cranial nerves and important Brodmann numbers Flashcards
what type of nucleus is the oculomotor?
general somatomotor
dorsomedial location (in brainstem)
what type of nucleus is the accessory oculomotor (edinger westphal)?
general visceromotor
parasymp
what type of nucleus is the trochlear?
general somatomotor
dorsomedial
what type of nucleus is the motor trigeminal? what does it affect?
special visceromotor or brachiomotor
ventrolateral motor
control of the muscles of mastication
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
what type of nucleus is the principal pontine trigeminal? what sort of sensation and where?
general somatosensory
epicritic sense of head
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
what type of nucleus is the abducent?
general somatomotor
dorsomedial
what type of nucleus is the facial?
special visceromotor or brachiomotor
ventrolateral
what type of nucleus is the superior salivatory? come from which nerve?
general visceromotor
from facial nerve
what type of nucleus is the solitary tract? comes from which nerves?
special viscerosensory
(taste)
from facial, glossopharyngeal, and vagus
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
what type of nucleus is the inferior salivatory? what nerve makes is?
general visceromotor
parasymp
from glossopharyngeal nerve
what type of nucleus is the lateral ala cinerea? which nerves contribute?
general viscerosensory
glossopharyngeal and vagus
what type of nucleus is the cochlear? what are the names of the nuclei?
special somatosensory
dorsal and ventral nuclei
what type of nucleus is the vestibular?
what are its parts?
special somatosensory
medial, lateral, superior, inferior
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)
what type of nucleus is the hypoglossal?
somatomotor
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
brodmann number of the motor cortex?
4, 6
brodmann number of the sensory cortex?
3, 1, 2
brodmann number of the primary auditory cortex? Heshl’s area
41, on transverse temporal gyrus
brodmann number of the primary visual area? also known as?
17
gennari stria or area striata
brodmann number of the secondary visual area?
18
brodmann number of the tertiary visual area?
19
brodmann number of the wernicke sensory speech area?
39, 40
brodmann number of the broca motor speech area?
44, 45
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
- Cerebellothalamic & Rubrospinal Tracts
- Lenticular Fascicle
- Lenticular Ansa
Located between Zona Incerta and Thalamus
What are the contents of Forel’s H2 field?
Where is it?
Lenticular Ansa
Located between Zone Incerta and Subthalamic Nucleus of Luysi
