Question

Which of the following is true about pain receptors?

1) Alpha fibers respond to chronic pain.
2) Alpha fibers are associated with dull, aching pain.
3) Alpha fibers are associated with sharp, localized pain.
4) Beta fibers are associated with sharp, localized pain.

Answer 1

Alpha fibers are associated with sharp, localized pain.

Step-by-step explanation:

Pain receptors, also known as nociceptors, are responsible for sensing potentially damaging stimuli that are perceived as pain. Alpha fibers are associated with sharp, localized pain, while beta fibers are associated with dull, aching pain. Therefore, statement 3) 'Alpha fibers are associated with sharp, localized pain' is true about pain receptors.
