nociception

Nociception is the sensory nervous system’s response to certain harmful or potentially harmful stimuli.

Nociception (also nocioception, from Latin nocere ‘to harm or hurt’) is the sensory nervous system’s process of encoding noxious stimuli. In nociception, intense chemical (e.g., cayenne powder), mechanical (e.g., cutting, crushing), or thermal (heat and cold) stimulation of sensory nerve cells called nociceptors produces a signal that travels along a chain of nerve fibers via the spinal cord to the brain. Nociception triggers a variety of physiological and behavioral responses and usually results in a subjective experience, or perception, of pain in sentient beings.
