Muscles and tendons of the shoulder. Middle glenohumeral ligament anterior glenoid cavity lesser tubercle of humerus stabilise the glenohumeral joint limit lateral rotation and extension of joint. The glenohumeral joint consists of an articulation between the scapula and humerus.

Coracohumeral ligament attaches the base of the coracoid process to the greater tubercle. Shoulder ligaments labrum bursae and the joint capsule. The relative weakness of the capsule itself coupled with the bony structure of the glenohumeral joint means that the rotator cuff muscles are largely.

Ligaments glenohumeral ligaments superior middle and inferior the joint capsule is formed by this group. Abduction abduction requires external rotation to clear the greater tuberosity from impinging on the acromion.
