The Brain [brān]
An organ of soft nerve tissue contained in the skull of vertebrates.

Inside your skull your brain controls everything you do. This collection of billions of neurons is more powerful and faster than any computer, and it's always working. It guides activities we actively control, such as reading, talking, jumping, and eating as well as many, such as breathing, blinking, and pumping blood, that we don't.
