Which one of the following parts of the pharynx is the continuation of the internal nares?
Options:
Answer:
Solution:
The nasal cavity extends posteriorly and opens into the pharynx through the internal nares.
The pharynx is anatomically divided into three regions: the nasopharynx, oropharynx, and laryngopharynx.
The nasopharynx is the superior portion of the pharynx, located immediately posterior to the nasal cavity. It serves as the direct continuation of the internal nares and acts as a passageway for air.
The oropharynx lies posterior to the oral cavity, and the laryngopharynx is the inferior part, located posterior to the larynx.
The epiglottis is a cartilaginous flap that covers the glottis during swallowing to prevent food from entering the trachea.
Therefore, the nasopharynx is the part of the pharynx that is the continuation of the internal nares.
Answer: Nasopharynx.
