Flashcards in Myelins: Brainstem/spinal misc. Deck (15)
1

Where in the brainstem do you still have HRST?

Medulla

2

Where is HRST near in the medulla?

medial to spinal trigem nuclei/tract

3

What nuclei is in rostral medulla AND caudal pons?

vestibular nuclei.
spinal trigem nuclei/tract

4

what nuclei is just in the rostral midbrain

oculomotor

5

where is liussers tract until?

cervical region (there is none in the upper cervical)

6

where does rubrospinal appear? where is it near in the spinal cord?

- appears at lower lumbar

- next to lateral corticospinal tract then switches to next to HRST in upper cervical

7

What is important about the first thoracic slide?

HRST
Clarks
IML
and Dorsal Spinocerebellar tract

8

Where is clarks nucleus found?

just the thoracic slide

9

Describe where HRST is found in the spinal cord

starts at first thoracic

and stays in the indent until the upper cervical, where it switches with lateral corticospinal tract

10

what appears in upper cervical?

spinal nuclei and tract of 5 repelace lisseurs

11

where is hrst in the medulla?

medial to spinal nucleus and tract

12

where is rubrospinal in the medulla

below the spinal nucleus and tract

13

when does solitary nucleus, nucleus ambiguous, MLF, and emdial lemniscus appear in the medulla

after the decussation stays until vestibular cochlear nerve comes in

14

where is superior olive in the pons?

on top of the lateral lemnicus on the first 2 caudal sections of the pons

15

where is ALS and rubro in the ponS?

in the most caudal -- by the spinal nucleus and tract
in middle and rostral its on top of the medial lemniscus
