Imagine the electricity in your house. It works because cables carry energy from the power station to your lights, TV, and fridge.

Your body works in a similar way!
The nerves are like those cables, and your brain is the power station.

Even though you cannot see them, nerves run all through your body. They carry tiny electrical signals that help you:
Feel things
Move your muscles
Breathe, sweat, and digest food

Nerves help your brain talk to your body, and your body talk back.
