Verified step by step guidance

Understand the anatomy of the rotator cuff, which is a group of muscles and their tendons that act to stabilize the shoulder.

Identify the four muscles that make up the rotator cuff: Supraspinatus, Infraspinatus, Teres Minor, and Subscapularis.

Recognize that the Teres Major is not part of the rotator cuff. It is a muscle of the upper limb that helps in the movement of the shoulder but is not involved in the stabilization of the shoulder joint like the rotator cuff muscles.

Review the functions of each rotator cuff muscle: Supraspinatus assists in abduction of the arm, Infraspinatus and Teres Minor assist in external rotation, and Subscapularis assists in internal rotation.

Conclude that the Teres Major, which primarily assists in adduction and medial rotation of the arm, is not a rotator cuff muscle.
