Nociceptors are pain receptors that detect a wide range of stimuli and respond to: - ---CORRECT ANSWER--- Chemical, mechanical, and thermal stimulation The afferent system is: - ---CORRECT ANSWER--- Composed of nociceptors the dorsal horn of the spinal column (second-order neurons) and afferent neurons in the Aδ and C fibers (first-order neurons);spinothalamic tract (third-order neurons). Myelinated Aδ receptor transmission is - ---CORRECT ANSWER--- Fast and conveys mechanical and thermal localized pain. Unmyelinated polymodal C fiber transmission is: - ---CORRECT ANSWER--- Slower and conveys sharp, diffuse burning and aching sensations These primary-order neurons terminat
