Anatomy

The plica semilunaris of the fauces is situated at the posterior end of the oral cavity, near the entrance to the pharynx. It is a part of the palatoglossal arch, which is a fold of mucous membrane that extends from the soft palate to the side of the tongue. The plica semilunaris is located on the inner side of this arch.

Function

The primary function of the plica semilunaris of the fauces is to assist in the process of swallowing. It helps guide food and liquid from the mouth into the esophagus, preventing it from entering the nasal cavity or the larynx.

Clinical Significance

In some cases, the plica semilunaris of the fauces can become inflamed or infected, leading to a condition known as Faucitis. This can cause symptoms such as sore throat, difficulty swallowing, and fever. Treatment typically involves antibiotics and anti-inflammatory medications.
