While for another celebrity plastic surgery is something to be concealed and denied, Cher herself has admitted to having gone under the knife for multiple surgical procedures during the course of her long career.
1 Pectoralis minor draws the scapula forward and downward, and raises the ribs in forced inspiration. 2  The subclavius muscle is a small muscle that lies deep to pectoralis major muscle. 3  It passes from rib I at the junction between the rib and its costal cartilage to a groove on the inferior (lower) surface of the clavicle. These muscles retract and elevate the scapula. 2  Teres major muscle originates from posterior surface of the inferior angle of the scapula and attaches the medial lip of the intertubercular sulcus which lies on the anterior surface of the humerus. 3  This muscle extends and medially rotates the humerus.
The trapezius, along with the rhomboideus major and minor, and levator scapulae, work together to elevate the shoulder. Scapula adduction, or the act of moving your arm and shoulder backwards, involves the trapezius and the rhomboids. The trapezius also acts in head/neck extension, or the act of tilting your head back.
