The arytenoid cartilages are a pair of small, pyramid-shaped structures located in the larynx, or voice box. They play a crucial role in the production of sound by controlling the tension and position of the vocal cords. Each arytenoid cartilage is connected to the vocal cords and can pivot and slide, allowing for adjustments in pitch and volume during speech. These cartilages are essential for various functions, including breathing and swallowing. The arytenoids also serve as attachment points for several muscles that help open and close the vocal folds, contributing to the overall mechanics of phonation and respiration.
