Which type of fibers are considered small and unmyelinated?

• A. A fibers
• B. B fibers
• C. C fibers
• D. D fibers

Answer: (C)

C fibers are small and unmyelinated, making them distinct from other nerve fibers. These characteristics significantly influence their function within the nervous system. Due to their small diameter and lack of myelin sheath, C fibers conduct nerve impulses more slowly compared to myelinated fibers, such as A and B fibers. This slow conduction is crucial for their primary role, which includes transmitting pain signals, particularly those associated with dull or aching sensations, as well as some autonomic functions. C fibers also play an essential role in the body's response to injury and the perception of pain. Their unmyelinated nature means that they are often more involved in chronic pain pathways and can contribute to sensations of discomfort that persist over time. Understanding the properties of C fibers is important in chiropractic care and pain management, allowing practitioners to address the mechanisms of pain comprehensively.
