parasympathetic ganglion

The ciliary ganglion is a parasympathetic ganglion located in the posterior orbit.

Parasympathetic ganglia are the autonomic ganglia of the parasympathetic nervous system.

The otic ganglion is a small, oval shaped, flattened parasympathetic ganglion of a reddish-gray color, located immediately below the foramen ovale in the infratemporal fossa.

They are essentially of two types: chromaffin or sympathetic paraganglia made of chromaffin cells and nonchromaffin or parasympathetic ganglia made of glomus cells.

The pterygopalatine ganglion (meckel's ganglion, nasal ganglion or sphenopalatine ganglion) is a parasympathetic ganglion found in the pterygopalatine fossa.

Tiny parasympathetic ganglia are scattered around forming the submucosal plexus (or "Meissner's plexus") where preganglionic parasympathetic neurons synapse with postganglionic nerve fibers that supply the muscularis mucosae.

Meckel's ganglion: better known as the sphenopalatine ganglion, which is a small parasympathetic ganglion in the upper part of the sphenomaxillary fissure giving off nerves to the eyes, nose, and palate.
