ANasopharynx, oropharynx and epipharynx
BOropharynx, laryngopharynx and glottis
CNasopharynx, fauces and laryngopharynx
DNasopharynx, oropharynx and laryngopharynx
Answer & Solution
Correct answer: D. Nasopharynx, oropharynx and laryngopharynx
1. The pharynx is a muscular tube lined by mucous membrane continuous with that of the nasal cavities.
2. It divides into the nasopharynx, the oropharynx and the laryngopharynx.
3. So the fourth option lists all three correctly.
4. The fauces is only the opening between the oral cavity and the oropharynx, and the glottis belongs to the larynx, so neither is a pharyngeal region.
