Answer: C The movement circumduction combines the multiple actions of the four rotator cuff muscles supraspinatus, infraspinatus, teres minor, and subscapularis. Supraspinatus creates the action abduction; subscapularis creates the action medial rotation while the infraspinatus and teres minor create the actions of extension/lateral rotation. Combining these movements in motion is called circumduction (creating a circle or cone-shape). Imagine “winding up” for a baseball pitch.
