Parasympathetic Nervous System An Overview Sciencedirect Topics

Sympathetic preganglionic fibers tend to be shorter than parasympathetic preganglionic fibers because sympathetic ganglia are often closer to the spinal cord while parasympathetic preganglionic fibers tend to project to and synapse with the postganglionic fiber close to the target organ.

All preganglionic fibers whether they are in the sympathetic nervous system SNS or in the parasympathetic nervous system PSNS are cholinergicthat is these fibers use acetylcholine as their neurotransmitterand are myelinated. Figure 154 Connections of Parasympathetic Division of the Autonomic Nervous System Neurons from brain-stem nuclei or from the lateral horn of the sacral spinal cord project to terminal ganglia near or within the various organs of the body.

The parasympathetic division of the autonomic nervous system utilizes norepinephrine as a postganglionic neurotransmitter has a relatively short preganglionic neuron utilizes acetylcholine as a postganglionic neurotransmitter includes the adrenal medulla none of these are correct 10. Utilizes acetylchoine as a preganglionic neurotransmitter. Splanchnic nerves are mixed motor and sensory nerves. Because parasympathetic fibers never run in spinal nerves rami communicantes are associated only with the sympathetic division.
