The skull is a bony structure that forms the head of the skeleton in most vertebrates. It consists of the cranium, which encloses and protects the brain, and the mandible, or jawbone. The skull also houses the eye sockets, nasal cavity, and ear structures. The shape and size of the skull can vary among different species.
It would normally be seen as a dome-shaped roof of an octagonal room.
