Cranial Nerves And Electorde Placement Flashcards
First cranial nerve
Olfactory (sensory)
Second cranial never
Optic (sensory)
3rd cranial nerve
Oculomotor (motor)
4th cranial nerve
Trochlear (motor)
What does 4th cranial nerve do?
Eye movement, superior oblique muscle (up and down)
Fifth cranial never
Trigeminal (opthalmic, maxillary and Mandibular)
Both
Where to place electrodes to monitor trigeminal nerve
Forehead/temple- opthalmic branch
Cheeks- maxillary branch
Chin- mandibular branch
Which branch of tirgmeinal is both sensory and motor and why’s this improtnsnt
Mandibular -> bite block
6th cranial nerve
Abducens- motor
Where to place electrodes to monitor 6th cranial nerve
Side of eyes (lateral eye movement)
7th nerve
Facial (both)
Where to place electrodes for facial nerve monitoring
Frontalis muscle (forehead)
Orbicularis oculi muscle (temple)
Orbicularis Oris muscle (above mouth)
Mentalis muscle (below mouth)
Ground on chest
8th cranial nerve
Vestibulocochelar (sensory)
Where to place electrodes for cranial nerve 8
In ears (clicking stimulation)
