Question 1

GPi projects to which thalamic nuclei?

Answer 1

ventral lateral

Question 2

which thalamic nuclei has no connections outside the thalamus?

Answer 2

Reticular

Question 3

what runs through foramen spinosum

Answer 3

MMA

Question 4

where does CN V enter the skull and with what?

Answer 4

jugular foramen, CN IX, XI, CN X - pass through neck of the jug

Question 5

pain and touch segment of trigeminal nucleus vs proprioception vs fine touch

Answer 5

spinal trigeminal nucleus-pain/temp
(spine-painful; cheif/priciple sensory - only fine touch)

mesencephalic - proprioception (words with similar length)

chief/principle sensory nucleus - fine touch

Question 6

foramen spinosum vs ovale vs rotundum vs lacerum

Answer 6

spinosum: most lateral and posterior
ovale - medial to spinosum - MMA

rotundum - anterior to spinosum - V2

lacerum - most medial, next to clivus - ICA

Superior orbital fissure - V1, III, IV, VI

Question 7

pathway bringing taste sensation from solitarius to VPM in thalamus

Answer 7

central tegmental tract

Question 8

where are cell bodies of cochlear hair cells?

Answer 8

spiral ganglia in temporal bone

Question 9

inferior vs superior salivatory nuc

Answer 9

inferior - parotid gland - CN IX -lesser petrosal N

superior - greater petrosal - CN VII

Question 10

facial N lesion localization

Answer 10

loud sound - btw genicular ganglion + stapedius nerve

branches facial nerve - 1st greater petrosal (parasympathetics to pterygopalatine ganglion)
-2nd branch stapedius nerve
-3rd branch chorda typani

after the geniculate ganglion: intact lacrimation

Answer 11

ataxia telangiectasia
high AFP

fingolimod side effect

Answer 12

bradycardia

Question 13
