Question

Quizplus · Accepted Answer

Capsaicin stimulates unmyelinated C fibers, which are responsible for transmitting pain and temperature sensations. These fibers can cause apnea and then rapid, shallow breathing when stimulated by capsaicin. Myelinated A fibers are responsible for transmitting touch and pressure sensations, while unmyelinated B fibers are involved in autonomic functions such as blood pressure regulation. Myelinated C fibers do not exist.
