All of the following are the movements taking place during abduction of shoulder joint, EXCEPT?
Abduction of the shoulder joint is a complex movement in which the arm is carried forwards and laterally in the plane of scapula and then raised until it is directed veically above the shoulder thereby completing a movement of 180 degree. The movement involves not only the shoulder joint but requires the lateral rotation of scapula on the chest wall which is accompanied by associated movements at the sternoclavicular and acromioclavicular joints of the shoulder girdle and elevation of humerus.
Medial rotation of scapula
Axial rotation of humerus at acromioclavicular joint
Elevation of humerus
Movements at clavicular end of sternoclavicular joint
