Aryepiglottic Muscle

The Aryepiglottic Muscle (pronunciation: ar-ye-ep-i-glot-tic mus-cle) is a small, triangular muscle located in the larynx. It is one of the intrinsic muscles of the larynx, which control the position and tension of the vocal cords.

Etymology

The term "Aryepiglottic" is derived from the Greek words "arytaenoides" meaning ladle-shaped, and "epiglottis" meaning upon the tongue.

Anatomy

The Aryepiglottic Muscle originates from the muscular process of the arytenoid cartilage and inserts into the lateral border of the epiglottis. It functions to close the laryngeal inlet by pulling the epiglottis towards the arytenoid cartilage, thus preventing food and liquid from entering the trachea during swallowing.

Related Terms

  • Arytenoid Cartilage: A pair of small three-sided pyramids which form part of the larynx, to which the vocal cords are attached.
  • Epiglottis: A leaf-shaped flap in the throat that prevents food and drink from entering the windpipe and the lungs.
  • Laryngeal Inlet: The opening that connects the pharynx and the larynx.
