The soma of nociceptors are commonly modest in diameter in equally the dorsal pathway and in other sensory ganglia. Neurons with tiny soma diameter normally have myelinated Aδ fibers or unmyelinated C fibers, when Aα/β-fibers are available on cells of larger Proportions. Soma diameter and axon myelination are not connected to nociceptor functionality [4]. The truth is, the soma of non-visceral nociceptors are lesser than These of visceral nociceptors, but this variance in measurement has no bearing on their respective levels of functionality [four].
