Q

palatoglossus OI

A

origin: median palatine raphe
insertion: lateral surface of tongue

19
Q

action of palatoglossus

A

elevates and arches tongue to soft palate, depressing soft palate toward tongue; forming sphincter, separating oral cavity from pharynx

20
Q

tongue deviates toward

A

hypoglossal nerve lesion; muscles weak on the side of the lesion, overpowered by normal muscles

21
Q

muscles of the pharynx are involved with

A

speaking, swallowing, and middle ear function

22
Q

the pharynx includes the

A

nasopharynx, oropharynx, laryngopharynx

23
Q

the stylopharyngeus muscle

A

elevates and widens pharynx

24
Q

(muscle of the pharynx) stylopharyngeus innervated by

A

glossopharyngeal nerve cnIX

25
Q

pharyngeal constrictors innervated by

A

pharyngeal plexus from the vagus nerve CN X

26
Q

action of constrictor muscles

A

deliver food bolus to esophagus

27
Q

superior constrictor origin:

A

pterygoid hamulus, mandible, and pterygomandibular raphe

28
Q

where do all 3 constrictor muscles insert into

A

median pharyngeal raphe

29
Q

what do muscles of the soft palate form

A

palate posterior to the bony portion

30
Q

what are the muscles of the soft palate important for

A

speech and swallowing

31
Q

innervation of all soft palate muscles except tensor veli palatini

A

pharyngeal plexus of vagus nerve CN X

32
Q

tensor veli palatini is innervated by

A

mandibular nerve of trigeminal nerve cnv3

33
Q

palatoglossus muscle is apart of what 2 muscle groups

A

muscles of the tongue and soft palate

34
Q

palatopharyngeus forms what

A

posterior faucial pillars

35
Q

palatopharyngeus OI

A

origin: soft palate
insertion: laryngopharynx and thyroid cartilage

36
Q

palatopharyngeus action

A

closes nasopharynx during swallowing

37
Q

uvula muscle is contained

A

completely within uvula

38
Q

what does the uvula muscle do

A

helps to seal palate

39
Q

uvula deviates

A

away from the vagus nerve lesion

40
Q

uvula:
tongue:

A

away

towards

41
Q

levator veli palatini OIA

A

origin: temporal bone
insertion: median palatine raphe
action: elevates soft palate to help close off oropharynx

42
Q

tensor veli palatini OIA

A

origin: auditory tube and sphenoid bone to tendon near pterygoid hamulus
insertion: tendon near pterygoid hamulus to median palatine raphe

action: tenses and slightly lowers soft palate

43
Q

tissue projection that hangs inferiorly from posterior soft palate in uvula

A

muscle of the uvula

44
Q

soft palate closely adapts to posterior pharyngeal wall to help close off nasopharynx

A

action of muscles of uvula
