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. ==See also== * [[Postganglionic fibers]] ==External links== * [http://medic.med.uth.tmc.edu/Lecture/labeled/scheme.gif Diagram at tmc.edu] * [http://medweb.bham.ac.uk/research/toescu/Teaching/GIT/PSInnerv.htm Diagram at bham.ac.uk] * [http://www.arts.uwaterloo.ca/~bfleming/psych261/image29.gif Diagram at uwaterloo.ca] {{neuroscience-stub}} {{Autonomic}} [[es:Fibras preganglionares]] [[ps:پريګانګليونېک عصبي ريښې]]
