If you touch something that is very hot, your hand moves away quickly before you even feel the pain. You don't have to think about it because the response is a reflex that does not involve the brain. A reflex is a rapid, unlearned, involuntary (automatic) response to a stimulus (change in the environment).

The nervous system will get information through our senses.
So... If you touch a hot surface you pull back your hand because your nervous system will react and give you caution.
I hope it helps you!
