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 … See more Location C fibers are one class of nerve fiber found in the nerves of the somatic sensory system. They are afferent fibers, conveying input signals from the periphery to the central nervous system. See more C fibers synapse to second-order projection neurons in the spinal cord at the upper laminae of the dorsal horn in the substantia gelatinosa. The second-order projection neurons … See more Activation of nociceptors is not necessary to cause the sensation of pain. Damage or injury to nerve fibers that normally respond to innocuous stimuli like light touch may lower their activation threshold needed to respond; this change causes the organism to feel intense pain … See more Because of their higher conduction velocity owing to strong myelination and different activation conditions, Aδ fibers are broadly responsible for the sensation of a quick shallow … See more Microneurography is a technique using metal electrodes to observe neural traffic of both myelinated and unmyelinated axons in See more • A nerve fibers • B nerve fibers • Free nerve ending See more Weband efferent fibres.
