16
Q

vocal cord positioning

A

attached towards the front and open towards the back
forced respiration: will open wider
photonation: will tighten/move togther
whispering: posterior aspect with arytenoid cartilages will open as the cords come together

17
Q

inn of the cricothyroid

A

external laryngeal nn from CN X

18
Q

action of the cricothyroid

A

stretches and tenses vocal ligament, adjust tilt and geometry of the cords

19
Q

thryoarytenoid inn

A

inf laryngeal nn (part of the reccurent), CN X

20
Q

thryoarytenoid action

A

relax vocal ligament

21
Q

posterior cricoarytenoid action

A

opens the vocal fold (abducts)

22
Q

posterior cricoarytenoid inn

A

inf laryngeal nn (terminal branch of recurrent), CN X

23
Q

lateral cricoarytenoid inn

A

inf laryngeal nn (terminal branch of recurrent), CN X

24
Q

lateral cricoarytenoid action

A

adducts vocal folds

25
Q

transverse and oblique arytenoids inn

A

inf laryngeal nn (terminal branch of recurrent), CN X

26
Q

transverse and oblique arytenoids action

A

adduct arytenoid cartilages

27
Q

vocalis inn

A

inf laryngeal nn (terminal branch of recurrent), CN X

28
Q

vocalis action

A

within the ligament, relax posterior ligament while maintaining anterior tension

29
Q

L recurrent laryngeal nn hook around?

A

aortic arch

30
Q

R recurrent laryngeal nn wraps around?

A

subclavian Aa

31
Q

what nn can easily be damaged in neck surgery, result

A

recurrent laryngeal nn, can lead to loss of inn of the small laryngeal mm

32
Q

swallowing action effect on epiglottis

A

will cause entire larynx to rise up and allow epiglottis to cover opening and prevent airway obstruction/ promote food down esphogus

33
Q

piriform recess

A

spaces lateral to the vocal cords

34
Q

palatoglossal/pharygeal arches

possess mm of the same names

between them is the palatine tonsil

35

nn of the jugular foramen

A

CN 9,10,11

36
Q

muscles of the pharynx

A

sup, mid, and inf constrictors
stylopharyngeus
palatopharyngeus
salpinopharyngeus

37
Q

inn of the pharyngeal mm

A

All inn by CN X, except the stylopharyngeus=CN IX

38
Q

lymph drainage pattern

A

in/down towards the internal jugular

39
Q

thryoglossal duct cyst

A

due to improper migration of thyroid tissue from the foramen cecum
