Feeling pain

What's this?Play health video with audio description: //


Ouch!!! Gotcha!

Pain, although often uncomfortable, is a protective mechanism that alerts us to potential or actual harm to the body's tissues.

Here, the peripheral nervous system sent a pain message to the brain that a bee sting occurred on the nose.

Let's take a look at an instant replay to see how this communication works.

The pain receptors in the skin detect tissue damage from the bee sting. Then, the peripheral nerves send a pain signal to the brain. The brain analyzes the pain signal.


In turn, the brain delivers a message back to the muscles of the arm to react.

Hasta la beesta, babee!

As you can tell, it's a very effective system.
