Protecting the brain, made up of the cerebrum, cerebellum, and brain stem, is the primary function of the cranium. It also provides a platform for the facial muscles to adhere to. No movement or activity occurs within the cranium.
The cranial nerves emerge from the skull through openings in the cranial bones. The ability to smell, see and chew depends on these nerves for effective functioning. For instance, the hypoglossal nerve regulates the tongue’s movements so that we can talk and chew.
The head and face are the two primary parts of the skull. They are recognised by the anatomical and developmental terms neurocranium and viscerocranium, respectively.
