Calvaria (skull)

The calvaria is the top part of the skull. It is the superior part of the neurocranium and covers the cranial cavity containing the brain. It forms the main component of the skull roof.

The calvaria is made up of the superior portions of the frontal bone, occipital bone, and parietal bones. In the human skull, the sutures between the bones normally remain flexible during the first few years of postnatal development, and fontanelles are palpable. Premature complete ossification of these sutures is called craniosynostosis.

In Latin, the word calvaria is used as a feminine noun with plural calvariae; however, many medical texts incorrectly list the word as calvarium, a neuter Latin noun with plural calvaria.
