The brain is essential. Without it, you couldn’t live.

As it is very fragile, it must be well protected, inside your skull.

It’s connected to the rest of your body by your nerves. They’re like long wires that carry information.

Your brain receives and analyses the information coming from your organs, like your eyes, your skin, your nose, your ears…

Then it makes decisions and orders your body to make movements. It’s the boss!
