In this case we had a long one. And now our synapse between the post ganglionic neuron and the fact the organ uses acetylcholine as a neurotransmitter, in this case we use epinephrine or norepinephrine. So this is a second difference between our sympathetic and parasympathetic nervous system. So the pre ganglionic neuron begins either in a spinal cord or in the brain. It then carries our electrical signal via a long axon to our synapse that uses acetylcholine. And then the signal is passed down to this one and at this location it uses our acetylcholine once again.
