What are neurotransmitters?

Neurotransmitters are tiny messengers that help your brain talk to other parts of your body.

Imagine you have a toy phone. When you call your friend, you speak into the phone, and they hear it on their end. That’s how neurotransmitters work, they send messages from one nerve cell to another, just like you sending a message through a phone.

When your brain wants to tell your hand to move, it sends out a signal. This signal is like a message that needs to cross the gap between two special cells called nerve cells. Neurotransmitters are like little helpers that jump across this gap to deliver the message on the other side.

Think of neurotransmitters as tiny notes you leave for your friend under their door. If you write, “Come play!” and slip it under their door, they’ll know what to do. Similarly, when a neurotransmitter lands on the next nerve cell, it tells that cell to send a signal somewhere else, like telling your muscles to move.

So, whether you're jumping, laughing, or even thinking, neurotransmitters are helping you do it all!
