Brainstem Flashcards
Edinger-Westphal fxn
CN III
ciliary ganglion –> sphincter pupillae/ciliaris muscles
pupillary constriction and accommodation
Superior salivatory nucleus fxn
CN VII Pterygopalatine ganglion Submandibular ganglion --> lacrimal gland/salivatory glands secretion of tears/stimulate salivation
Inferior salivatory nucleus fxn
CN IX
Otic ganglion –> parotid gland
stimulate salivation
Nucleus ambiguus fxn
CN X
thoracic visceral plexus –> heart
decrease HR
Dorsal motor nucleus of vagus fxn
CN X
thoracic visceral plexus –> thoracic/abdominal viscera
constrict airways and stimulate digestion
Lateral horn at S2-4 fxn
Pelvic splanchnic nerves
paravertebral plexus –> pelvic viscera
bladder/bowel/sexual fxn
