Flexor digitorum superficialis

Origin	Median epicondyle of the humerus (common flexor tendon) as well as parts of the radius and ulna
Insertion	Phalanges
Action(s)	Flexor of fingers (primarily at proximal interphalangeal joints)
Nerve Supply	Median nerve
Arterial Supply	Ulnar artery
Physical Exam	Enter physical examination maneuvers for muscle
Clinical Importance	Enter clinical importance of muscle
Disease States	Enter links to pages where muscle involved
Discussion	The primary function of flexor digitorum superficialis is flexion of the middle phalanges of the fingers at the proximal interphalangeal joints, however under continued action it also flexes the metacarpophalangeal joints and wrist joint. To test flexor digitorum superficialis, one finger is flexed at the proximal interphalangeal joint against resistance, while the remaining three fingers are held fully extended (to inactive flexor digitorum profundus).
