The Human skull plays a vital role in protecting the brain. It is comprised of 22 bones (not including the ossicles in the ears). The bones in the human skull are all attached to each other by sutures, fibrous joints which makes the bones immovable. The one exception to this is the mandible which is mobile and not attached by sutures. All of the bones which are joined by sutures form the cranium .
