Q

5 branches, temporal, zygomatic, buccal, mandibular, cervical

A

facial

22
Q

sense of taste is what portion of the tongue

A

anterior 2/3

23
Q

motor to muscle of facial expression

A

facial

24
Q

parasympathetic fibers to submandibular and sublingual salivary glands, lacrimal gland, nasal cavity, palate glands

A

facial

25
Q

facial nerves test for

A

taste, check facial symmetry, assess tearing

26
Q

damage to facial nerve results in

A

facial palsy, lose taste, decreased salivation

27
Q

sense of hearing and balance

A

vestibulocochlear

28
Q

parasympathetic fibers to sphincter pupillae=

A

pupil restriction

29
Q

what does vestibulocohlear test for

A

air and bone conduction via tuning fork

30
Q

damage to vestibulocochlear results in

A

loss of hearing, loss of balance

31
Q

sensory to taste

A

glossopharyngeal

32
Q

posterior 1/3 tongue

A

glossopharyngeal

33
Q

general sensory (pain, touch, pressure)
impulses from pharynx, posterior tongue, from chemoreceptors carotid body

A

glossopharyngeal

34
Q

how do you test the glossopharyngeal

A

check ulva position, gag/swallow reflex, speak and cough

35
Q

what happens when the glossopharyngel is damaged

A

impaired swallowing and taste, decreased salivation

36
Q

impulses from baroreceptors carotid sinus. motor to pharyngeal muscle

A

glossopharyngeal

37
Q

longest cranial nerve

A

vagus

38
Q

what nerve goes into thoracic and abdominal cavities

A

vagus

39
Q

sensory from thoracic and abdominal viscera, aoritic arch baroreceptors, carotid and aoritic bodies chemoreceptors. taste buds

A

vagus

40
Q

motor to skeletal muscles of pharynx and larynx

A

vagus

41
Q

parasympathetic motor fibers to heart, lungs, abdominal viscera for HR, RR, digestive activity

A

vagus

42
Q

what do you use to test the vagus nerve

A

CNIX

43
Q

damage to vagus nerve results in

A

vagal nerve paralysis
difficulty swallowing
hoarseness
ulva deviates from side of dysfunction
impaired digestive motility

44
Q

cranial rootlets from CNX, not brain/ passes through the skull

A

accessory

45
Q

motor to sternocleidomastoid and trapezius move head and neck

A

accessory

46
Q

test strength by elevating shoulders, rotation of neck

A

accessory

47
Q

damage to accessory nerve results in

A

difficulty shrugging shoulders, rotation of neck against resistance. head turns towards side of injured nerve

48
Q

motor to tongue and throat muscles

A

hypoglossal

49
Q

swallow and speech

A

hypoglossal

50
Q

positions food between teeth to chew, then moves through tongue out of the way

A

hypoglossal

51
Q

how do you test the hypoglossal nerve

A

protusion and retraction of tongue, should be midline

52
Q

damge to hypoglossal means

A

tongue deviates toward side of damaged nerve, both= cannot protrude
