What is the primary function of the cranium?

The cranium serves the vital function of protecting the brain. It is made up of several bones that are fused together to create a strong, encasing structure that shields the brain from physical damage, such as impacts and injuries. The brain is a delicate organ that regulates essential bodily functions, so the protective role of the cranium is critical for overall health and survival. Furthermore, the cranial bones also support and contribute to the structure of the face and skull, but their primary purpose is indeed to safeguard the brain from external forces.
