The soma of nociceptors are generally compact in diameter in both the dorsal pathway and in other sensory ganglia. Neurons with modest soma diameter generally have myelinated Aδ fibers or unmyelinated C fibers, while Aα/β-fibers can be found on cells of larger Proportions. Soma diameter and axon myelination are usually not related to nociceptor performance [four]. In reality, the soma of non-visceral nociceptors are scaled-down than Those people of visceral nociceptors, but this variation in sizing has no bearing on their own respective levels of perform [four].

In some of these sufferers hyperactivity of the sympathetic nervous procedure Evidently performs A significant job in sustaining the pain because selective blockade with the sympathetic outflow produces fast and remarkable aid. The pain is usually accompanied by indications of sympathetic hyperactivity, such as a cold (vasoconstricted), sweaty limb.
