Shoulder Joint is otherwise called a Glenohumeral joint; a ball and socket type of synovial joint with multi-axial movements.
Shoulder joint Movements:
1. Flexion,
2. Extension,
3. Abduction,
4. Adduction,
5. Internal rotation,
6. External rotation,
7. Circumduction
Ligaments of the Shoulder joint:
1. Coracoclavicular ligaments (Between the coracoid process of scapula and clavicle bone)
2. Coracoacromial ligament (Between the coracoid process of scapula and acromion process of scapula)
3. Coracohumeral ligament (Between the coracoid process of scapula and humerus bone)
4. Acromioclavicular ligament (Between acromion process of the scapula and distal end of clavicle bone)
Bursa's in the shoulder:
1. Subdeltoid bursa
2. Subacromial bursa
3. Subcoracoid bursa
4. Subscapular bursa
