cranial cavity
The cranial cavity is a crucial component of the human skull, providing protection and support for the brain. It is a hollow space within the skull that houses and encases the brain, one of the most vital organs of the central nervous system. The cranial cavity is formed by the eight cranial bones, which include the frontal, parietal, temporal, occipital, sphenoid, and ethmoid bones. Its main function is to safeguard the delicate brain from external forces, such as impacts and injuries. The cerebrospinal fluid (CSF) surrounds and cushions the brain, acting as a shock absorber that further protects it from sudden movements or jolts. The cranial cavity also plays a crucial role in maintaining the brain's internal environment. It regulates the temperature and pressure around the brain, creating a stable and optimal environment for its proper functioning. Furthermore, the cranial cavity is essential for supporting the attachments of various structures, such as blood vessels
