What does a skull do?

Answer:
A skull acts as armor to protect the brain. While the skull is capable of fractures and breakage, it protects the brain floating in Cerebrospinal fluid. However, because the brain is floating in this fluid the skull can also act as a damaging wall as the brain slaps back and forth during head banging, car crashes, severe shaking and any other sort of sudden go and stop motion that effects the head.

It protects the brain.
