text: The interposition of these girdles adds to the mobility of the extremities, and as the upper extremity is more mobile than the lower we find the shoulder-girdle composed of two bones instead of one as in the pelvic girdle; also, as the lower extremity bears the weight of the body it requires strength in addition to mobility, hence we find that it is joined to the trunk by a single big strong bone, the innominate, instead of by two comparatively slight, narrow bones like the clavicle and scapula which form the shoulder-girdle.
