Voice

Question 1

Laryngeal Valve (Larynx)

Answer 1

Several Sections:
Aryepiglottic Folds
Ventricular Folds(False vocal folds)
Ventricles
True Vocal Folds

Question 2

Aryepiglottic Folds

Answer 2

anterior epigolttic folds- top of the larynx

1st line of defense for preserving airway

Question 3

Ventricular folds

Answer 3

False vocal folds
2nd sphincter not active during phonation
form “double layer” medial closure
Primary Fcn: increase intrathoracic pressure by blocking the outflow of air to the lungs.

Question 4

Ventricles

Answer 4

Pouch of space between the false vocal folds and the true vocal folds

Question 5

True Vocal Folds

Answer 5

open for breathing, close for airway protection, vibrate to produce sound

Question 6

Voice disorder

Answer 6

A persons quality, pitch, loudness

Question 7

Reason behind Voice disorder

Answer 7

structure or fcn of laryngeal mechanism no longer meet voiceing requirements

Question 8

Artistic Nature Voice Care

Answer 8

human interaction, empathy, listening skills: voice quality/what is said, counseling skill, motivational, Aura credibility

Question 9

Scientific Nature of Voice Care

Answer 9

anatomy/physiology
etiologic correlates
laryngeal pathologies
vocal acoustics
vocal aerodynamics
EBP therapy methods

Question 10

3 subsystems of Voice

Answer 10

respiration
phonation
resonance

Question 11

Larynx basic fcn

Answer 11

airway protection, airway preservation (ventilation), Phonation

Question 12

3 Levels of Laryngeal folds

Answer 12

aryepiglottic folds
Ventricular (false) Folds
True Folds

Question 13

Aryepiglottic folds

Answer 13

connects to lower epiglottic tissue

first line of defense in preserving airway

Question 14

Ventricular folds

Answer 14

false vocal folds
superior to ventricles and true vocal folds
not normally active during phonation except maybe effertful activity
fcn: inc intrathoracic pressure

Question 15

True Vocal Folds

Answer 15

open for breathing, close for airway protection, vibrate to produce sound, closure angles multidimensional (horizontal, vertical, etc.)

Question 16

Phonation power source

Answer 16

relies on pulmonary respiratiory power

Question 17

Diaghragm

Answer 17

primary muscle of quiet inspiration

Question 18

Pleural lining

Answer 18

double walled

Question 19

Resonance

Answer 19

occurs when sound is reinforced or prolonged as acoustic waveforms reflect off another structure

Question 20

Fan’ts acoustic Theory

Answer 20

glottal sound source + supraglottic contributions+ resonant characteristics

Question 21

Laryngeal cartilages

Answer 21

9
epiglottis
thyroid
cricoid
3 paired-(arytenoids, corniculates, cuneiforms)

Question 22

Cricoid cartilage

Answer 22

ring with thicker back

articulate w/ throid and arytenoid cartilages

Question 23

Hyoid Bone

Answer 23

Horseshoe
superior border laryngeal complex
chronic elevation=tension laryngeal muscular sling(support)
connects to thyroid cartilage via throhyro membrane

Question 24

Epiglottis

Answer 24

cartilage
leaf
no direct role phonation

Question 25

Thyroid

Answer 25

saddle shape
Adams Apple-thyroid notch, prominence
lateral walls-plates-laminae

Question 26

3 paired cartilages

Answer 26

(ascending order)
arytenoids
corniculates
cuneiforms

Question 27

arytenoids

Answer 27

pyramid shaped
cartilaginous portions of the vocal folds
posterior points of attachement to vocal folds

Question 28

Adduction

Answer 28

close

Question 29

Abduction

Answer 29

open

Question 30

Corniculates

Answer 30

cartilage of santorini

Question 31

Cuneiforms

Answer 31

cartilages of wrisberg
