What is the function and purpose of Hyolaryngeal elevation?
It moves the epiglottis up and closer to the base of the tongue and helps to fold the epiglottis down.

At rest it's upright so we can breathe.
During swallowing is when it curves for swallow.
The height of the swallow is when the inversion inverts to protect the airway.
