What is the role of the arytenoids in the larynx?

• A. They produce sound
• B. They support the vocal cords
• C. They aid in swallowing
• D. They connect to the esophagus

Answer: (B)

The arytenoids are a pair of small cartilage structures located in the larynx, which plays a crucial role in the production of sound and the support of the vocal cords, also known as vocal folds. Their primary function is to serve as the attachment points for the vocal cords. When the arytenoid cartilages move, they change the tension and position of the vocal cords, significantly affecting pitch and volume during phonation. This mobility is essential for sound production as it allows the vocal cords to open and close efficiently, enabling a range of sounds. Although the arytenoids do play roles in sound production and indirectly in swallowing by helping to close the airway during the act of swallowing, their main function is to support and facilitate the functioning of the vocal cords. Thus, this understanding is critical when examining the anatomical relationships and physiological roles of structures within the larynx.
