Vestib and CN
NPTE
| Question | Answer |
|---|---|
| Tinnitus is a symptom with which vestibular disorder? | Peripheral vertigo |
| Menieres would be an example of central or peripheral vertigo? | Peripheral |
| Central or peripheral vertigo presents with autonomic symptoms? | Peripheral - pallor, sweating, n/v |
| diplopia and hemianopsia are symptoms associated with what type of vertigo? | central - along with other neurological symptoms (dysarthria, ataxia, weakness and numbness) |
| Migraine is an example of central or peripheral vertigo? | Central |
| Give 4 examples of pathologies associated with central vertigo | Migraines, MS, trauma/tumor, cerebellar degeneration |
| Give 4 examples of pathologies associated with peripheral vertigo | BBPV, Menieres, trauma/tumor, DM |
| Visual fixation inhibits nystagmus and verigo with what type of vestibular disorder? | Peripheral |
| Corneal Reflex | CN 5 (trigeminal) and 7 (facial) 5 = sensory, 7 = motor normal response: blink when cornea is touched with a cotton ball |
| Gag Reflex | CN 9 (glossopharyngeal) and 10 (vagus) |
| Uvula deviation | CN 9 (glossopharyngeal) |
| How do you test for facial cranial nerve? | anterior 2/3 taste, facial expression muscles |
| CN 9 testing | Glossopharyngeal - taste on posterior 1/3 of tongue, Uvula deviation and Gag reflex |
| CN 8 testing | Vestibulochoclear - Acoustic testing, Weber test with tuning fork |
| CN 10 testing | Vagus - Gag reflex. Parasympatheric motor fibers: HR, sweating, speech |
| CN 12 | Hypoglosal - tongue protruision (deviates away from lesion) |
| CN 11 | Spinal Accessory - UT MMT |
| CN 3 | Oculomotor - all eye movements except ABD (CN6) and down and in (CN4). Pupil constriction, raise eye lid |
| Pupil Reflex | CN 2 and 3. Shine a light into one eye (block with your hand). Ipsilateral pupil should constrict followed by contralateral |
| What CN is affected if only the ipsilateral pupil constricts during pupillary reflex testing? | CN 3 - oculomotor |
| What CN is affected if neither pupil constricts during pupillary reflex testing? | CN 2 - optic |
| CN 4 | Trochlear - down and in: superior oblique (LR6SO4) |
| CN 6 | Abducens: eye ABD: lateral rectus (LR6SO4) |
| CN 2 | optic - visual acuity (eye chart) |
| What is visual extinction and what CN is being tested? | CN 2 (optic), pt can only detect the finger when it is presented simultaneously with the other, they will not be able to detect it when it is presented alone. |
| CN 5 | Trigeminal - Sensory of face and motor for temporalis and masseter |
| V1 | opthalamic sensation |
| V2 | Maxillary sensation |
| V3 | Mandible sensation |
