 1A), four tendons of the flexor digitorum profundus muscle also going to fingers 2-5 responsible for flexing the distal joint of the fingers (Figure 1B), and one tendon from the flexor pollicus longus muscle going to the thumb to flex the thumb (Figure 1C).
