What are the bones of the brain case?

The brain case, or cranial cavity, is primarily formed by eight bones: the frontal bone, parietal bones (two), temporal bones (two), occipital bone, sphenoid bone, and ethmoid bone. These bones are fused together to protect the brain and support its structure. The frontal bone forms the forehead, parietal bones create the upper sides, temporal bones house the ears, the occipital bone forms the back and base, while the sphenoid and ethmoid bones contribute to the base and the nasal cavity, respectively. Together, they provide both protection and support for the brain.
