The cranial vault is formed by the frontal, parietal, occipital, and temporal bones, and the greater wings of the sphenoid bone.
A vertical portion, which corresponds to the forehead, and an horizontal portion which is part of the skull base, forming the roofs of the orbital and nasal cavities.
The two parietal bones form the sides and roof of the cranium.
The occipital bone forms the postero-lateral and posterior part of the cranial vault, more than the floor of the posterior skull base. It contains a central large oval opening, the foramen magnum.
The temporal bone has a petrous portion (part of the skull base), a lateral squama (forming the lateral cranial vault) and a mastoid portion.
Unpaired bone, of which the two lateral greater wings contribute to the formation of the anterior lateral cranial vault.
