Document Summary
Thermoreceptors: sensory receptors that signal information about changes in skin temperature, two distinct populations of thermoreceptors, warmth fibers, cold fibers. *notably, the 2 population overlaps at 37 degrees celcius. (our body temperature) This is because the 2 system is designed to detect variability from our body temperature: body is constantly regulating internal temperature (purpose, thermoreceptors respond when you make contact with an object warmer or colder than your skin. *also the type of receptors associated with temperature is also associated with the receptors for pain. *thermoalgesia = term that refers to both pain and temperature receptors. *ther(cid:373)ore(cid:272)eptors do(cid:374)"t ha(cid:448)e a(cid:374)(cid:455) (cid:374)er(cid:448)e e(cid:374)di(cid:374)g*** (cid:894)aka free-nerve endings) Pain perception: is pain a separate system or is it the same (meaning it"s a (cid:373)atter of i(cid:374)te(cid:374)sit(cid:455)(cid:895). Intensity theory responds to both innocuous and noxious stimuli: nociceptors. *in the 1950s, there was a discovery that confirmed the specificity theory. Nociceptors means the fibers specifically responds to pain (and not to stimuli of low intensity)
