Question: does the parasympathetic nervous system has long preganglionic fibers?
Answer: The axons of presynaptic parasympathetic neurons are usually long. ... The pelvic splanchnic efferent preganglionic nerve cell bodies reside in the lateral gray horn of the spinal cord at the S2–S4 spinal levels. Their axons continue away from the CNS to synapse at an autonomic ganglion close to the organ of innervation.
