Flashcards in Brainstem Deck (17):
1

Edinger-Westphal fxn

CN III
ciliary ganglion --> sphincter pupillae/ciliaris muscles
pupillary constriction and accommodation

2

Superior salivatory nucleus fxn

CN VII
Pterygopalatine ganglion
Submandibular ganglion
--> lacrimal gland/salivatory glands
secretion of tears/stimulate salivation

3

Inferior salivatory nucleus fxn

CN IX
Otic ganglion --> parotid gland
stimulate salivation

4

Nucleus ambiguus fxn

CN X
thoracic visceral plexus --> heart
decrease HR

5

Dorsal motor nucleus of vagus fxn

CN X
thoracic visceral plexus --> thoracic/abdominal viscera
constrict airways and stimulate digestion

6

Lateral horn at S2-4 fxn

Pelvic splanchnic nerves
paravertebral plexus --> pelvic viscera
bladder/bowel/sexual fxn
