Laryngeal structures include which of the following that are elastic bands involved in sound production?

Phonation relies on the vibration of elastic bands within the larynx. The true vocal cords are two mucosal folds of dense, elastic tissue that come together and vibrate as air from the lungs passes through the glottis, producing sound. By adjusting their tension and length with the intrinsic laryngeal muscles, you change pitch and timbre—the cords become tighter and thinner for higher notes, or looser for lower ones. The other structures don’t serve as the main vibratory sound source: cartilaginous rings provide rigid airway support, vestibular folds (false vocal cords) protect the airway and assist swallowing rather than drive normal phonation, and cilia are tiny hairlike cells that move mucus and debris, not contribute to sound production.
