Question Answer
long PREGANGLION neuronparasympathetic layout
long POSTGANGLION neuronsympathetic layout
preganglionic neurons parasympatheticcranial 3,7,9,10 sacral 2-4

Section 2

Question Answer
terminal gangliaclose to target tissue ciliary pterygopalatine otic submandibular
intramural gangliain target tissue

Section 3

Question Answer
ciliary ganglioNthrough oculomotor nerve smooth muscle of eye pupil constriction & visual accomodation
pterygopalatine ganglionthrough facial nerve innervates lacrimal ducts nasal mucosa ^secretion
submandibular ganglionfacial nerve inv. submandibular salivary glands ^ saliva
otic ganglionthrough glossopharyngeal nerve inv. parotid salivary glands ^ secretion
intramural ganglion 1through vagus nerve innervates cardiac muscle lower heart rate; bronchoconstriction; contract smooth muscle in gi tract; loosen sphincters ; ^ gland secretion
intramural ganglion 2through pelvic nerves smooth muscle in urinary tract contract muscle relax sphincters ^ urinary activity.
