The vibrations consist of lateral and medial movements that produce the mucosal wave as the vibrations travel from lower to upper vocal folds. There is a slight time lag between the approximation and separation of lower and upper edges of vocal folds. This is called the vertical phase difference. The vocal folds close the glottis horizontally from anterior to posterior and posterior to anterior (similar to a zipper). The glottis closes in the opposite direction from anterior to posterior thus creating a time lag called the longitudinal phase difference. These movements contribute to that mucosal wave motion. Convergent and Divergent are terms used to describe the glottis shape during vibration. Convergent shape is used to describe when…
