What is "cranium"?

The cranium is a singular body part that encompasses the skull, protecting the brain and supporting various sensory organs. It consists of several fused bones, including the frontal, parietal, temporal, occipital, sphenoid, and ethmoid bones. The cranium provides vital structural integrity to the head and face, safeguarding the delicate brain from external impacts. It also houses and supports the eyes, ears, and nasal cavity. The cranium's unique shape and composition allow for the complex functions of the brain, such as cognition, sensory perception, and motor control.
