Superior vocal cord, also known as the false vocal cord or vestibular fold, refers to a pair of thick, fold-like structures located above the true vocal cords in the larynx. These two folds are situated within the laryngeal ventricle, which is the space between the true and false vocal cords.
Unlike the true vocal cords, the primary role of the superior vocal cords is not vocalization. Instead, they function to protect the true vocal cords and aid in various physiological processes. The superior vocal cords act as a protective mechanism by closing together tightly during swallowing, coughing, and other activities that require the airway to be closed off, preventing substances from entering the lower respiratory tract.
While the true vocal cords are responsible for producing sound during speech and singing, the superior vocal cords may produce minor sound variations. This is mainly due to the airflow passing over their surfaces.
The superior vocal cords are composed of thick and flexible tissue, which allows them to be elevated and lowered. Their ability to move contributes to the production of different vocal sounds and helps regulate airflow during breathing.
In certain cases, abnormalities or dysfunctions of the superior vocal cords can occur, leading to voice disorders or issues with swallowing. When these problems arise, medical intervention may be necessary to restore normal vocal cord function and alleviate associated symptoms.
