A) decreases;decreases
B) increases;increases
C) decreases;increases
D) increases;decreases
Gate-Control Theory
A theory proposing that the spinal cord contains a neurological "gate" that blocks or allows pain signals to proceed to the brain.
Spinal Cord Nerve Fibers
Bundles of axons within the spinal cord that transmit signals to and from the brain.
Increases Pain
The worsening or intensification of pain sensations in the body.
- Explain the biological foundations underlying the sensation of pain and the elements that affect the experiences of pain.
- Acquire knowledge on the physiological and psychological dimensions of pain management and regulation.

Final Answer :
D
Explanation :
According to the gate-control theory, activation of smaller spinal cord nerve fibers increases pain because these fibers transmit pain signals. Activation of larger spinal cord nerve fibers decreases pain because these fibers can inhibit the transmission of pain signals, effectively "closing the gate" to pain.
