  2. 一、The joint of upper limb

  3. Sternal end of clavicleClavicular notch of sternum （一）The joints of shoulder girdle 1、Sternoclavicular Joint： Composition: Characteristic： ， articular disc Articular disc

  4. （一）The joints of shoulder girdle Movements: forwards and backwards (20-30°) elevation and depression (60°) circumduction

  5. coracoacromial lig. coracoid process Acromion Coracoacromial Ligament acromion coracoid process 2、Acromioclavicular Joint Composition: 3、Coracoacromial Ligament Coracoacromial arch：

  6. （二）The joints of free upper limb Glenoid cavity Head of humorus 肱骨头 1、 Shoulder Joint head of humerus glenoid cavity of scapula Composition： Characteristic：

  7. Accessory structures • Glenoid labrum : • Coracohumeral ligament

  8. Movements: flexion and extention, adduction , abduction, medial and lateral rotation, circumduction

  9. 2、 Elbow Joint Composition: ① Humeroulnar joint ： formed by trochlear of humerus and troclear noch ② Humeroradial joint ： formed by capitulum of humerus and head of radius ③ Proximal radioulnar joint：formed by articular circumference of radius and radial notch of ulna

  10. Radial collacteral ligament Ulnar collacteral ligament Annular ligament of radius Character: ①capsule: ②ligament： Radial collacteral ligament 、 Ulnar collacteral ligament 、 Annular ligament of radius

  11. Movements: flexion and extension,pronation supination
