Final answer:
The adult human skull consists of 22 bones: 8 cranial bones and 14 facial bones. The cranial bones form the cranial cavity enclosing the brain, and except for the mandible, they are fused in adults. The number of points on the skull where thickness is measured depends on the method and purpose of the study.
Step-by-step explanation:
The skull is a bony structure that provides a framework for the head and protects the brain. In an adult human, the skull consists of 22 bones: 8 cranial bones and 14 facial bones. The cranial bones include the frontal bone, two parietal bones, two temporal bones, occipital bone, sphenoid bone, and the ethmoid bone. These cranial bones form the cranial cavity, which encloses the brain.
Apart from the mandible, which is moveable, the other bones in the adult skull are immobile and fused together. When determining the thickness of these bones, areas of measurement would typically be determined by the specific requirement of the study or medical analysis, such as a computed tomography (CT) scan. However, the question on how many points on the skull where thickness has been determined is not within the given information and depends on the context of the study or the method used for measuring bone thickness.
