- | |||
- | The skull is a bone structure that forms the head in vertebrates. It supports the structures of the face and provides a protective cavity for the brain.The skull is composed of two parts: the cranium and the mandible.In humans, these two parts are the neurocranium and the viscerocranium (facial skeleton) that includes the mandible as its largest bone. The skull forms the anterior-most portion of the skeleton and is a product of cephalisation—housing the brain, and several sensory structures such as the eyes, ears, nose, and mouth.[3] In humans these sensory structures are part of the facial skeleton. | ||

- | The skull is made up of a number of fused flat bones, and contains many foramina, fossae, processes, and several cavities or sinuses. In zoology there are openings in the skull called fenestrae. | ||
