Explanation:

Question 115

To solve this, we recall the anatomy of laryngeal cartilages. The epiglottis is a small, leaf - shaped cartilage located behind the tongue and hyoid bone. The cricoid cartilage is a ring - shaped cartilage, the thyroid cartilage is the Adam's apple - like structure, and the corniculate cartilages are small, horn - shaped cartilages. So the correct answer is the epiglottis.

Among the paranasal sinuses, the maxillary sinus is the largest. The frontal sinus is in the forehead area, the ethmoid sinus is composed of multiple small air cells, and the sphenoid sinus is located behind the ethmoid sinus. So we identify the maxillary sinus as the largest.

The olfactory epithelium is responsible for the sense of smell and is found covering the superior turbinate (and also the superior part of the nasal cavity). It is not lining the nasopharynx (the nasopharynx is lined by respiratory epithelium) and not lining the paranasal sinuses (paranasal sinuses are lined by respiratory epithelium too). So the correct location is covering the superior turbinate.

Answer:

D. epiglottis
