What are ruffini endings?

Ruffini endings are tiny sensors in your skin that help you feel when something is warm or cold.

Imagine you're playing outside on a chilly day. You touch a metal slide, whoosh, it feels super cold! That’s because the Ruffini endings inside your fingers are sending messages to your brain, telling it, “Hey, this is cold!”

Now think of those same Ruffini endings as little detectives who love to investigate changes in temperature. They’re like the ones who stand near a door and whisper, “It’s getting warmer in here!” or “The room just got colder!”

These sensors are especially good at noticing slow changes, like when you sit on a bench that starts feeling warm after being out in the sun for a while.

Ruffini endings are made of special nerve cells deep inside your skin. When the temperature around them changes, whether it gets warmer or colder, these little sensors send signals up to your brain, helping you understand what’s happening with the things you touch.
