Which of the following best describes the function of the rotator cuff?

The rotator cuff is primarily responsible for stabilizing and moving the shoulder joint. This group of muscles and their associated tendons surrounds the shoulder, providing crucial support for various movements. The rotator cuff consists of four main muscles: the supraspinatus, infraspinatus, teres minor, and subscapularis. Together, they facilitate the stabilization of the humeral head within the shallow glenoid cavity of the scapula while also allowing for a wide range of shoulder movements, including rotation and lifting.

By maintaining the position of the shoulder joint, the rotator cuff helps to prevent dislocations and ensures that the arm can move freely and effectively in various directions. Strengthening and maintaining the integrity of the rotator cuff is vital for athletes and individuals engaging in activities that require overhead motions or repetitive arm movements.
