What are the opening of the oropharynx?
The oropharynx lies behind the oral cavity, extending from the uvula to the level of the hyoid bone. It opens anteriorly, through the isthmus faucium, into the mouth, while in its lateral wall, between the palatoglossal arch and the palatopharyngeal arch, is the palatine tonsil.
Are larynx and laryngopharynx the same?
The laryngopharynx, also referred to as the hypopharynx, is the most caudal portion of the pharynx and is a crucial connection point through which food, water, and air pass.

What anatomy is in the oropharynx?
The oropharynx includes the soft palate, tonsils, base of the tongue, and pharyngeal walls bounded superiorly by the nasopharynx and inferiorly by the pharyngoepiglottic fold. It extends from the level of the soft palate superiorly to the level of the hyoid bone inferiorly.
What separates nasopharynx and oropharynx?
