Chapter 008 The Elbow and Radioulnar Joints

The extension motion of the elbow occurs in only one arm at a time. This is when the arm comes back into the water and fully extends in a line with the torso and is then followed by wrist flexion. The muscles that perform this action are the triceps brachii long head, triceps brachii lateral head, triceps brachii medial head, and the aconeus. ................
