Differentiation by the membrane enclosing the bones

Only the teeth are bare — in that portion which protrudes above the gums. The other bones are entirely covered and hidden before dissection. At the point where they protrude, the teeth lack the covering membrane, like the interior surface of the skull where the cerebrum is contained; a hard membrane [dura mater] clothes the cerebrum and closely surrounds it; elsewhere, the previously named membrane [periosteum] completely encloses the bones except in those places where they are articulated with each other [articulationes cartilagineae, a. synoviales] or are otherwise joined [articulationes fibrosae]. 29
