Exam 3

When phonation stops, the posterior cricoarytenoid muscle abducts

• True

• False

When the thyroarytenoid muscle moves from anterior to posterior position creating mucosal waves during sustained phonation, the posterior cricoarytenoid muscle abducts to create the mucosal wave

• True

• False

During whisper, the cartilaginous part of the vocal folds is closed.

• True

• False

Cricoarytenoid muscles increase the mass of VFs

• True

• False

The interaction of subglottal pressure, tissue elasticity and constriction within the airflow caused by the vocal folds, produces sustained phonation as long as pressure, flow and vocal fold approximation are maintained.    

• True

• False

Sustained phonation is due to neuronal stimulated contractions and adducting and abducting of the posterior cricoarytenoid muscle and the adductors

• True

• False

The interaction of subglottal pressure, tissue elasticity and constriction within the airflow caused by the vocal folds, produces sustained phonation as long as pressure, flow and vocal fold approximation are maintained.

• True

• False

Sound is caused by small areas of high and low pressure traveling outward from the source.

• True

• False

The largest vertebrae are

• lumbar

• throacic

• intravertebral cartilage

• cervical

Changes in FO will cause changes in

• breathiness

• pitch

• intensity

• amplitude
