In other mammalia this aperture lies further back, and takes a more oblique direction, so that the head is thrown forward, and requires to be upheld partly by muscular effort and partly by the ligamentum nuchae, popularly known in cattle as the "pax-wax." Again, the relative lengths of the bones of the hinder extremities in man form an obstacle to his walking on all-fours.
