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.
Function. The pectoralis major muscle is the most important muscle for the adduction and anteversion of the shoulder joint which is why it is also known as the âbreaststroke muscleâ. It rotates the upper arm outwards and makes a powerful stroke movement (retroversion) when the arms are elevated (e.g. in wood-chopping).he pectoralis major muscle (green highlighted on the picture) is a strong, fan-shaped muscle of the shoulder joint. It decisively shapes the surface anatomy of the breast. Furthermore it participates in forming the anterior wall of the axilla.
