The soma of nociceptors are commonly smaller in diameter in both the dorsal pathway and in other sensory ganglia. Neurons with tiny soma diameter normally have myelinated Aδ fibers or unmyelinated C fibers, even though Aα/β-fibers are available on cells of much larger dimensions. Soma diameter and axon myelination will not be connected to nociceptor functionality [four]. In reality, the soma of non-visceral nociceptors are smaller than those of visceral nociceptors, but this distinction in sizing has no bearing on their own respective levels of functionality [4].
