The bony skeleton of the head, which rests on the 1st cervical vertebra. The skull protects the brain, houses the special sense organs, provides points of attachment for muscles, and forms part of the respiratory and digestive tracts.
The 8 bones of the cranium encase the brain.
The skull’s facial skeleton includes the nasal and cheek bones, maxilla, and mandible.
All except the mandible are fixed together by immovable joints.
This is the collection of 22 ?at and irregularly shaped bones which protect the brain and form the face (see BONE).
Arrangement of the bones In childhood, the bones are independent, gradually fusing together by sutures, and in old age fusing completely so that the cranium forms a solid bony case. At the time of birth the growth of several bones of the infant’s head has not been quite completed, so that six soft spots, or fontanellas, present; here the brain is covered only by skin and membranes, and the pulsations of its blood vessels may be seen. One of these spots, the anterior fontanelle, does not close completely until the child is 18 months to 2••• years old.
Parts of the skull The cranium, enclosing the brain, consists of eight bones, while the face, which forms a bony framework for the eyes, nose and mouth, consists of 14 bones. These two parts can be detached.
Shape of the skull The development of large central hemispheres of the brain in humans has in?uenced the skull shape. Unlike in other mammals, the cranium extends above as well as behind the face which therefore looks forwards. The skull’s proportions change with age: the cranium in children is larger in comparison with the face – one-eighth of the whole head – than is the case in adults, where sizes are about the same. Old age reduces the size of the face because of the loss of teeth and absorption of their bony sockets. Women’s skulls tend to be lighter and smoother with less obvious protuberances than those in men.
n. the skeleton of the head and face, which is made up of 22 bones. It can be divided into the cranium, which encloses the brain, and the face (including the lower jaw (mandible). The cranium consists of eight bones. The frontal, parietals (two), occipital, and temporals (two) form the vault of the skull (calvaria) and are made up of two thin layers of compact bone separated by a layer of spongy bone (diploë). The remaining bones of the cranium – the sphenoid and ethmoid – form part of its base. The 14 bones that make up the face are the nasals, lacrimals, inferior nasal conchae, maxillae, zygomatics, and palatines (two of each), the vomer, and the mandible. All the bones of the skull except the mandible are connected to each other by immovable joints (see suture). The skull contains cavities for the eyes (see orbit) and nose (see nasal cavity) and a large opening at its base (foramen magnum) through which the spinal cord passes. See illustration overleaf.
