located in the same plane

Explanation:

Such types of muscles and tendons that play an important role in the stabilization of the shoulder are called rotator cuff muscle. These muscles are responsible for the different types of motion and simply called a different range of motion. Muscles like scapulohumeral muscles,  infraspinatus muscle and some others are grouped as rotator muscle. These muscles are involved in the movement of the shoulder and also stabilize the joints of the shoulder for the movement and during the movement. When the humeral head is centered within the cavity of the glenoidal then the rotator cuff muscle should be on the same plane.
