Web(A)Parasympathetic fibers have a craniosacral outflow. (B) The two divisions of the somatic nervous system are sympathetic and parasympathetic. (C) The sympathetic division has short preganglionic fibers and long postganglionic fibers. (D) Most parasympathetic ganglia are located in or near the visceral effector organ. WebA postganglionic fiber —the axon from a ganglionic neuron that projects to the target effector—represents the output of a ganglion that directly influences the organ. Compared with the preganglionic fibers, postganglionic sympathetic fibers are long because of the relatively greater distance from the ganglion to the target effector.

In the autonomic nervous system, fibers from the CNS to the ganglion are known as preganglionic fibers. All preganglionic fibers, whether they are in the sympathetic division or in the parasympathetic division, are cholinergic (that is, these fibers use acetylcholine as their neurotransmitter) and they are myelinated. Sympathetic preganglionic fibers tend to be shorter than parasympathetic preg… WebThe sympathetic division of the ANS has highly branched POST-GANGLIONIC FIBERS. Why?
