💪 Understanding the Rotator Cuff: The Key to Shoulder Stability 💪 The rotator cuff is a group of four muscles and their tendons that surround the shoulder joint, providing the stability and movement essential for daily activities. These muscles—supraspinatus, infraspinatus, teres minor, and subscapularis—work together to keep the head of the humerus firmly within the shallow socket of the shoulder. Whether you’re lifting, throwing, or reaching, your rotator cuff is hard at work. #RotatorCuff #
