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

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

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

26
brodmann number of the wernicke sensory speech area?
39, 40
27
brodmann number of the broca motor speech area?
