Rotator cuff is a common term used in medicine to describe four muscles that surround the shoulder joint. These muscles are responsible for controlling the movement and stability of the shoulder, which is essential for carrying out daily activities. However, there are also several synonyms for the term rotator cuff, including rotator cuff muscles, rotator cuff tendons, and supraspinatus muscles. Other common synonyms include subscapularis muscle, teres minor muscle, and infraspinatus muscle. These terms are crucial to understanding how the shoulder works and how injuries to the rotator cuff can affect movement and cause pain.
