The main control center of the body, the brain is a complex and fragile organ composed of countless neurons arranged into numerous lobes and cortices.

The chief purpose of the skull is to protect the brain.
The main control center of the body, the brain is a complex and fragile organ composed of countless neurons arranged into numerous lobes and cortices. The hard, bony cranium surrounds the brain to shield it from damage. The skull also holds in the fluids that allow our brain to function. Those fluids serve a secondary purpose as well—they are the brain's "cushion," because we don't want our soft brains knocking against the inside of our hard heads!
An additional purpose of the skull is to give our face its shape. Human faces evolved to their current form for a reason. Our eyes need to be a certain distance apart to enable binocular vision; our ears need to be in specific places to allow binaural hearing; and our faces need anchors for dozens of muscles to allow us to make facial expressions.
