A neuron is like a tiny biological wire that runs around our body. Signals in our bodies are sent by electricity, and the little electric messages move up and down neurons. Then they tell the next neuron to wake up and start moving so that we can move our hands or blink.

A neuron is a tiny little little cell in your body, that helps you transmit information from your brain to somewhere else. Jessica is right in that they’re like tiny wires! But Neurons do lots of different jobs – some of them sense pain so you know if you’re stubbed your toe because of a neuron, some of them sense if something is hot. Some of them tell muscles to move around – like the ones in my fingers on this keyboard right now! At the spaces between neurons, one neuron releases lots of chemicals (called neurotransmitters – because they’re helping neurons transmit information) which tell the other neuron to pass on the message. Sometimes if you cut off neurons they can’t send information anymore – this can happen if you’re paralysed.
