Skull
Structure of the Skull
The bones of the skull can be divided into two groups: cranium and facial bones. The cranium is composed of 8 bones, which enclose and protect the brain, along with the meninges and cerebral vasculature (blood vessels of the brain). Among these bones are the frontal, temporal, parietal and occipital bones, which correspond to the lobes of the cerebrum.
There are 14 facial bones, which support the soft tissues of the face (eyes, nose, mouth).
The skull has two very important roles. First, it provides structure and support for the head. Second, the skull protects the brain, preventing any injury or harm.
Protecting the Brain
The skull is one of many protective layers of the brain. The skull not only creates a hollow space for the brain to sit in, but it also acts as armor to shield the brain from physical blows.
The next layer of protection is the meninges, which surround the brain and anchor it to the skull. This layer prevents your brain from moving around in your skull.
The last layer of protection is cerebrospinal fluid (CSF), which is the fluid that surrounds the brain. CSF acts as a fluid buffer, protecting the brain from impact.
