The skull is the shield that protects the delicate brain and the main sense organs, such as the eyes. It is made of a combination of bones that fit together tightly like the pieces of a jigsaw.
The top of the skull works like a crash helmet, encasing the brain. The lower part is a supportive structure, shaping the face and anchoring the muscles that create facial expressions. The bones of the skull are strong, but also light so that humans can hold their heads up easily.
Bone count
There are 22 bones in the human skull. Eight form the cranium surrounding the brain, while 14 bones make up the face.
Strong case
All but one of the skull bones are locked in place by joints called sutures. The only moving bone is the mandible in the lower jaw, which has a hinged joint for breathing, eating, drinking, and speaking.
