Autonomous ganglion

Autonomous ganglia ( singular : autonomous ganglion , Latin ganglia autonomica or ganglion autonomicum ), also called vegetative autonomic ganglia , are collections (clusters) of multipolar nerve cell bodies ( perikaryen ) in the peripheral nervous system from which nerve fibers originate. Depending on the type of fiber, a distinction is made between the sympathetic ganglion ( ganglion sympathicum ) and the parasympathetic ganglion ( ganglion parasympathicum ). The multipolar nerve cells vary in size and are surrounded by mantle cells .

Autonomous ganglia act as switching points for nerve fibers in the autonomic nervous system . The preganglionic nerve fibers ( Neurofibrae preganglionicae ) open into the autonomic ganglion . The emerging switched nerve fibers are the postganglionic nerve fibers ( Neurofibrae postganglionicae ). The autonomic ganglia are part of the sympathetic chain ( sympathetic trunk ) or are prävertebral , that is, before the spine . Autonomous ganglia also refer to clusters of nerve cells on the walls of the internal organs and clusters of nerve cells in the course of vegetative nerves.
