nuclei

Question 1

edinger westphal nuclei

Answer 1

located in midbrain next to oculomotor nuclei

will provide the parasym to CN 3 for ciliary ganglion

Question 2

nuclei of brainstem dessucations

Answer 2

nuclei of the CNs on the same side as the structures they inn, although motor nn are from the opposite side of the cortex
sensory info will go to the same side nuclei before crossing over to the opposite side of the cortex

Question 3

salivary nuclei/ lacrimal nuclei

Answer 3

Both located in medulla
• Superior Salivary nucleus: CN7 Salivation/lacrimation
submandibular and sublingual gland via Submandibular ganglion
Lacrimal nuclei is with in Superior salivary
Lacrimal gland via pterygopalatine or sphenopalatine ganglion

• Inferior Salivary nucleus: CN9 Salivation
Parotid gland via Otic ganglion

Question 4

rostral nucleus of the solidarity tract

Answer 4

located in medulla
• Nucleus of the solitary tract: CN 7,9,10 taste
• Relays taste information in rostral portion (gustatory nuclei)

Question 5

ganglia of the face are often associated with what nerve’s branches

Answer 5

located near CN V branches

Question 6

ciliary ganglia

Answer 6

will act on the ciliary mm and pupillary mm (lens accommodation, dilation/constriction)
PS from CN 3 (pregang), sym from sup cervical chain ganglion (post gang)

Question 7

otic ganglion

Answer 7

controls the parotid gland
PS from the lesser petrosal of CN 9
S from the sup cervical chain ganglia

Question 8

tongue inn: taste, sensory, motor

Answer 8

Taste
ant 2/3: CN 7 
Post 1/3: CN 9
epiglottis/palate: CN 10
sensory
ant 2/3: CN 5 
post 1/3: CN 9
motor 
CN 12

Question 9

ANS basics

Answer 9

PNS: crainosacral, use Ach for both synapses
SNS: thoracolumbar, project to the head as postganglionic axons from the sup cervical chain ganglia, use Ach at first synapse then epi/NE

Question 10

sup cervical ganglion

Answer 10

associated with the ext carotid, site of pre and post ganglionic sym synapse
projects nn to hitch rides on vessels and go to ganglia
