Question

The gate-control theory of pain suggests that ________.
A) the pain signals must pass through a kind of "gate" located in the spinal cord 
B) the skin receptors act as a gate for the pain sensation
C) the cortex blocks pain unless released by substance P
D) the gate is a physical structure that blocks pain signals

Quizplus · Accepted Answer

The gate-control theory proposes that there is a "gate" located in the spinal cord that can either allow or block pain signals from being transmitted to the brain. This "gate" is modulated by sensory, emotional, and cognitive factors, and can be influenced by factors such as distraction, relaxation, and even placebos. Option B is incorrect because skin receptors are not the gate itself, but they do play a role in transmitting signals to the gate. Option C is incorrect because although substance P is involved in transmitting pain signals, it is not involved in the gating mechanism proposed by the theory. Option D is incorrect because the gate is not a physical structure, but rather a hypothetical mechanism proposed by the theory.
