1

The ____________________adduct the vocal processes and membranous vocal folds, while the ______________________adduct the cartilaginous or posterior glottis

lateral cricoarytenoids ; interarytenoids

2

The cricothyroid muscle is responsible for increases in frequency and is innervated by the recurrent laryngeal nerve

False

3

When the thyroarytenoid muscles contract they

shorten the vocal folds, increase medial compression by bulking the vocal folds, can increase or decrease frequency

4

Changes in the composition of the___________can result in a decreased mucosal wave

superficial lamina propria

5

The deep layer of the laminia propria is composed of mainly elastin fibers and interstitial fluids.

False

6

The basement membrane zone is responsible for attachment of the _________to the ____________.

epithelium; superficial lamina propria

7

The superior laryngeal nerve is a branch of cranial nerve ___and provides motor innervation to _______and carries sensory information from the ______________________.

CN X ; the cricothyroid ; supraglottic area

8

The geniohyoid and mylohyoid muscles are ____________ and function to ______ the hyoid and larynx

suprahyoid muscles ; elevate

9

The recurrent laryngeal nerve innervates _________. Injury to the recurrent laryngeal nerve is more common on the ______side

all laryngeal muscles except cricothyroid ; left

10

The _________ and _________ muscles have their insertions on the _________ of the ________ cartilage

posterior cricoarytenoid and lateral cricoarytenoid ; muscular processes ; arytenoid

11

Elastic recoil plays an important role in vocal fold closure during vibration

True

12

The aerodynamic force that is responsible for opening the vocal folds is _______, while the aerodynamic force which helps to close the vocal folds is __________ that results from the __________

subglottal pressure ; negative pressure ; Bernoulli Effect

13

The Body - Cover Model of Frequency Control states that during high intensity phonation contraction of the TA muscle

will increase pitch as long as the cricothyroid muscle is not at maximum activity

14

Fundamental frequency of vocal fold vibration depends on

vocal fold length, mass, and elasticity

15

The convergent glottal shape occurs when the vocal folds are _____ and the net tissue velocity (i.e. movement) is ________.

opening; outward

16

In the One Mass Model (Vocal Tract Inertance) of vocal fold vibration, sustained phonation is driven by

alternating positive and negative supraglottic and transglottic (intraglottic) pressures

17

A vocal register is

a series of pitches perceived to be of the same timbre or quality, a series of pitches produced in the same physiological manner

18

Vocal quality (i.e. roughness, breathiness etc.) is determined by

degree of glottic closure and periodicity of VF vibration

19

The mucosal wave is an apparent sliding motion of the vocal fold cover over the vocal fold body.

True

20

In order to produce high vocal intensity (loud phonation)

the vocal folds must adduct completely, the closed phase of vibration must be longer than the open phase, respiratory drive must be adequate and subglottal pressure relatively high, the vocal folds must close rapidly

21

Intrinsic laryngeal muscle tension may be observed during endoscopic exam as

anterior - posterior compression, medial-lateral compression, and supraglottic compression or sphinctering

22

Puberphonia is a ________ disorder and is characterized by _______ phonation.

Functional; high pitch

23

Paradoxical VF Movement occurs when

the VFs ADduct during inhalation

24

Essential Tremor is a/an

Neurological disorder

25

ABductor spasmodic dysphonia is characterized by

breathiness and difficulty transitioning from voiceless stops to vowels

26

Bilateral VF adductor paralysis results in

the inability to adduct or close the VFs, risks to airway safety during swallowing

27

The cause/s of VF granulomas is/are

Intubation injury, acid reflux, vocal abuse/misuse
MALES

28

Sulcus vocalis

is a longitudinal groove along the entire medial VF edge, may be due to a ruptured cyst or may be congenital

29

Laryngomalacia

results in soft, floppy laryngeal cartilages that collapse into the airway
usually resolves with maturity
is characterized by inspiratory stridor

30

Reinke’s edema is

Very often related to smoking
