In the [[autonomic nervous system]], fibers from the [[central nervous system|CNS]] to the [[autonomic ganglion|ganglion]] are known as '''preganglionic fibers'''.
All preganglionic fibers, whether they are in the [[sympathetic nervous system|sympathetic division]] or in the [[parasympathetic nervous system|parasympathetic division]], are [[cholinergic]] (that is, these fibers use [[acetylcholine]] as their [[neurotransmitter]]).
Sympathetic preganglionic fibers tend to be shorter than parasympathetic preganglionic fibers because sympathetic ganglia are often closer to the spinal cord than are the parasympathetic ganglia.
