What is the Aryepiglottic fold?

The aryepiglottic folds extend between the arytenoid cartilage and the lateral margin of the epiglottis on each side and constitute the lateral borders of the laryngeal inlet. They are involved in physiologic closure mechanisms of the larynx and in pathologic conditions such as inspiratory stridor.

What is voice fold?

Briefly, the vocal folds are folds of tissue located in the larynx (voicebox) that have three important functions: To protect the airway from choking on material in the throat. To regulate the flow of air into our lungs. The production of sounds used for speech.

What is larynx anatomy?

The larynx is a cartilaginous skeleton, some ligaments, and muscles that move and stabilize it and a mucous membrane. The laryngeal skeleton is nine cartilages: the thyroid cartilage, cricoid cartilage, epiglottis, arytenoid cartilages, corniculate cartilages, and cuneiform cartilages.

What Innervates aryepiglottic fold?

The aryepiglottic muscle is innervated by the inferior laryngeal nerve, a branch of the recurrent laryngeal nerve (a branch of the vagus nerve). The muscle adducts arytenoid cartilages and acts as a sphincter on the laryngeal inlet.

How does aryepiglottic fold bunching protect the airway?

During the movement of the larynx, the vocal folds and aryepiglottic folds adduct preventing material from entering the lower airway. Additionally, the epiglottis folds over the glottal space to act as another layer of protection from material entering the lower airway.

What are folds in the larynx?

The Cavity or Lumen of the Larynx In man there are three, the aryepiglottic folds, the vocal folds and the vestibular folds. The vocal folds divide the cavity of the larynx into supraglottic and infraglottic compartments separated by the glottis, the narrow gap between the vocal folds.

What are the folds in the larynx called?

There are two important soft tissue folds located within the larynx – the vestibular folds and vocal folds. They play a crucial role in protection of the airway, breathing, and phonation.

What is vocal fold paralysis?

Vocal fold paralysis (also known as vocal cord paralysis) is a voice disorder that occurs when one or both of the vocal folds don’t open or close properly. Single vocal fold paralysis is a common disorder. Paralysis of both vocal folds is rare and can be life threatening.

What is inside the vocal fold?

Vocal Cords and Vocal Folds ‘Vocal cord’ suggests a band or string suspended in the air that vibrates when it is plucked or struck. In fact, the vocal fold is a part of a muscle on the side of the larynx, covered with special tissues that can vibrate at a high speed. It resembles a lip of tissue much more than a cord.
