The appendicular skeleton consists of the bones of the pectoral (shoulder) girdle, pelvic (hip) girdle, arms, legs, hands, and feet.
There are two bones in the pectoral girdle: the scapula (shoulder blade) and the clavicle (collarbone). Each scapula is flat and has two large processes: the acromion and the coracoid. The acromion connects with the clavicle and the coracoid is an attachment point for several upper limb muscles.
The clavicle has a sternal end that connects to the manubrium of the sternum and an acromial end, which articulates with the scapula to create the shoulder.
