C Fiber Stimulation
... The two types of C fibers are Dorsal root and Sympathetic. 1. Dorsal root fibers serve the modality of pain, warm and cold temperature, and touch. 2. The sympathetic type involves postganglionic sympathetic fibers. The pain produced by C fibers is characterizized as dull, often poorly localized and ...
