The function of the cranial cavity is to provide protection and support for the brain. It houses and encloses the brain, protecting it from external forces and reducing the risk of injury. The cranial cavity is surrounded by the bones of the skull, which provide a strong and rigid structure to safeguard the delicate brain tissue. Additionally, the cranial cavity contains cerebrospinal fluid (CSF) that acts as a cushion and shock absorber, further protecting the brain from impact or sudden movements. The cranial cavity also serves as a space for blood vessels, nerves, and other structures connected to the brain to pass through.
