Brainstem 2

Question 1

first place with biaural innervation

Answer 1

superior olivary

Question 2

mossy fibers from pons innervate

Answer 2

granular cells

Question 3

trigeminal stuff is pretty much all

Answer 3

in the pons. principle sensory (fine touch of face) mesencephalic nucleus, and motor trigeminal nucleus

Question 4

juxtarestiform body

Answer 4

almost like its own little peduncle that sends vestibular fibers to cerebellum (flocculus and nodulus)

Question 5

vestibular system is linked to

Answer 5

CN 6, 4, 3 via the medial longitudinal fasciculus. this is so that when you turn your head left, you eyes can still look right

Question 6

jawjerk reflex tests

Answer 6

the mesencephalic (afferent) and the motor trigeminal (efferent)

Question 7

superior cerebellar peduncle is landmark for

Answer 7

middle of the pons; telling you that you are going through the trigeminal motor nucleus region

Question 8

muscle for CN 9

Answer 8

stylopharyngeus mm

Question 9

component of trigeminal motor nucleus

Answer 9

SVE

Question 10

principal sensory nucleus component and function

Answer 10

GSA; fine touch

Question 11

CN 5 goes through

Answer 11

the middle Cbellar peduncle

Question 12

blood supply to pons

Answer 12

basilar artery and branches: paramedian, short circumferential, long circumferential

Question 13

landmark for midbrain

Answer 13

periaquaductal gray, decussation of superior CBellar peduncle

Question 14

periaquaductal gray functions

Answer 14

freezing behavior with fight or flight, pain modulation, this is the opioid cell region

Question 15

where is the lateral lemniscus?

Answer 15

it hugs the inferior colliculus

Question 16

parapontine reticular formation

Answer 16

related to horizontal eye movements

Question 17

thalamogeniculate arteries

Answer 17

go to the core thalamus as well as the geniculate nucleus inside the thalamus (branch of PCA)
