Question 1

Parts of ALS

Answer 1

Neospinothalamic= fibers to S1, S2 for LOCALIZATION
Paleospinothalamic= spinoreticular--> anterior cingulate and insular cortex

Question 2

What makes you MAD when you get hurt?

Answer 2

Paleospinothalamic= spinoreticular

Question 3

Spinomesencephalic

Answer 3

Mesencephalic= midbrain PAG

MODULATION OF PAIN

Question 4

5 parts of ALS

Answer 4

1. Spinothalamic
2. Spinoreticular
3. Spinomesencephalic
4. Spinobulbar
5. Spinohypothalamic

Question 5

spinobulbar

Answer 5

spino-olivary

Bulbo= olivary

Question 6

spinohypothalamic

Answer 6

Autonomic expression of pain

Question 7

Medial motor

Answer 7

Axial muscles

Question 8

Medial motor- what influences this region

Answer 8

Proprioception synapses here

Reticulospinal, vestibulospinal, anterior corticospinal

Question 9

What affects sympathetics

Answer 9

hypothalamospinal fibers

Question 10

What synapses in Lamina II

Answer 10

Raphe- carry serotonergic

Question 11

What part of hypothalamus sends input to sympathetics

Answer 11

paraventricular

Question 12

Parabrachial nucleus

Answer 12

“whitish between the black”

spinoreticular tract. motivation/emotional aspect of pain

Question 13

DRG above C6?

Answer 13

accessory cuneate nucleus–> vermis granule layer

Question 14

Descending MLF

Answer 14

(below abducens)–> spinal cord to cervical region medial neurons. Bilateral projections

Question 15

Ascending MLF

Answer 15

to eye muscles

Question 16

Restiform body

Answer 16

Cuneocerebellar
(clarke’s nucleus is equivalent in lower area)
Bodies in accessory cuneate nucleus and clarke’s nucleus

Question 17

Olivo cerebellar

Answer 17

climbing fibers to purkinje cells

Question 18

Neurosyphilis

Answer 18

wipes out pretectal region (light reflex) but WONT affect conversion (pupil WILL constrict to that).

Question 19

Smooth pursuit

Answer 19

vestibular nuclei to CN III

Question 20

Vestibular nuclei control

Answer 20

VOR and smooth pursuit to CN III

Question 21

Horizontal gaze

Answer 21

abducens

Question 22

convergence

Answer 22

supraculomotor area (to medial rectus AND EDW)

Question 23

pretectal region

Answer 23

light reflex

Question 24

Modality means?

Answer 24

pain temp crude touch fine touch vibration etc

Question 25

Ventral trigeminal tract carries

Answer 25

Pain, temp, crude touch from FACE in medulla, in pons/midbrain it gains fibers from principal trigeminal tract

Question 26

Raphe magnus- releases? axons travel?

Answer 26

serotonin, travel to lamina 2 and 3 (post horn) + spinal trigeminal nucleus

Question 27

Juxtarestiform body comes from?

Answer 27

Bodies in cerebellar fastigial nucleus and vestibular nuclei.
Has Efferent and afferent cerebellar fibers

Question 28

junctional lesion

Answer 28

eye track before chiasm

Question 29

Mesencephalic tract projects where? what reflex?

Answer 29

jaw jerk

–> motor V, VPM, and cerebellum, RF

Question 30

RF around abducens =

Answer 30

PPRF= horizontal gaze center

Question 31

Input TO horizontal gaze is

Answer 31

FEF and superior colliculus

Question 32

FEF controls

Answer 32

memory mediated movement

Question 33

SUP colliculus medieats

Answer 33

behavior reflexive movements

Question 34

Supraoculomotor does?

Answer 34

convergence

Question 35

Brachium of superior colliculus?

Answer 35

Retinal ganglion cells that DONT get off at LGN

Fx: blind sight, light reflex,

Question 36

paraventricular=

Answer 36

ADH+ oxytocin; and autonomics

Question 37

supraoptic

Answer 37

only ADH
