The true vocal fold, also known as the vocal cords, are located within the larynx and play a crucial role in producing sound during speech. However, they can also refer to the vocal ligament, vocal membrane, or vocalis muscle. These terms are often used interchangeably, but each one refers to a specific part of the vocal fold. Additionally, the true vocal fold can also be referred to as the glottis or sound-producing apparatus. Regardless of the terminology used, the true vocal fold is essential for clear communication and expression and can be affected by various medical conditions, such as nodules or polyps, which can impact overall vocal quality.
