Explain why adaptation of pain receptors would not be desirable and yet the adaptation of other
sensory systems is beneficial.
What will be an ideal response?
The purpose of pain is to reduce damage of the body. In adaptation, a constant stimulus results in
fewer action potentials being sent to the central nervous system. This allows the brain to focus on
changes in the environment while ignoring stimuli that remain constant. With pain, however,
adaptation could lead to a continuation in or an increase of damage. For this reason, pain receptors do
not adapt or reduce the frequency of action potentials.
