What are nerve signals?

Nerve signals are like messages that help your body talk to itself.

Imagine you're playing with a toy telephone. When you speak into it, the message travels through the wire and comes out of the other phone. That's how nerve signals work, they send messages from one part of your body to another.

Your body is full of nerves, which are like tiny wires that carry these messages. When you touch something hot, a message goes up your arm through these nerves and tells your brain, “Oh no, it’s hot!”

Then your brain sends back a message, telling your hand to move away, just like when you hang up the phone after talking.

These messages are made of electricity. Your body uses tiny sparks of electricity to send these signals quickly through your nerves. It's like lighting up a flashlight in a dark room, fast and clear!

So, next time you feel something or move your hand, remember: it’s all thanks to nerve signals working like a phone line for your body!
