To test CN5 what 2 things do you do?
** Corneal reflex is also tested and the sensory input is through CN ___ and the output motor is through CN ___*****
Check sensation to the face and motor innervation for muscles of mastication
5, 7
For the motor innervation of the mastication muscles, you should palpate the ___ and ___ muscles, and then ask patient to clench their ___ and move ___ side to side in order to test ___
A unilateral weakness would indicate a ___ lesion, and a bilateral weakness would indicate a ___ disease
*To test sensory to the face for CN 5, you can do pain, temp, our light touch to the forehead, cheeks and jaw
If there is a cortical or thalamic lesion, facial sensory loss will be on the ___ side of the lesion and body sensory loss will be on the ___ side of the lesion
^**EX: Left cortical or thalamic lesion = R facial and R body sensory loss
If there is a brainstem lesion, facial sensory loss will be on the ___ side of the lesion and body sensory loss will be on the ____ side of the lesion

Isolated facial sensory loss (no body loss) occurs in peripheral disorders like ____

To test CN7 what 2 thing do you do?
Taste to anterior 2/3rds and motor innervation to muscles of facial expression
To test the motor innervation for the muscles of facial expression, you can have them raise ___, smile, frown, pucker ___, close eyes tightly, and purse lips
A lesion to the facial nerve can result in ___ and this would cause a loss of taste to the ___ of the tongue (affects upper and lower face)
^**A central lesion such as in a stroke affects mainly the ___ face
^** So realize that if the peripheral nerve affected is (like in bells palsy), the ENTIRE face will be affected, if it is going to the nucleus aka central facial palsy, you will only see the LOWER half affected (like in a stroke aka supranuclear facial palsy)
^** So once again, if you can raise ur eyebrows but face is droopy… The lower half of ur face is affected aka a central facial palsy****
*To test sensory innervation, have patient taste something
___ can be tested for via secretion of saliva and tears
Eyebrows, cheeks
Bell’s palsy, anterior 2/3rds
lower
Parasympathetics
To test CN8 (vestibulocochlear) what 3 thing do you do for the cochlear division?
So once again, cochlear division tests ___ and vestibular division tests ___
**Tests for hearing and includes the Whisper test, Weber’s test, and Rinne’s test
** Vestibular division tests balance, and it is often not included in the exam
Hearing, balance
First conduct the whisper test or finger rub test in order to determine if hearing loss is present
If there is, one conducts the weber’s test to look for ___ damage or ___.
This is done by striking a tuning fork and placing it in the middle of the patients forehead and diminished tone in the affected ear indicates ___ loss and a louder tone in the affected ear indicates ___ deafness
The ___ test checks air and bone conduction and confirms the presence of conduction deafness in the affected ear and this is done by placing the tuning fork on the ___ and then when tone is gone, place it over the external auditory meatus and if the patient can’t hear the sound, then conduction deafness is present
Sensorineural or lateralization
Sensorineural, conductive
Rinne’s, Mastoid process
The gag reflex tests CN __ and ___ together and CN 9 is the ___ portion of the reflex and CN 10 is the ___ portion of it
9 and 10, sensory, motor
The only muscle CN 9 innervates is the ___ muscle and this aids in swallowing
CN 9 also supplies taste to the ___terior __/___ of the tongue
Stylopharyngeus, posteiror 1/3
However unlike CN 9, which a lesion results in loss of gag reflex, loss of sensation to posterior 1/3rd of tongue, and slight dysphagia (difficulty swallowing)… CN 10 results in loss of gag OR ___ reflex, ____, dysphagia, and dyspnea
^** One can test the vagus nerve via a water test, gag reflex, evaluating presences of hoarseness, or the inspecting palate and uvula symmetry
^** If uvula fails to rise, think bilateral lesion and if it deviates to one side, it is a unilateral lesion and the uvula is deviating ___ from the affected side (aka moves towards normal side)
Cough, dysphonia (hoarseness)
Away
To test CN11 what 2 thing do you do (one for each muscle)
Paralysis of the SCM results in difficulty turning head to the ___ side
^** AKA if you can’t turn your head to the right, the left SCM is messed up and therefore the lesion is on the left side
Weakness of the traps from a CN 11 lesion results in ___ shoulder drop
^** AKA if the right CN11 is damaged, the right shoulder will drop
Shrug shoulders (testing for traps) and turn head against resistance (testing for SCM)
Opposite
Ipsilateral
To test CN12 what 1 thing do you do?
Look for tongue symmetry
Since CN 12 innervates the intrinsic tongue muscles, if one were to have a lesion it would cause the tongue to deviate towards the ____ side (lick its wound)
