What is the location of the supraglottal cavity?

The supraglottal cavity is indeed located above the vocal folds, extending to the aryepiglottic folds. This anatomical region is significant in the study of speech and phonation because it includes the area where sound production begins as air passes through the vocal folds. In this cavity, various structures, including the epiglottis and the aryepiglottic folds, play essential roles in protecting the airway during swallowing and assisting in the modulation of sounds during speech.

Understanding the location of the supraglottal cavity is crucial for grasping how resonance and articulation occur above the vocal folds, influencing the quality of the voice and speech sounds produced. This area acts as a filter and can affect the tonal quality and timbre of the sounds generated by the vocal folds, highlighting its importance in both anatomy and the functions of speech and hearing.
