Now, in the same exact way that we discussed our pathway of the electrical signal, let's discuss the pathway in the parasympathetic case. So in the case of the sympathetic nervous system, our pre ganglionic neuron always begins in our spinal cord. But in this case, it can begin in a spinal cord or it also can begin in the brain. So the cell body begins in our brain or spinal cord. And now the axon is relatively long. So the axon is long compared to the axon of the post ganglionic cell.
