The autonomic ganglia and plexuses are a collection of ganglia where autonomic preganglionic neurons arising from the CNS synapse with postganglionic neurons outside the CNS, i.e. in the peripheral nervous system. Many of the ganglia contain nerves of the sympathetic and parasympathetic nervous systems. Postganglionic neurons distribute to many visceral and vascular end organs.
They can be divided by body region:
-
craniofacial
-
cervical
-
thoracic
-
abdominopelvic
-
coccygeal
