In anatomy, a ganglion (/ËÉ¡Ã¦ÅÉ¡liÉn/ GANG-glee-Én; plural ganglia) is a nerve cell cluster or a group of nerve cell bodies located in the autonomic nervous system and sensory system. Ganglia house the cell bodies of afferent nerves.
In vertebrates, there are two major groups of ganglia: the dorsal root ganglia and the autonomic ganglia. The ganglia located near and associated with the spinal nerves are the dorsal root ganglia. The cell bodies of sensory neurons are found in these ganglia. The other group is called autonomic ganglia.
