OLogy: Draw Your Nervous System

Explore your nerves by creating a life-sized drawing.

Whenever you see, hear, and feel — and whenever you think, move, and even breathe — your brain buzzes with the activity of neurons.

Neurons are tiny cells that are the building blocks of the nervous system . They come in many shapes and sizes. Some stretch from the spinal cord all the way to the toes and can be more than 3 feet (1 meter) long!

Neurons send messages from different parts of your body to your brain , all around your brain, and from your brain out to the muscles in your body.

They can send more than 100 signals a second, at speeds up to 400 kilometers (250 miles) an hour. That’s four times faster than a moving car on the highway!
