The cell bodies of the presynaptic neurons of both the parasympathetic and sympathetic systems are located within the central nervous system. These presynaptic autonomic neurons synapse only with postsynaptic autonomic neurons.he cell bodies of the presynaptic neurons of both the parasympathetic and sympathetic systems are located within the central nervous system. These presynaptic autonomic neurons synapse only with postsynaptic autonomic neurons.
For example, sympathetic nervous system increases the heart rate, whereas parasympathetic nervous system does the opposite. â¢ Postganglionic fibers of parasympathetic nervous system secrete acetylcholine, while that of sympathetic nervous system secrete adrenaline or noradrenaline at their synapse as neurotransmitters.â¢ Postganglionic sympathetic nerves are adrenergic, whereas postganglionic parasympathetic nerves are cholinergic.
