The skull consists of 29 bones. These may be considered in 3 functional groups:
1. The cranium
8 bones which enclose and protect the brain
2. The facial bones
14 bones which support the face, bear the teeth, give protection to special sense organs (eye, nose) and provide attachment for muscles that move the jaw.
3. Others
the single hyoid bone which supports the larynx (voice box), and 3 pairs of ear ossicles in the middle ear which transmit sound waves to the inner ear.
