- Ligament from superior aspect of coracoid process to inferior aspect of clavicle
- Ligament from coracoid process to conoid tubercle on inferior clavicle
- Ligament from glenoid labrum to neck of humerus
- With elevation of the clavicle there is translation in this direction of the sternoclavicular joint
- During flexion and abduction the clavicle rolls superior and...

- This joint has 120 degrees of abduction
- Origin: Ribs 1-8; Insertion: Anterior medial scapula
- Innervates Latissimus dorsi
- Origin: Ligamentum nuchae and SP of C7-T5; insertion: medial scapular border
- Origin: Anterior medial clavicle; Insertion: intertubercular groove of humerus
