Is the cranium solid at birth?

Answer 1

The cranium is not solid in a sense that the bones are fusing together. There are eight crainal bones that surround and protect the brain. The bones fuse together at joints known as sutures. When the sutures are completely fused together the skull is solid

Answer 2

No, the cranium of a newborn baby is not solid. It is made up of several bones that are not fully fused together. This allows for some flexibility and movement to accommodate the rapid growth of the brain in early infancy.
