What tells your hand to move when you touch something very hot?

Answer 1

Chactation:

Fire has a large amount of thermal energy, when it comes into contact with your relatively cold hand, it's thermal energy quickly flows into it. The nerves in that area absorb that energy, transform it into a weak electrical signal, so your neurons can understand the information. The information is processed by the neurons, and then they decide on a logical reaction -pulling away from the intense heat-. That's my guess to how it happens. This all happens in a fraction of a second.
