C Fibers

C fibers are a type of nerve fiber in the nervous system responsible for transmitting slow, dull, and aching pain signals. They are unmyelinated, meaning they lack a myelin sheath, which results in slower signal transmission compared to other fibers. C fibers also carry sensations like temperature (particularly warmth) and certain types of touch. They play a crucial role in alerting the brain to ongoing or persistent pain, helping the body respond to injury or discomfort over time. Their activity is essential for detecting and regulating long-lasting pain sensations, contributing to the overall pain experience.
