Skull

The skull is the skeleton of the head and face. The skull is made of twenty-nine bones including the mandible, the hyoid bone and the auditory ossicles (ear bones). Twenty-one bones are so firmly knit together that they are taken apart with difficulty; they are built together in such a way that they enclose one large cavity and three smaller ones. The large cavity is called the cranial cavity, and contains the brain and its membranes; the smaller cavities are the cavities of the nose, and the two orbits, which hold the eyeballs. There are lesser cavities contained within certain of the skull-bones; these cavities are the middle-ear, the internal ear, and the air-sinuses. The skull bones consist of two plates or tables of compact substance that enclose a layer of spongy substance between them; in skull-bones this substance is called diploe. In some of them the diploe is absorbed leaving cavities or air-sinuses between the tables of compact bone; the sinuses communicate with the cavity of the nose and have a mucous lining continuous with that of the nose.
