The soma of nociceptors are generally little in diameter in both the dorsal pathway As well as in other sensory ganglia. Neurons with tiny soma diameter usually have myelinated Aδ fibers or unmyelinated C fibers, even though Aα/β-fibers can be found on cells of larger dimensions. Soma diameter and axon myelination aren't linked to nociceptor functionality [four]. In fact, the soma of non-visceral nociceptors are lesser than those of visceral nociceptors, but this variance in dimension has no bearing on their respective degrees of operate [4].
