Pictured above are the biceps muscles. Both of them pull your lower arm toward your shoulder. The deeper of the two biceps muscles (the brachialis) is responsible for 'true flexion' of your elbow, and is involved in EVERY action you do that requires your elbow joint. Issues like golfer's elbow respond well when you reduce excess tension in the brachialis.
The muscles are layered, showing how some of the muscles are covered by the others. All of the muscles are see-through so that you can appreciate the location and size of each muscle relative to the others.
