WebbHowever, it is limited in that the measurement of subjective thermal discomfort is an indirect measure of thermal behavior and does not, by definition, quantify thermal behavior . This is particularly important because quantifying thermal discomfort does not allow for insights regarding the level of thermal discomfort that ultimately motivates decisions to … WebbPeripheral AFFERENT NEURONS which are sensitive to injuries or pain, usually caused by extreme thermal exposures, mechanical forces, or other noxious stimuli. Their cell bodies reside in the DORSAL ROOT GANGLIA. Their peripheral terminals (NERVE ENDINGS) innervate target tissues and transduce noxious stimuli via axons to the CENTRAL …
