Wut Is Skull?

Human Skulls

In human the adult skull is normally made up from 22 bones. Except for mandible, all of the bones of the skull are joins together by sutures, rigid articulations permitting very little movement. Eight bones from the neurocranism (braincase)- including the frontal, parietals, occipital bones, sphenoid, temporals and ethmoids- a protective vault surrounding the brain. Fourteen bones from the splanchnocranium, the bones supporting the face. Enchased within the temporal bones are the six ear ossicels of the middle ears, though this are not part of the skull. The hyoid bone, supporting the tongue, is usually not considered as a part of the skull either, as it does not articulate with any bones. The skull is the protector of the brain.
