Group C nerve fibers are one of three classes of nerve fiber in the central nervous system (CNS) and peripheral nervous system (PNS). The C group fibers are unmyelinated and have a small diameter and low conduction velocity, whereas Groups A and B are myelinated. Group C fibers include postganglionic fibers in the autonomic nervous system (ANS), and nerve fibers at the dorsal roots (IV fiber). … WebbConsists of 2 divisions: Somatic Nervous System and Automatic Nervous System.

WebbAfferent fibers, arising from the trigeminal nerve and the upper cervical spinal cord segments, innervate the proximal parts of the large cerebral vessels and dura mater. These sensory fibers terminate within the lower brainstem and upper cervical cord. Nociceptive information is then relayed to the thalamus and cortical pain areas.

WebbA-delta fibers are small-diameter (1 to 6 μm), myelinated primary afferent fibers; C fibers are smaller-diameter (1.0 μm) unmyelinated primary afferents.
