cranial nerves Flashcards
the only SSA nucleus
vestibulocochlear
vestibulocochlear locale
pons/medulla
the only SVA/GVA nucleus
solitary nucleus
solitary nucleus locale
medulla/spinal cord
rostral part of solitary nucleus is for what sense
taste; SVA
caudal part of solitary nucleus is for what function/CN
cardiovascular control; CN 9-10; GVA
three CNS that have an alternating hemiplegia
CN 3, 6, 12
nerves and locale of spinal trigeminal
5,7,9,10; it stretches from pons thru medulla to the spinal cord; GSA
two nuclei for CN3
occulomotor complex (midbrain-GSE); edinger-westphal (midbrain-GVE)
only nuclei for CN 6
abducens (pons-GSE)
4 nuclei for CN 5
motor trigeminal (pons-SVE); mesencepphalic (midbrain-GSA); principal sensory (pons-GSA); spinal trigeminal (Pons to cord-GSA)
only nuclei for CN 4
trochlear (midbrain-GSE)
4 nuclei for CN 7
sup. salvitory (pons-GVE); facial (pons-SVE); solitary (medulla and cord-SVA/GVA); spinal trigeminal (pons to cord-GSA)
only nuclei for CN 8
vestibulocochelar (pons/medulla-SSA)
4 nuclei for CN9
inf. salvitory (medulla-GVE); nucleus ambiguus (medulla-SVE); solitary (medulla/cord-SVA/GVA); spinal trigeminal (pons thru cord-GSA)
4 nuclei for CN10
dorsal motor (medulla-GVE); nucleus ambiguus (medulla-SVE); solitary nucleus (medulla/cord-SVA/GVA)
only nuclei for CN 11
accessory (cord-GSE)
only nuclei for CN 12
hypoglossal (medulla-GSE)
tongue vs uvula deviation
tongue deviates toward a PERIPHERAL LESION, or away from a CENTRAL LESION
what are the GSE nerves and nuclei
occulomotor,3; trochlear,4; abducens,6; hypoglossal,12; accessory,11
what are the SVE nerves and nuclei
motor trigem,5; facial,7; ambiguus, 9-10
what are the GVE nerves and nuclei
edinger-westphal,3; sup. salvitory,7; inf. salvitory, 9; dorsal motor, 10

somatomotor CNs
3,7,9,10,11,12; these to muscles, their nuclei are located near midline
CNs that are only sensory
1,2,8
inferior alternating hemiplegia injures?
the corotcospinal fibers in the pyramid of the medulla, medial lemniscus and hypoglossal
middle alternating hemiplegia injures?
corticospinal fibers in basilar pons and abducens
superior alternating hemiplegia injures?
corticospinal fibers and occulomotor
