How does menthol act on nociceptors?
a) Menthol blocks the transmission of pain signals by inhibiting neurotransmitter release from nociceptors.
b) Menthol stimulates nociceptors and increases their sensitivity to pain stimuli.
c) Menthol desensitizes nociceptors by activating TRPM8 receptors, leading to a decrease in their responsiveness to pain stimuli.
d) Menthol activates endogenous pain modulation pathways, leading to the inhibition of nociceptor activity.
