In vertebrates, including humans,pain can be split into two distinct processes.In first, nerves and the skin sense something harmful and communicate that information to the spinal cord.There, motor neurons activate movements that make us rapidly jerk away from the threat.This is the physical recognition of harm
called nociception,and nearly all animals,even those with very simple nervous systems,experience it.Without this ability, animals would be unable to avoid harm
and their survival would be threatened.
