Why are nociceptors so important?
Noriceptors are extremely important because they protect us from injury or even death. Noriceptors, or pain sensors, produce the perception of pain when they are traumatized. For example, if you start to drink a fluid that is very hot, you will likely spit it out, rather than swallow the fluid and risk being burned. The perception of burning is caused by direct trauma to nerve endings that relay this information to higher centers. As a result, you will act to avoid the painful stimulus. However, people with third-degree burns do not perceive pain, because the nerve endings supplying the burned area will have been destroyed.
