1

What is the space between the vocal folds called?

glottis

2

What is the space above the vocal folds, below the base of the tongue called?

supraglottal area

3

What is the space below the true vocal folds called?

Infraglottal area

4

What is the aditus?

the opening of the larynx

5

What is the space between the false folds & the aditus called?

Laryngeal vestibule

6

What are the 3 layers of the VF?

1. Cover- includes the superficial layer of the lamina propria
2. Transition- intermediate & deep layer of the lamina propria
3. body- thyroarytenoid muscle

7

Which nerve serves the larynx?

CN X- vagus

8

What is the vital capacity?

the amount of air available for use when lungs are inflated maximally

9

What is the Bernoulli effect?

occurs when a flow of air meets a constriction. This results in an increase in the airflow rate through the constriction balanced by an air pressure decrease at the point of constriction. This decrease in air pressure creates a suction effect & pulls the VF back towards one another

10

When does vibration of the VF occur?

the VF are in the adducted position & airflow from the lungs causes repeated opening & closing- results in voicing

11

What is phonation?

the degree of VF opening during speech production

12

What is fundamental frequency?

the number of time per second the VF open & close during voicing

13

Frequency is the inverse of what measure?

period

14

What determines fundamental frequency?

vocal fold mass & stiffness

15

What is jitter?

the varying in frequency (pitch) from one cycle to the next

16

what is shimmer?

the varying in amplitude (intensity) from one cycle to the next

17

What is maximum phonation time?

the maximum time a subject can produce a vowel following deep inhalation
