What would be the danger in lacking nociceptors? What will be an ideal response?
Nociceptors are responsible for sensing pain, so in their absence an individual’s ability to sense and
respond to pain would be greatly reduced. Directly, this could impact reflex actions in which rapid
response minimizes the damage done to the body. From a bigger perspective, the individual would be
less able to detect the pain caused by specific actions and thus may not learn to avoid them.
