Flashcards in cranial nerves and important Brodmann numbers Deck (29):
1

what type of nucleus is the oculomotor?

general somatomotor

dorsomedial location (in brainstem)

2

what type of nucleus is the accessory oculomotor (edinger westphal)?

general visceromotor

parasymp

3

what type of nucleus is the trochlear?

general somatomotor

dorsomedial

4

what type of nucleus is the motor trigeminal? what does it affect?

special visceromotor or brachiomotor

ventrolateral motor

control of the muscles of mastication

5

what type of nucleus is the mesencephalic trigeminal? what sort of sensation and where?

general somatosensory

proprioceptive sense in the head

note: ganglion cell is in cns as a pseudounipolar ganglion

6

what type of nucleus is the principal pontine trigeminal? what sort of sensation and where?

general somatosensory

epicritic sense of head

7

what type of nucleus is the spinal trigeminal? what sort of sensation and where? which nerves also supply this spinal trigeminal nuclei?

general somatosensory protopathic sense of head

note: this nucleus receives fibers from nerves 5, 7, 9 and 10 since they all supply the face and help it feel pain i guess

8

what type of nucleus is the abducent?

general somatomotor

dorsomedial

9

what type of nucleus is the facial?

special visceromotor or brachiomotor

ventrolateral

10

what type of nucleus is the superior salivatory? come from which nerve?

general visceromotor

from facial nerve

11

what type of nucleus is the solitary tract? comes from which nerves?

special viscerosensory

(taste)

from facial, glossopharyngeal, and vagus

12

what type of nucleus is the ambiguus? which nerves contribute to this nucleus?

special visceromotor or brachiomotor

ventromedial

9, 10, 11 make up the nucl ambiguus

13

what type of nucleus is the inferior salivatory? what nerve makes is?

general visceromotor

parasymp

from glossopharyngeal nerve

14

what type of nucleus is the lateral ala cinerea? which nerves contribute?

general viscerosensory

glossopharyngeal and vagus

15

what type of nucleus is the cochlear? what are the names of the nuclei?

special somatosensory

dorsal and ventral nuclei

16

what type of nucleus is the vestibular?

what are its parts?

special somatosensory

medial, lateral, superior, inferior

17

what type of nucleus is the accessory?

 

where else do fibers originate for this nerve?

general somatomotor

dorsomedial

the motor fibers also originate from c 1-6 (spinal root of accessory nerve)

18

what type of nucleus is the hypoglossal?

 somatomotor 

19

which nerves contribute to the spinal trigeminal nucleus?

5, 7, 9, 10

they all have protopathic function but do not have their own nuclei just for this so their protopathic fibers all terminate on the spinal trigeminal nucleus

20

brodmann number of the motor cortex?

4, 6

21

brodmann number of the sensory cortex?

3, 1, 2

22

brodmann number of the primary auditory cortex? Heshl's area

41, on transverse temporal gyrus

23

brodmann number of the primary visual area? also known as?

17

gennari stria or area striata

A image thumb
24

brodmann number of the secondary visual area?

18

25

brodmann number of the tertiary visual area?

19

26

brodmann number of the wernicke sensory speech area?

39, 40

A image thumb
27

brodmann number of the broca motor speech area?

44, 45

A image thumb
28

What are the contents of Forel's H1 field?

 

Where is it?

The Thalamic Fascicle: All 3 of the contents from the different H fields we need to know

 

  1. Cerebellothalamic & Rubrospinal Tracts
  2. Lenticular Fascicle
  3. Lenticular Ansa

Located between Zona Incerta and Thalamus

 

29

What are the contents of Forel's H2 field?

 

Where is it?

Lenticular Ansa

 

Located between Zone Incerta and Subthalamic Nucleus of Luysi
