Q

How do you test function of muscles of mastication?

A

Close jaw, palpate superficial jaw closers (tempralis and master)

Open jaw against resistance, see if chin deviates to side of lesion (crushed can)

Q

What motor defects if V3 at foramen ovale?

A

Hyperacusis caused by loss of tensor tympani

Nasal speech, regurgitation into nasopharynx while swallowing bc loss of tensor veli palatine muscle in soft palate

*hearing balance not affected

17
Q

What deficit if lesion immediately to facial canal?

A

Facial palsy, taste anterior 2/3 tongue, salivary gland to floor of mouth, skin, hyperacusis, dry eyes, nasal cavity palate, LOSS OF HEARING BALANCE

18
Q

What nerve innervates the parotid gland?

A

CNIX glossopharyngeal nerve

19
Q

What innervates all the motor muscles of the larynx, palate, upper esophagus EXCEPT tensor veli palatine and stylopharyngeus muscle? What innervates the later?

A

CNX

TVP-> V3 (VP -> V3)
Stylo->IX

20
Q

What nerve has a lesion if nasal speech and liquids in nasal cavity when swallowing. When at rest, soft palate and uvula seem to deviate to right. When contraction, deviates to the right. What side?

A

Lesion in LEFT vagus nerve or LEFT mandibular division of trigeminal

21
Q

What are the afferent and efferent limbs of the gag reflex?

A

Afferent limb -> CNIX

Efferent ->CNX

22
Q

If wooden tongue blade is touched to mucosa on one side of the pharynx of patient, what response?

A

Symmetrical gag response/constrictio

23
Q

If wooden tongue blade touched to EITHER side of the pharynx with damaged right vagus, what response?

A

Left side constricts, asymmetrical gag response with deviation to left

24
Q

What are the afferent and the efferent limbs of the cough reflex?

A

Afferent: CNX (superior/inferior laryngeal nerve)

Efferent: CNX, phrenic, abdominopelvic

25
Q

What nerve is injured if tongue deviates to left when at rest and deviates to right when protruded?

A

Right hypoglossal nerve?
