<Tr> <Td_colspan="2"> Anatomical terms of bone (edit on Wikidata) </Td> </Tr> <P> The shoulder girdle or pectoral girdle is the set of bones in the appendicular skeleton which connects to the arm on each side . In humans it consists of the clavicle and scapula; in those species with three bones in the shoulder, it consists of the clavicle, scapula, and coracoid . Some mammalian species (such as the dog and the horse) have only the scapula . </P> <P> The pectoral girdles are to the upper limbs as the pelvic girdle is to the lower limbs; the girdles are the parts of the appendicular skeleton that anchor the appendages to the axial skeleton . </P> <P> In humans, the only true anatomical joints between the shoulder girdle and the axial skeleton are the sternoclavicular joints on each side . No anatomical joint exists between each scapula and the rib cage; instead the muscular connection or physiological joint between the two permits great mobility of the shoulder girdle compared to the compact pelvic girdle; because the upper limb is not usually involved in weight bearing, its stability has been sacrificed in exchange for greater mobility . In those species having only the scapula, no joint exists between the forelimb and the thorax, the only attachment being muscular . </P>
