Oropharynx

The Oropharynx is a part of the pharynx that is located in the human body. It is situated behind the oral cavity, extending from the uvula to the level of the hyoid bone. It opens anteriorly, through the fauces, into the mouth, while in its lateral wall, between the palatine tonsil and the epiglottis, is the palatopharyngeal arch.

Anatomy

The oropharynx is bordered superiorly by the nasopharynx and inferiorly by the laryngopharynx. The anterior wall consists of the base of the tongue and the epiglottic vallecula, the lateral walls are formed by the tonsils, and the posterior wall is formed by the pharyngeal wall.

Function

The main function of the oropharynx is to serve as a conduit for the passage of food from the mouth to the esophagus. It also plays a role in speech and breathing.

Clinical significance

Diseases of the oropharynx include oropharyngeal cancer, tonsillitis, and pharyngitis. These conditions can affect the function of the oropharynx and may require medical intervention.
