Olfactory Sensory from olfactoryreceptors in nasal cavitySmell testsII. Optic Thru optic canal into orbitSensory from retina of eye Tests of visionIII. Oculomotor Motor (mixed) to external eyemuscleadjustment and focusing of lensPatient asked to track a finger, check papillary reflexesIV. Trochlear Patient asked to track a finger down andlaterally
Slide5CRANIAL NERVES 5- 7
V.
Trigeminal
Mixed – sensory from face,mouth, teethMotor to muscles of masticationClench jaw, use cotton swab to lightly touchface for sensationVI. Abducens Mixed to external eye muscle Track finger movement laterallyVII. Facial Mixed to facial muscles,Autonomic to glands of face includingsalivary glandsPatient asked to use muscles of facialexpression, taste test
Slide6CRANIAL NERVES 8-12
VIII.
Vestibulocochlear Sensory from hearing andbalance receptors TEST: Check hearing and balanceXI. Glossopharyngeal Mixed –motor to salivary gland, somatic motor to pharynx TEST Check gag reflexX. Vagus - major parasympathetic nerve to thoracic and abdominalviscera controlling “rest and repose” response TEST: Check swallowing reflexXI. Accessory Mixed – mostly motor to muscles of neck and scalpTurn head against resistance or shrug-STERNOCLEIDOMASTOIDXII. Hypoglossal Mixed – mostly motor to muscles of tongue for speech, swallowingPatient tongue thrust should be straight
