An interesting instance is always that of corneal nociceptors, which might be activated by weaker stimuli than pores and skin nociceptors are what are pain receptors [five]. The character of your stimulus is likewise crucial. Stimuli brought about by reducing or crushing, by way of example, activate most skin nociceptors but usually do not activate Those people within the joints, muscles, or viscera, which as a substitute quickly reply to other kinds of mechanical forces, like rotation and distention [5].
