Document Summary

Anatomy 16: bones of the pectoral girdle and upper limb. The upper limb attaches to the axial skeleton through the pectoral girdle. The pectoral girdle attaches to the axial skeleton at the sternoclavicular joint. Thus, this is where the appendicular skeleton attaches to the axial skeleton. The pectoral girdle is composed of the clavicle and the scapula (appendicular skeleton) The sternoclavicular and acromioclavicular joints are synovial (plane) joints based on structure and diarthrotic joints based on function. Within the upper limb, there are 30 bones: Ante brachium > 2 (radius and ulna) At the elbow, the humerus articulates with both the: The radius and th ulna articulate at the: Proximal radioulnar joints (i. e. between the head of the radius and the radial. Distal radioulnar joint (i. e. between the head of ulna articulates with the ulnar notch of the ulna; head held in place by the annular ligament) notch in the distal end of the radius)
