Group C nerve fiber - Wikipedia
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), a… See more

- C fibers are unmyelinated unlike most other fibers in the nervous system. [ 1] This lack of myelination is the cause of their slow conduction velocity, which is on the order of no more than 2 m/s. [ 1]Learn more:C fibers are unmyelinated unlike most other fibers in the nervous system. [ 1] This lack of myelination is the cause of their slow conduction velocity, which is on the order of no more than 2 m/s. [ 1]en.wikipedia.org/wiki/Group_C_nerve_fiberC-type fibers are unmyelinated fibers that form one of these groups, and they are involved in the afferent transfer of temperature, burning pain, and itch from the periphery to synapse, principally in lamina I and II of the dorsal spinal horn.pubmed.ncbi.nlm.nih.gov/32119348/C tactile afferents are nerve receptors in mammalian skin that generally respond to nonpainful stimulation such as light touch. For this reason they are classified as ‘low-threshold mechanoreceptors’. As group C nerve fibers, they are unmyelinated and have slow conduction velocities.en.wikipedia.org/wiki/C_tactile_afferent
