This neuron has its cell body during the dorsal root ganglion and a protracted procedure, the axon, that divides and sends a single department out on the periphery and a person in to the spinal wire (Figure seven-2). The axons of Key afferent nociceptors are rather skinny and perform impulses slowly but surely.
