A housewife was preparing hot meal for her family.
She accidentally placed her fingertip into some boiling
soup, but quickly withdrew it. She felt significant
pain in the finger immediately after that. Which of the
following is the most likely explanation for this time lag?

B The pain receptors present on her finger skin are
less efficient, so information regarding pain is
