Respiratory Function

Question 1

Biological role of the larynx:

Answer 1

breathing, swallowing, cough

Question 2

Crucial laryngeal role in breathing:
.. during quiet breathing (controlled by?)
maximum ? during?
adducting on expiration to increase ?

Answer 2

abduction / PCA
abduction/inspiration
laryngeal airway resistance (controlled by LCA, IA, and TA muscles)

Question 3

Task of respiratory system for voice: 
maintain ? 
-.. levels 
-... levels 
-appropriate ?

Answer 3

appropriate subglottal pressure for particular speech task

• vocal intensity levels
• fundamental frequency levels
• appropriate intonation control (intensity and frequency)

Question 4

How accomplished?

• speak on
• lung volume

recoil pressures help us?

plus we actively ? to maintain ?

Answer 4

expiration
decreases

generate the air pressures in the lungs for speech

balance forces (recoil +muscular) / appropriate Ps during speech utterance

Question 5

What are recoil forces:
the lung thorax unit is
when an elastic object is displaced from rest position?
the recoiling lung-thorax will ?

Answer 5

elastic object

it will recoil back to its rest position

affect the air pressure in the lungs

Question 6

Self-demonstration-end expiratory level (EEL) 
what is this ?
hold your breath at ?
this is called 
this is close to the ? 
this is about.... of your vital capacity

Answer 6

tidal volume (breathing at rest)

• end of resting expiration
• end-expiratory level
• rest position of lung-thorax unit
• 35%

Question 7

Recoil at lung volumes above EEL

The recoil force is creating ?

Answer 7

positive air pressure in your lungs without you actively contracting your muscles

Question 8

Recoil at lung volumes below EEL

The recoil force is creating ?

Answer 8

negative air pressure without yo actively contracting your muscles

Question 9

Voice and Respiratory Function:
Pressure
the subglottal pressure requirement for comfortable effort voice production is:

the pressure requirement increases for loud voice production =

and increases more for singing:

Answer 9

4-6cm H2o

8-10cm m H2O

20-25cm H2O

Question 10

airflow: flow is the volume of air passing through ? like flow through the?

airflow is the?

air is forced through ?
vocal folds for
articulators for

Answer 10

tube or duct per unit time
/ lower airways, glottis, and vocal tract

medium for propagation of sound

constrictions along the respiratory tract to generate sound/ voicing/ speech sounds

Question 11

The constriction: the vocal folds function as a ? to regulate ?

glottis ? slightly for ? and opens ? for ? which helps keep?

this regulation autonomically controlled by ?

Answer 11

valve/ airflow by offering a slight resistance to flow

closes / high lung pressures/ wider/ low lung pressures which helps keep pulmonary airflow more constant

nervous system

Question 12

Breathy voice: constriction is ?

pressed voice the constriction is ?

Answer 12

less as vocal folds more abducted

more as vocal folds are more adducted

Question 13

Modifying voice parameters with with pressure:

increases in F0 associated with increases in ?

increase in pressure = ?

Answer 13

subglottal pressure, glottal airflow rates, and elongation of vocal folds

increase in vibrational amplitude

Question 14

Sound pressure level:

increases in SPL associated with increases in ?

greater subglottal pressure =

Answer 14

subglottal pressure, medial compression, and increased F0

greater speed of VF closure which causes a greater proportion of the higher harmonics
