Large-diameter pain axons ____.

Question

Quizplus · Accepted Answer

Large-diameter pain axons carry sharp pain information, which is the initial sensation of pain felt as a sharp, pricking or stabbing sensation. In contrast, small-diameter pain fibers carry dull pain information, which is characterized as a persistent, burning, or aching sensation. Large-diameter fibers are also associated with larger cell bodies, while small-diameter fibers are associated with smaller cell bodies. Endorphins can modulate pain signaling, but they do not selectively affect large-diameter pain axons.
