The true vocal cords are located in which part of the larynx?

The true vocal cords, also known as the vocal folds, are located in the glottis, which is the central part of the larynx. The glottis serves as the primary site for phonation, as it encompasses the true vocal folds and the space between them (the rima glottidis). When air passes through this area, it causes the vocal folds to vibrate, producing sound.

The subglottis is the area below the vocal cords, and it plays a role in air passage to the trachea but does not contain the vocal folds themselves. The supraglottis, which is above the vocal cords, includes structures such as the epiglottis and the false vocal cords (ventricular folds), also not involved in the actual production of sound. The epiglottis is primarily a protective structure that prevents food and liquid from entering the airway during swallowing and does not contain the true vocal cords.

Understanding the anatomy of the larynx and the specific locations of its components helps clarify the function of each part, particularly in the context of voice production in the glottis.
