Aryepiglottic Muscle

Aryepiglottic muscle (labeled as aryepiglotticus) as seen from behind.

The Aryepiglottic Muscle is a small, triangular muscle in the larynx. It is part of the intrinsic muscles of the larynx, which control the position and tension of the vocal cords. The muscle originates from the arytenoid cartilage and inserts into the lateral border of the epiglottis.

Structure

The Aryepiglottic Muscle is a slender, band-like muscle that extends from the muscular process of the arytenoid cartilage to the lateral margin of the epiglottis. It is covered by the aryepiglottic fold, which is a fold of mucous membrane extending between the arytenoid cartilage and the epiglottis.

Function

The primary function of the Aryepiglottic Muscle is to assist in closing the laryngeal inlet during swallowing, preventing food and liquid from entering the trachea. It also helps to control the tension of the vocal cords during speech.

Clinical significance

Damage to the Aryepiglottic Muscle can result in difficulty swallowing (dysphagia) and changes in voice quality. It may also contribute to conditions such as laryngospasm and laryngeal stenosis.
