Which statement accurately describes the gate-control theory of pain?

Question

Quizplus · Accepted Answer

The gate-control theory of pain proposes that a "gate" in the spinal cord can either open or close to allow or block pain signals from reaching the brain. This gate is regulated by the activity of small and large nerve fibers that compete to transmit their signals to the brain. When large fibers are active (e.g., due to touch or other non-painful input), they can close the gate and prevent pain signals from being transmitted. On the other hand, when small fibers are active (e.g., due to tissue damage or inflammation), they can open the gate and allow pain signals to be transmitted to the brain. Therefore, the gate-control theory suggests that pain perception is not solely determined by the nature or intensity of the noxious stimulus, but can also be modulated by other sensory input and by the activity of the nervous system.
