What are body sends signals?

Your body sends signals to tell different parts what to do, just like a team of friends passing notes during a game.

How it works: Like a message in a bottle

Imagine your brain is the captain of a ship, and your body is the whole crew. When you want to move your arm, the captain writes a message on a piece of paper and throws it into the ocean, that's like a signal traveling through your nerves.

Your arm gets the message and says, "Okay, I'm going to move!" That’s how your body sends signals all over to help you walk, talk, laugh, or even eat an ice cream cone.

Signals are everywhere

Every time you blink, run, or feel a tickle on your nose, that's your body sending signals. It's like having tiny messengers inside you working together every second of the day! Your body sends signals to tell different parts what to do, just like a team of friends passing notes during a game.
