It is a thick, flat, muscle, seated at the anterior part of the forearm. Its upper extremity, which is simple, arises from the internal condyle of the OS humeri; - from the coronoid process of the ulna, and from the anterior edge of the radius. Its lower extremity divides into four tendons, which slide under the anterior annular ligament of the carpus, and are inserted into the second phalanges of the last four fingers, after having been slit to allow the tendons of the flexor profundus to pass through them. This muscle bends the second phalanges on the first; these on the carpal bones, and the hand on the forearm.
