Which nociceptor fibers are characterized by having unmyelinated axons, resulting in slower conduction speed?

Answer

C-fibers

C-fibers possess unmyelinated axons, which causes them to conduct signals slower than A-fibers, and they are responsible for mediating the slower, burning quality of pain. They constitute approximately 70% of all nociceptors.
