How Does Sensory Neurons, Interneurons Work?

Your body has special messengers called sensory neurons and interneurons, which help you feel things and think about them.

Imagine you're playing with your favorite toy, maybe a rubber duck that squirts water. When the duck goes squish, it pushes against your finger, and that's when sensory neurons start working. They are like tiny helpers that send messages from your skin to your brain saying, “Hey, something touched me!”

Once the message reaches your brain, interneurons take over. Think of them as smart little translators who help different parts of your brain talk to each other. Maybe they tell your brain, “That was a fun squish!” or even “You should laugh now!”

So sensory neurons are like the first messengers who bring news from your body to your brain, and interneurons are like clever helpers who make sure that news gets understood and acted on, just like how you know to giggle when your rubber duck surprises you!
