Tap your skull and feel how hard it is. That's because it's made up of bones fused (joined) together and has the very important job of protecting your brain.
Your skull also supports your face and mouth muscles.
When you are a baby your skull is very soft, and gets harder in the first few months of your life. The skull at the front of your head – that covers and protects your brain – is called the cranium. You also have fourteen bones at the front part of your skull that shape your whole face (including your nose bones and jaw).
The shape of our skull will decide what a person will look like. That's why experts can use a skull of a dead person to help them find out what that person might have looked like when they were alive.
