Aryepiglottic fold

Aryepiglottic fold

The aryepiglottic fold (or simply the aryepiglottic fold) is an anatomical structure located on the posterior wall of the larynx. It is a fold of the mucous membrane that is located between the scoop and the epiglottis. This fold plays an important role in the formation of the vocal tract and allows air to pass through the larynx.

Anatomical structure of the aryepiglottic fold

The fold consists of two layers: internal (mucosal) and external (connective tissue). The mucous layer forms the surface of the fold, and the connective tissue layer provides its strength and stability.

The inner layer of the aryepiglottic fold contains glands that secrete mucus necessary to moisten the airways. On the surface of the mucous membrane there are also cilia, which ensure the movement of mucus towards the pharynx.

The outer layer of the aryepiglottic fold consists of elastic fibers that form the frame of the fold. This layer also contains blood vessels and nerves that provide nutrition and innervation to the fold.

Functions of the aryepiglottic fold
The aryepiglottic fold performs several functions:

  1. Vocal tract formation. The fold forms a channel through which air passes during voice formation. At the same time, it provides the necessary space for air to pass through, which allows you to create the sound of the voice.

  2. Protection against foreign bodies. aryepiglottic fold



The aryepiglottic folds are part of the larynx and are located between the epiglottis and the aryten, which are paired cartilages in the larynx.

The aryepiglottic folds are two soft tissues that form a fold on the back of the larynx and play an important role in the formation of the vocal cords.

When the aryepiglottic folds contract, they provide closure to the vocal cords and prevent air from entering the vocal cords during breathing.

If the aryepiglottic folds are abnormal, voice problems may occur, such as hoarseness or loss of voice. This can be caused by various factors such as diseases of the larynx, infections, trauma or surgery to the larynx.

If problems with the aryepiglottic folds are detected, it is recommended to consult a doctor for diagnosis and treatment.
