Flashcards in Brainstem 2 Deck (17):
1

first place with biaural innervation

superior olivary

2

mossy fibers from pons innervate

granular cells

3

trigeminal stuff is pretty much all

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

4

juxtarestiform body

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

5

vestibular system is linked to

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

6

jawjerk reflex tests

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

7

superior cerebellar peduncle is landmark for

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

8

muscle for CN 9

stylopharyngeus mm

9

component of trigeminal motor nucleus

SVE

10

principal sensory nucleus component and function

GSA; fine touch

11

CN 5 goes through

the middle Cbellar peduncle

12

blood supply to pons

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

13

landmark for midbrain

periaquaductal gray, decussation of superior CBellar peduncle

14

periaquaductal gray functions

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

15

where is the lateral lemniscus?

it hugs the inferior colliculus

16

parapontine reticular formation

related to horizontal eye movements

17

thalamogeniculate arteries

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