Description: D i.e. Allows flexion, rotation & abduction * The three joints in shoulder complex are sternoclavicular, acromioclavicular, and gleno- humeral joints.* The glenohumeral joint is a synol ball and socket aiculation between the head of the humerus and glenoid cavity of scapula. It is the most impoant joint of shoulder complexQ. Movements at this joint includes flexion, extension, abduction, adduction, medial rotation, lateral rotation and circumductionQ.* Sternoclavicular & acromioclavicular joints allow movements in antero posterior and veical planes to gether with some axial rotation.* For every 3deg abduction of arm, a 2deg abduction occurs in the shoulder joint, and 1deg occurs by rotation of scapula. At about 120degof abduction, the greater tuberosity of humerus hits the lateral edge of the acromian. Movements of scapula include rotation and anteroposterior glidingQ
