Parasympathetic ganglion

From Biology-Online Dictionary | Biology-Online Dictionary


noun, plural: parasympathetic ganglia

Any of the ganglia of the parasympathetic nervous system, consisting of nerves that arise from the cranial and sacral regions of the spinal cord.


Examples of parasympathetic ganglia are the juxtamural ganglia, intramural ganglia and the four paired parasympathetic ganglia of the head and neck (i.e. ciliary ganglion, pterygopalatine ganglion, submandibular ganglion, and otic ganglion).

The parasympathetic ganglia are usually located close to or within the effected organs or tissues compared with the sympathetic ganglia that are located at a more distant site from the target organs.
