In Man,as in all other Mammals, the skeleton isprimarily distinguishable into the axialskeleton, or spine, and the skeleton of theappendages, or the bony frame of the spine consists of the vertebral columnand of the skull; the latter being the pecu-liarly modified anterior part of the ribs are the appendages of the vertebralcolumn; the tongue-bone {os lingiice), thelower jaw, and the other products of thegill-arches, are those of the skull. Theskeletons of the two pairs of limbs, or ex-tremities, are composed of two differentparts : of the bony frame of the actual, pro-minent extremities, and of the inner girdleskeleton, by which the limbs are attachedto the vertebral column. The girdle skele-ton of the arms (or fore limbs) is theshoulder girdle; the
