Answer to Question 1

ANS: A
The laryngeal component of speech is called phonation. It requires the adjustment of vocal cord tension and position relative to one another. The action of the posterior cricoarytenoid muscles causes the arytenoid cartilages to rotate and opens the vocal cords. Closure of the vocal cords is carried out by rotating the arytenoids in the opposite direction through the action of the lateral cricoarytenoid and oblique arytenoid muscles.

Answer to Question 2

ANS: D
Tight closure of the larynx and the buildup of intrapulmonary pressure through muscular effort is called effort closure. Effort closure of the larynx is necessary for generating loud sounds and for effective coughing and sneezing.
