Answer to Question 1

ANS: C
During unconsciousness, the muscles of the tongue and hypopharynx can relax and allow the tongue and other soft tissues to collapse and occlude the opening of the hypopharynx. This con-dition can result in partial to complete blockage of the upper airway and limit air movement to and from the respiratory tract. This is a primary cause of obstructive sleep apnea.

Answer to Question 2

ANS: D
The pharynx is subdivided into the nasopharynx, oropharynx, and hypopharynx or laryngophar-ynx.
