The skull is a bone structure that fixes and protects the human brain. The bones of the skull (except the mandible) are joined together by immovable joints.

The skull is divided into the viscerocranium and the neurocranium. The viscerocranium consists of mandible, maxilla, vomer, inferior nasal concha, ethmoid, hyoid, lacrimal, temporal, nasal, palatine bones and the pterygoid process of the sphenoid bone. The neurocranium

is comprised of the cribriform plate of the ethmoid bone, frontal, occipital, parietal bones and the perous and squamos parts of the temporal bone. In addition to protecting the brain, the skull bones are needed to fix the eyeballs, teeth, nose, ears, and the chewing muscles.
