B) sympathetic ganglia are within a few centimeters of the cNS parasympathetic ganglia are close to the visceral organs served. C) Sympathetic division has short preganglionic and long postganglionic fibers; parasympathetic has long preganglionic and short postganglionic fibers. D) Sympathetic has extensive branching of preganglionic fibers; parasympathetic has minimal branching of preganglionic fibers.
