Nociceptors are specialized nerve endings that respond to potentially damaging stimuli by sending signals to the spinal cord and brain, which are then interpreted as pain sensations. The gate-control theory of pain suggests that pain signals are regulated by a "gate" mechanism in the spinal cord, which can be opened or closed by various factors such as the release of endorphins or the focusing of attention away from the pain. This theory helps explain why some people are able to tolerate pain better than others, and why certain interventions such as relaxation or distraction techniques can be effective in reducing pain perception.
