🔍 Ligaments

Add the epiglottis and note the hyo-epiglottic ligament that attaches the epiglottis to the hyoid bone.

	What is the function of the epiglottis?
It covers the airway during swallowing to avoid aspiration of food and/or saliva:

There are three areas of the larynx:

The laryngeal cavity above the vestibular ligaments forms the vestibule.
The middle cavity is the very thin area between the vestibular ligments and the vocal ligaments.
The infraglottic space is below the vocal ligaments to where the trachea begins.

Using the Draw tool and the 3D rendering, identify these areas.
