Answer 1

Answer:

B. 8

In adults, the 8 cranial bones are:

1. Frontal bone

2. Parietal bone (2)

3. Occipital bone

4. Temporal bone (2)

5. Sphenoid bone

6. Ethmoid bone

However, in infants, the cranial bones are not yet fused, resulting in 22 separate bones. As the infant grows and develops, these bones gradually fuse together to form the 8 adult cranial bones.
