| CN IV | Trochlear nerve |
| CN V | Trigeminal nerve |
| CN VI | Abducens nerve |
| CN VII | facial nerve |
| CN VIII | Vestibulocochlear (Acoustic) nerve |
| CN IX | Glossopharyngeal nerve |
| CN X | Vagus nerve |
| CN XI | Spinal Accessory nerve |
| CN XII | Hypoglossal nerve |
| On old olympus towering tops a Fin and german vending a hops | olfactory, optic, oculomotor, trochlear, trigeminal, abducens, facial, vestibulocochlear, glossopharyngeal, vagus, spinal accesory, hypoglossal. |
| Which CN carries impulses for smell? | CN I- olfactory |
| Which CN carries impulses for vision? | CN II- Optic |
| Which CN controls eyeball, eyelid, iris, ciliary body and sensory to brain from extraocular muscles? | CN III-oculomotor |
| Which CN controls superior oblique muscles of the eye? | CN IV- trochlear |
| What CN is involved in motor and sensory for face & conducts impulses from mouth, nose, surface of eye and dura mater? It also stimulates chewing muscles? | CN V- Trigeminal |
| What CN contains motor and proprioceptor fibers to lateral rectus muscle? | CN VI- abducens |
| What CN carries sensory fibers from taste buds of anterior part of tongue? | CN VII Facial |
| What CN is involved in facial expression? | CN VII facial |
| The facial nerve is involved with facial expression,anterior taste buds, and.... | supplies motor fibers to muscles of lacrimal and salivary glands. |
| Which CN is involved in hearing and equilibrium? | VIII vestibulocochlear |
| what is the other name for the vestibulocochlear nerve? | VIII acoustic- tested with tuning fork |
| which CN is involved with the posterior taste buds of the tongue? | IX Glossopharyngeal nerve |
| Which CN is associated with motor fibers that serve the throat & salivary glands, sensory fibers that serve pharnyx back taste buds, and pressure receptors for carotid artery? | IX Glossopharyngeal nerve |
| Which CN is carries sensory & motor impulses for pharnyx and is largely parasympathetic motor fibers that serve ABD organs smooth muscle? Also receives sensory imulses from viscera. | X vagus |
| Word association= V- visceral | V- vagus |
| What CN carries motor fibers to tongue and sensory from tongue to brain? | XII- Hypoglossal |
| Provides sensory & motor fibers to sternocleidomastoid and trapezius muscles? | XI- spinal accessory |
| Also provides motor & sensory fibers to muscles of soft palate pharynx, and larynx. | XI- spinal accessory |
| cranial nerves are categorized as | peripheral nerves |
| Cramial nerves arise from... | nuclei in the brain and brain stem |
| Take a sniff and test your... | olfactory nerve |
| Take a look at my eye chart and my finger to test your... | optic nerve |
| Your pupils will teach me a thing or 2 about your | oculomotor nerve ( ability to follow moving objects tests also) |
| Follow my finger and poof... | your trochlear is being tested. ( similar testing to CN III) |
| Trigeminal tested by | corneal reflex, motor branch test |
| 3 CN tested in similar way by following objects with eye laterally. whic R they? | III, IV, VI |
| Stick out your tongue and say ahhhhh.... | hmmm checking your hypoglossal. look for position abnormalities of tongue |
| IX and X are tested in common by... | checking gag & swallow reflexes. speak & cough. FOr IX posterior of tongue may check taste buds. |
| Facial check | check- anterior taste buds, face symmetry Do- close eyes, smile, whistleetc. tearing test. |
| spinal accessory checked by | rotate head and shrug shoulders against resistance |
