Which feature reflects sensitized peripheral nociceptors?

Explanation:
Nociceptor sensitization after tissue injury lowers the threshold for activation and increases the responsiveness of peripheral pain receptors, leading to heightened pain signals in response to stimuli that might not be painful before. The statement that describes sensitized peripheral nociceptors directly captures this change in the periphery, making it the best choice. Central inhibition of nociception would dampen pain signaling, not reflect peripheral sensitization. Decreased nociceptor sensitivity would do the opposite, reducing pain perception. Muscle hypertrophy is unrelated to how nociceptors become sensitized.
