The true vocal folds, also known as vocal cords, refer to a pair of flexible, muscular tissues located within the larynx, more specifically in the lower part called the glottis. They play a crucial role in producing sound during speech, singing, and other vocal activities.
The true vocal folds are positioned side by side, stretching horizontally across the larynx. These folds consist of layers of special tissue that vibrate when air passes through them, generating sound waves. When we speak, the muscles surrounding the vocal folds contract and adjust the tension, length, and thickness of these folds, controlling the pitch, volume, and quality of our voice.
Importantly, the true vocal folds are different from the false vocal folds, which are located above them. The false vocal folds are primarily involved in protecting the airway during swallowing or coughing, but do not directly participate in sound production.
Any abnormalities or disorders affecting the true vocal folds can result in voice changes or difficulties, such as hoarseness, voice fatigue, or voice loss. Common conditions include vocal nodules, polyps, or inflammation of the folds, which may require medical intervention or voice therapy. Surgery or other interventions may sometimes be necessary to treat severe vocal fold issues and restore vocal function.
Overall, the true vocal folds are vital anatomical structures responsible for voice production, enabling humans to communicate effectively through speech and singing.
