How many cranial bones are there?

1. 6

2. 8

3. 10

4. 12

The correct answer is: 8

The human skull is comprised of eight cranial bones that form the protective casing for the brain. These bones are essential for providing structure and support, as well as protecting the underlying brain tissue from trauma. The eight cranial bones include the frontal, parietal (two), temporal (two), occipital, sphenoid, and ethmoid bones. Each of these bones plays a critical role in the overall architecture of the skull and in the protection of the brain, as well as serving attachment points for the meninges and supporting various facial structures. Understanding the anatomy of the cranial bones is fundamental for radiography, particularly in imaging the skull and diagnosing conditions that might affect cranial structure or trauma.
