Cranial anatomy

Cranial anatomy refers to the structures of the skull that protect the brain. The skull is made up of several bones fused together, including the frontal, parietal, occipital, temporal, sphenoid, and ethmoid bones. These bones form a hard, protective case with openings called foramina for nerves and blood vessels. Inside, the brain sits within the cranial cavity, cushioned by cerebrospinal fluid. The skull also provides attachment points for muscles involved in chewing and facial expressions. Overall, the cranial anatomy is a complex and vital part of human structure that safeguards the brain and supports sensory functions.
