Skull

Generality

The skull is the set of bones that form the head of the human skeleton.
According to anatomists, it has two distinct main regions: the neurocranium and the splanchnocranium.

The neurocranium has 8 bones. These bony elements form the so-called cranial vault, in which the brain and some sense organs reside, and the so-called base of the skull, which acts as a support for the aforementioned cranial vault. Some bones of the neurocranium are even, others are uneven.
The splanchnocranium is home to 14 bones. These make up the face, therefore also the nasal cavities, the orbital cavities and the mouth. Also in the splanchnocranium there are the even and unequal bone elements.
The bones of the skull mainly serve to protect the various brain structures (brain, diencephalon, cerebellum and brainstem) and the sense organs included in the cranial vault.

So is the skull

The skull is the bony structure that makes up the head of the human skeleton.
Thus, it includes both the bones that house the brain and the bones that make up the face.
