The soma of nociceptors are generally smaller in diameter in both the dorsal pathway As well as in other sensory ganglia. Neurons with modest soma diameter normally have myelinated Aδ fibers or unmyelinated C fibers, whilst Aα/β-fibers are available on cells of greater dimensions. Soma diameter and axon myelination are usually not affiliated with nociceptor features [four]. In actual fact, the soma of non-visceral nociceptors are lesser than People of visceral nociceptors, but this change in size has no bearing on their own respective degrees of functionality [4].

Their specializations allow the receptors to innervate various central and peripheral targets. This differentiation occurs in the two perinatal and postnatal periods. The nonpeptidergic nociceptors switch from the TrkA and start expressing RET proto-oncogene, which can be a transmembrane signaling component that permits the expression of glial mobile line-derived neurotrophic element (GDNF).
