NEET PG DENTAL EXAM

Detailed explanation-1: -The nasopharynx represents the most superior portion of the pharynx, bounded superiorly by the skull base and inferiorly by the soft palate. The nasopharynx connects the nasal cavity to the oropharynx and contains the Eustachian tube openings and adenoids.

Detailed explanation-2: -Your nasopharynx is located toward the bottom and back of your skull. It’s in the back of your nose and the roof of your mouth. The top of your nasopharynx connects to your nasal cavity. The bottom connects to your oropharynx (middle throat), leading to your hypopharynx (lower throat), trachea and eventually lungs.

Detailed explanation-3: -Where are the eustachian tubes located? Your eustachian tubes extend from your middle ear to the upper part of your throat, just behind your nose.

Detailed explanation-4: -The intrapharyngeal opening is closed during swallowing to isolate the nasopharynx and nasal cavity from the oropharynx and laryngopharynx and prevent reflux of food and fluid into the nasal cavity.
