The plica semilunaris of the fauces is a fold of mucous membrane located in the oropharynx, which is part of the pharynx. It is situated near the palatine tonsils and plays a role in the process of swallowing.

Anatomy

The plica semilunaris of the fauces is found in the lateral wall of the oropharynx. It is a crescent-shaped fold that is positioned between the palatoglossal arch and the palatopharyngeal arch. These arches are formed by the underlying muscles, the palatoglossus and palatopharyngeus, respectively.

Function

The primary function of the plica semilunaris of the fauces is to aid in the movement of food from the mouth to the esophagus during swallowing. It helps guide the bolus of food and prevents it from entering the nasopharynx.

Clinical significance

Inflammation or infection of the plica semilunaris of the fauces can occur in conditions such as pharyngitis or tonsillitis. This can lead to symptoms such as sore throat, difficulty swallowing, and swelling in the throat area.
