1. 10

2. 8

3. 14

4. 12

The correct answer is: 8

The human skull is composed of a total of eight cranial bones. These bones include the frontal, parietal, temporal, occipital, sphenoid, and ethmoid bones. They are vital to the structure and protection of the brain, forming the protective case around it. Understanding the number and types of cranial bones is essential in many fields, including esthetics, as facial treatment methods may rely on a foundational understanding of skeletal structure. The cranial bones are distinct in their functions and contributions to the overall anatomy of the skull, distinguishing the human skull from that of other species.
