Which muscle group is the rotator cuff composed of?

1. Deltoids

2. Supraspinatus, Infraspinatus, Teres minor, Subscapularis

3. Rhomboids

4. Trapezius

The correct answer is: Supraspinatus, Infraspinatus, Teres minor, Subscapularis

The rotator cuff is composed of four specific muscles: the supraspinatus, infraspinatus, teres minor, and subscapularis. These muscles play a crucial role in stabilizing the shoulder joint and facilitating a range of movements. The supraspinatus is responsible for initiating shoulder abduction, while the infraspinatus and teres minor primarily contribute to external rotation of the shoulder. The subscapularis, on the other hand, is involved in internal rotation. Together, these muscles form a protective cuff around the shoulder joint, helping to keep the humeral head securely positioned within the shallow socket of the scapula. Understanding the distinct roles and functions of these muscles is essential for anyone studying massage therapy, as many clients may seek treatment for issues related to shoulder injuries or conditions that affect the rotator cuff. Recognizing this muscle group assists therapists in providing targeted and effective care.
