Which anatomical description is true of the parasympathetic division of the autonomic nervous system?

The parasympathetic nervous system exits the central nervous system at cranial nerves III, VII, IX and  X and the sacral spinal roots. Nerve fibers from the central nervous system to the ganglion are preganglionic fibers and use acetylcholine as a neurotransmitter. The parasympathetic nervous system innervates visceral organs and glands. The parasympathetic nervous system slows the heart rate, stimulates digestion and relaxes sphincters.
