Document Summary

Children have slightly more bones than adults; they fuse as we grow: axial skeleton. Bones protect central nervous system and organs in thoracic: appendicular skeleton. Girdles are the points of attachment of the limbs to the axial skeleton. Pectoral girdle (shoulder girdle) consists of scapula and clavicle. Sternoclavicular joint: this is the only bone-y connection between the pectoral girdle and the axial skeleton. All the rest of the bones are only held in place with ligaments and muscle which gives the upper body a large range of motion. Acromioclavicular joint (on the acromion process): the scapula held in place by muscle so it floats n posterior surface of thorax. Glenohumeral joint (head of humerus articulates with glenoid cavity on scapula. The scapula anterior and posterior view the scapula is a triangular flat bone that is located in the upper back region. The pelvic girdle and lower limb attachment occurs at the pelvic girdle or hip girdle.
