What part of the skull is involved in the structure supporting the brain?

The cranium is the part of the skull that serves as the protective structure for the brain. It is composed of several bones that are fused together to create a solid enclosure, safeguarding the delicate tissues of the brain from injury. The cranium also forms the upper portion of the skull, which houses and protects the brain while providing attachment points for the muscles that enable head movement.

The frontal bone contributes to the formation of the forehead and the eye sockets, while the temporal bones are located at the sides of the skull, playing a role in housing structures such as the ears. The zygomatic bone, or cheekbone, primarily supports the structures of the face rather than aiding in brain protection. While all options listed are important parts of the skull, it is the cranium that specifically and exclusively provides the protective structure supporting the brain.
