Question

Quizplus · Accepted Answer

Fast pain is also known as acute pain and is caused by the stimulation of myelinated A-delta fibers. It is rapidly transmitted to the brain, resulting in a sharp and distinct pain sensation. It is generally well-localized and short-lived.

Answer: B
 Slow pain, also known as chronic pain, is caused by the stimulation of unmyelinated C fibers. It is poorly localized and has a longer duration than fast pain. Polymodal nociceptors are responsible for responding to a variety of damaging stimuli, including heat, cold, pressure, and chemicals.
