Quizplus · Accepted Answer

Parasympathetic preganglionic fibers are typically long and postganglionic fibers are short. This is because preganglionic fibers typically originate in the brainstem or sacral region of the spinal cord and travel a longer distance to reach their target ganglia, where they synapse with postganglionic fibers that are much shorter and extend to their target organs.
