The teres minor is a small muscle located on the lateral side of the scapula and is responsible for lateral rotation of the shoulder joint. The pectoralis major is a larger muscle located on the anterior chest wall and is responsible for adduction, flexion, and medial rotation of the shoulder joint. The supraspinatus is a rotator cuff muscle that assists in abduction of the shoulder joint. The teres major is also involved in shoulder movement, but its primary function is extension, adduction, and medial rotation of the shoulder joint.
