Answer
Originates from the medial epicondyle of the humerus, coronoid process of the ulna, and upper half of the radial shaft.
The flexor digitorum superficialis muscle originates from two heads: the humeroulnar head originates at the medial epicondyle of the humerus and the coronoid process of the ulna, while the radial head originates on the upper half of the volar aspect of the radial shaft.
