How many cranial bones are in an adult human skull?

Quick Answer

An adult human skull has 8 cranial bones. These bones form the cranium, which protects the brain.

The Full Story

The adult cranium is made of 8 bones: the frontal, two parietal, two temporal, occipital, sphenoid, and ethmoid bones. Together, these bones form a protective case around the brain. They meet at sutures, which are immovable joints in adulthood. The cranial bones are distinct from the facial bones, which shape the features of the face. In newborns and children, the skull bones are not fully fused, allowing growth of the brain and head.
