Question 1

During the oral phase of swallowing, which action propels the bolus posteriorly toward the pharynx?

Accepted Answer

Posterior tongue movement pressing bolus against hard palate

Answer

During the oral phase, the tongue tip anchors anteriorly while the dorsum elevates and moves posteriorly, propelling the bolus toward the pharynx.

Question 2

What is the primary respiratory pattern change that occurs when switching from quiet breathing to conversational speech?

Accepted Answer

Expiratory phase is prolonged and controlled to sustain voicing

Answer

During speech, the expiratory phase is prolonged and carefully controlled through active muscle activity to sustain sufficient subglottal pressure for voicing.

Question 3

Which intrinsic tongue muscle changes the shape of the tongue from flat to grooved, which is critical for many speech sounds?

Accepted Answer

Transverse

Answer

The transverse muscle runs mediolaterally and narrows/elongates the tongue, contributing to grooving which is critical for fricative and other sounds.

Question 4

The Bernoulli effect during vocal fold vibration contributes to which phase of the vibratory cycle?

Accepted Answer

Closing of the vocal folds as airflow speeds up

Answer

As air accelerates through the narrowing glottis, the Bernoulli effect creates a drop in pressure that draws the vocal folds back toward midline, assisting closure.

Question 5

Which structure acts as the primary resonator responsible for voice quality differences between speakers producing the same fundamental frequency?

Accepted Answer

Vocal tract (pharynx, oral, and nasal cavities combined)

Answer

The vocal tract, encompassing the pharynx, oral, and nasal cavities, acts as an acoustic filter that shapes the spectral characteristics of the laryngeal source, producing unique voice quality.
