So we still have our pre ganglionic cell that synapses with the post ganglionic cell. And in this case our neurotransmitter is also acetylcholine. Now we have a short post ganglionic axon. 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.
