The elastic cartilage that shields the opening to the larynx during swallowing is the __________.
A
arytenoid cartilage
B
thyroid cartilage
C
cricoid cartilage
D
epiglottis
Verified step by step guidance1
Understand the function of the elastic cartilage in question: It shields the opening to the larynx during swallowing to prevent food or liquid from entering the respiratory tract.
Recall the anatomy of the larynx and its associated cartilages: The larynx contains several types of cartilage, including the arytenoid, thyroid, cricoid, and epiglottis, each with distinct roles.
Focus on the epiglottis: The epiglottis is a flap-like structure made of elastic cartilage that covers the laryngeal opening during swallowing, ensuring food is directed into the esophagus.
Differentiate the other cartilages: The arytenoid cartilage is involved in vocal cord movement, the thyroid cartilage forms the bulk of the larynx's structure (commonly known as the Adam's apple), and the cricoid cartilage provides support below the thyroid cartilage.
Conclude that the correct answer is the epiglottis, as it specifically performs the function described in the problem.
