Definition

1. Noun:
   • A fold of mucous membrane in the larynx: The "vestibular fold" is one of two thick, pinkish folds of mucous membrane located above the true vocal cords in the larynx. They are not primarily used for sound production.
   • A non-vocalizing structure in the larynx: These folds are also known as the false vocal cords because, unlike the true vocal cords below them, they are not typically involved in creating the voice for speech.

Advanced Usage
