Receptors!

There are two main types of receptors influencing our musculoskeletal system: mechanoreceptors and nociceptors.

Both send signals to the brain — but you can often tell which one is active by noticing what makes it feel better.

This is what we call an anti-stimulus:

• If rubbing the area helps → you’re likely downregulating mechanoreceptors.
• If deep pressure brings relief → you’re probably dampening nociceptors.

So next time you catch yourself digging your thumb into a sore muscle, remember:
your body is most likely trying to turn down the signal from a nociceptor.

Nociceptors carry noxious stimuli so think pain receptors.
Mechanoreceptors are stretch, pressure and vibration receptors so most muscle movements.

Your instincts are usually correct when it comes to downregulating receptors!
