Which four muscles and tendons are part of the rotator cuff in the shoulder?

The rotator cuff consists of four specific muscles and their corresponding tendons that play a crucial role in shoulder stability and movement. The correct answer includes the Subscapularis, Infraspinatus, Teres Minor, and Supraspinatus, which are the key components of the rotator cuff.

The Subscapularis is located on the anterior surface of the scapula and is responsible for internal rotation of the humerus. The Infraspinatus is situated on the posterior aspect, helping with external rotation, while the Supraspinatus, located on the superior aspect, initiates shoulder abduction. The Teres Minor, also on the posterior surface, assists with external rotation. Together, these muscles work to stabilize the shoulder joint, allowing for a wide range of motions while simultaneously maintaining shoulder integrity.

Understanding the anatomy and function of these muscles is essential in diagnosing and treating shoulder injuries, as the rotator cuff is often subject to strain, tears, and other conditions that can impact shoulder functionality. The incorrect choices mentioned muscles that are either not part of the rotator cuff or are not among the principal tendons associated with these four key muscles.
