Cranial nerve nuclei Flashcards
what are 3 ways CNs are diff than spinal nerve/column
- functional columns in series of distinct columns
- CNs may carry only a single modality
- some CN have “special senses”
what are the 8 voluntary motor nuclei
- occulomotor
- troclear
- abducens
- hypoglossal
- masticator
- facial
- nucleau ambiguous
- accessory
what are targets and axons of occulomotor
targets: lev palpebrai, SR, IR, MR, IO
axons: contributre to CN3
what are targets and axons of troclear
targets: SO
axons: form CN 4
what are targets and axons of abducens
targets: LR
axons: form CN6
what are targets and axons of hypoglossal
targets: tongue muscles
axons: forms 12
what are targets and axons of masicator
targets: muscles of mastication
axons: contributes to V
what are targets and axons of facial
targets: fascial movement
axons: cont. to VII
what are targets and axons of ambiguous
targets: laryngeal and pharyngeal
axons: cont. to CN IX and X
what are targets and axons of accessory
targets: shoulder muscles
axons: forms 11
what are 4 parasymp. nuclei
- edinger westphal
- superior salvatory
- inf. salvatory
- dorsal vagal
what are targets and axons of edinger westphal
targets: inv. muscles of eye
axons: joins III
what are targets and axons of sup. salivatory
targets: lacrimal, sublingual, submandibular glands and mucosa
axons: joins VII
what are targets and axons of in mandibular
targets: parotid
axons: joins IX
what are targets and axons of dorsal vagal
targets: gut para
axons: joins X
