Anatomy and Cell Biology 3319 Study Guide - Midterm Guide: Flexor Digitorum Profundus Muscle, Carpal Bones, Epicondyle
Document Summary
Lab 13 station 2: muscles of anterior forearm. Note: since all of the four superficial anterior forearm muscles cross the elbow joint and originate from the medial epicondyle of the humerus, all of these muscles may contribute slightly to forearm flexion. F: tightens the palmar aponeurosis, and weak wrist flexor. O: medial epicondyle of the humerus, coronoid process of the ulna, superior anterior radius. F: flexion of pip and metacarpophalangeal joints of the 2nd 5th digits. I admit, this is not the best view of flexor digitorum superficialis.

On a bellringer if this were asked, it would be much more obvious that the muscle is deep to the other muscles surrounding it. O: proximal of anterior/medial ulna and interosseous membrane. N: median nerve (lateral part), and ulnar nerve (medial part)
