What is aryepiglottic fold?

The aryepiglottic fold is a structure located in the larynx, specifically between the arytenoid cartilage and the epiglottis. It plays a role in protecting the airway during swallowing by helping to close off the entrance to the larynx.

The aryepiglottic fold is made up of mucous membrane and connective tissue, and it is covered by ciliated epithelium to help trap and remove foreign particles from entering the airway. It also contains lymphoid tissue that can help protect against infections.

During swallowing, the aryepiglottic fold moves inward to help close the entrance to the larynx, preventing food or liquid from entering the airway and potentially causing choking. It is an important part of the body's swallowing mechanism and contributes to the overall function of the larynx in speech and respiration.
