Q

transverse arytenoid
oblique arytenoid

A

adduct arytenoids and vocal folds

17
Q

cricothyroid and cricoarytenoid muscles

A

glide, tilt, twist larynx

18
Q

lateral cricoarytenoid muscle

A

adduction by rocking arytenoids

19
Q

voiced sounds

A

vibration of vocal folds
abduction

20
Q

voiceless sounds

A

produced by mouth/throat
adduction

21
Q

production of glottal stop

A

vfs closed and suddenly open

22
Q

body cover model

A

how the vocal fold structure help frequencies, amplitudes and qualities of human vocal chords

23
Q

aerodynamic myoelastic theory of phonation

A

phonation is passive process controlled by air pressure and airflow
mechanical factors in muscular activity

24
Q

Bernoulli effect

A

pressure in a fluid decreases as velocity increases

25
Q

bernoulli effect during voicing

A

airflow increases when vocal folds blow open causing a drop in pressures perpendicular to the airflow

26
Q

what happens when the pressure drops in the bernoulli effect?

A

vocal folds snap

27
Q

fundamental frequency

A

number of times the vfs blow open and come together per second

28
Q

MEN fundamental frequency

29
Q

WOMEN fundamental frequency

30
Q

CHILDREN fundamental frequency

31
Q

spastic dysphonia

A

spasms that interfere with vocal fold vibrations
