Autonomic ganglion

Autonomous ganglia (singular: autonomic ganglion, lat Autonomica Ganglia and ganglion autonomicum ), also called vegetative autonomic ganglia, are accumulations (clusters) of multipolar nerve cell bodies ( perikarya ) in the peripheral nervous system which give rise to nerve fibers. Depending on the type of fiber, a distinction ( ganglion sympathicum ) and the parasympathetic ganglion ( ganglion parasympathicum ) between the sympathetic ganglion. The multipolar neurons have a different size and are surrounded by sheath cells.

Autonomous ganglia serve as switch points of nerve fibers of the autonomic nervous system. In the autonomic ganglion, the preganglionic nerve fibers terminate ( Neurofibrae preganglionicae ) a. The exiting switched nerve fibers are the postganglionic nerve fibers ( Neurofibrae postganglionicae ). The autonomic ganglia are part of the sympathetic trunk ( sympathetic trunk ) or are prävertebral, ie front of the spine. As autonomic ganglia also clusters of nerve cells on the walls of the internal organs and clusters of nerve cells in the course called vegetative nervous.
