context_page_description: Nociception is the sensory nervous system's process of encoding noxious stimuli. In nociception, intense chemical, mechanical, or thermal 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.
context_section_description: This overview discusses proprioception, thermoception, chemoception and nociception as they are all integrally connected.
