The vocal ligaments are also known as the inferior thyroarytenoid. They are two thick ligament bands found inside the non-muscular portion of the throat’s vocal folds.
The ligaments are each made up of a band of yellowish elastin and collagen fibers. They are attached in front to the thyroid cartilage and at the back to the arytenoid’s vocal processes. These ligaments prevent excessive stress on the vocal cords by limiting the amount of elongation possible in the vocal fold; they also help keep the vocal fold in position or move it when the arytenoid cartilage moves during speech or other vocalizations.
