1
Q

what type of nucleus is the oculomotor?

A

general somatomotor

dorsomedial location (in brainstem)

2
Q

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

A

general visceromotor

parasymp

3
Q

what type of nucleus is the trochlear?

A

general somatomotor

dorsomedial

4
Q

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

A

special visceromotor or brachiomotor

ventrolateral motor

control of the muscles of mastication

5
Q

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

A

general somatosensory

proprioceptive sense in the head

note: ganglion cell is in cns as a pseudounipolar ganglion

6
Q

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

A

general somatosensory

epicritic sense of head

7
Q

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

A

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
Q

what type of nucleus is the abducent?

A

general somatomotor

dorsomedial

9
Q

what type of nucleus is the facial?

A

special visceromotor or brachiomotor

ventrolateral

10
Q

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

A

general visceromotor

from facial nerve

11
Q

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

A

special viscerosensory

(taste)

from facial, glossopharyngeal, and vagus

12
Q

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

A

special visceromotor or brachiomotor

ventromedial

9, 10, 11 make up the nucl ambiguus

13
Q

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

A

general visceromotor

parasymp

from glossopharyngeal nerve

14
Q

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

A

general viscerosensory

glossopharyngeal and vagus

15
Q

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

A

special somatosensory

dorsal and ventral nuclei

16
Q

what type of nucleus is the vestibular?

what are its parts?

A

special somatosensory

medial, lateral, superior, inferior

17
Q

what type of nucleus is the accessory?

where else do fibers originate for this nerve?

A

general somatomotor

dorsomedial

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

18
Q

what type of nucleus is the hypoglossal?

A

somatomotor

19
Q

which nerves contribute to the spinal trigeminal nucleus?

A

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
Q

brodmann number of the motor cortex?

A

4, 6

21
Q

brodmann number of the sensory cortex?

A

3, 1, 2

22
Q

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

A

41, on transverse temporal gyrus

23
Q

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

A

17

gennari stria or area striata

24
Q

brodmann number of the secondary visual area?

A

18

25
Q

brodmann number of the tertiary visual area?

A

19

26
Q

brodmann number of the wernicke sensory speech area?

A

39, 40

27
Q

brodmann number of the broca motor speech area?

A

44, 45

28
Q

What are the contents of Forel’s H1 field?

Where is it?

A

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
Q

What are the contents of Forel’s H2 field?

Where is it?

A

Lenticular Ansa

Located between Zone Incerta and Subthalamic Nucleus of Luysi
