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.
Histology of the Dorsal Root Ganglion. Many of the cell bodies of the sensory and motor neurons of the peripheral neves are grouped into nodules or swellings called ganglia. There are two major types of ganglia in the peripheral nervous system: the craniospinal ganglia contain the cell bodies of sensory neurons of cranial and spinal nerves. The autnomic ganglia of the autonomic nervous system contain the cell bodies of the motor neurons of autonomic nerves.
