What are receptor neurons?

Receptor neurons are like special messengers that tell your brain when something happens on your body.

Imagine you're playing outside and you touch a hot stove, ouch! That's because receptor neurons in your skin sense the heat and send a message to your brain, telling it, "Hey, this is hot!" Then your brain says, "Move your hand!"

Think of receptor neurons like feeler sensors on your skin. They're tiny but very smart, they can tell if something is cold, warm, rough, smooth, or even painful.

When you touch something, the receptor neurons get a little "nudge" from that thing. This nudge makes them send a signal through wires (called nerves) all the way to your brain. Your brain then figures out what happened, like if it was hot, cold, or maybe even ticklish!

So next time you feel something on your skin, remember: receptor neurons are working hard to let your brain know what's going on!
