cranial nerves and important Brodmann numbers

Question 1

what type of nucleus is the oculomotor?

Answer 1

general somatomotor

dorsomedial location (in brainstem)

Question 2

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

Answer 2

general visceromotor

parasymp

Question 3

what type of nucleus is the trochlear?

Answer 3

general somatomotor

dorsomedial

Question 4

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

Answer 4

special visceromotor or brachiomotor

ventrolateral motor

control of the muscles of mastication

Question 5

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

Answer 5

general somatosensory

proprioceptive sense in the head

note: ganglion cell is in cns as a pseudounipolar ganglion

Question 6

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

Answer 6

general somatosensory

epicritic sense of head

Question 7

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

Answer 7

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

Question 8

what type of nucleus is the abducent?

Answer 8

general somatomotor

dorsomedial

Question 9

what type of nucleus is the facial?

Answer 9

special visceromotor or brachiomotor

ventrolateral

Question 10

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

Answer 10

general visceromotor

from facial nerve

Question 11

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

Answer 11

special viscerosensory

(taste)

from facial, glossopharyngeal, and vagus

Question 12

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

Answer 12

special visceromotor or brachiomotor

ventromedial

9, 10, 11 make up the nucl ambiguus

Question 13

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

Answer 13

general visceromotor

parasymp

from glossopharyngeal nerve

Question 14

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

Answer 14

general viscerosensory

glossopharyngeal and vagus

Question 15

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

Answer 15

special somatosensory

dorsal and ventral nuclei

Question 16

what type of nucleus is the vestibular?

what are its parts?

Answer 16

special somatosensory

medial, lateral, superior, inferior

Question 17

what type of nucleus is the accessory?

where else do fibers originate for this nerve?

Answer 17

general somatomotor

dorsomedial

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

Question 18

what type of nucleus is the hypoglossal?

Answer 18

somatomotor

Question 19

which nerves contribute to the spinal trigeminal nucleus?

Answer 19

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

Question 20

brodmann number of the motor cortex?

Answer 20

4, 6

Question 21

brodmann number of the sensory cortex?

Answer 21

3, 1, 2

Question 22

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

Answer 22

41, on transverse temporal gyrus

Question 23

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

Answer 23

17

gennari stria or area striata

Question 24

brodmann number of the secondary visual area?

Answer 24

18

Question 25

brodmann number of the tertiary visual area?

Answer 25

19

Question 26

brodmann number of the wernicke sensory speech area?

Answer 26

39, 40

Question 27

brodmann number of the broca motor speech area?

Answer 27

44, 45

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
