Vocal Cords (Vocal Folds) & Vestibular Folds of the Larynx
Glottis – Structure & Function
Last update:
The glottis is the area between the vocal cords, which connect the airways in your throat to your lungs.
A mirror positioned 
above the larynx shows a superior view of the vestibular and vocal folds.
Superior view of vestibular and vocal folds.
- The vocal folds and the space between the folds are referred to as the glottis (= glottic opening).

Laryngeal muscles can adjust the size of the glottic opening, depending on need.

- While breathing, The glottis
expands (= abducts) into a triangular shaped opening.
- The broader opening allows air to more freely enter and leave the trachea and lungs.
- To make voice sounds, the laryngeal muscles reduce (= adduct) the size of the glottic opening to a narrow slit.

There are two pairs of soft tissue folds projecting into the lumen of the larynx. The inferior folds are the vocal folds and the superior folds are the vestibular folds.
Thyroid and Cricoid Cartilages of the Larynx
The largest laryngeal cartilage is the thyroid cartilage. Inferior to the thyroid cartilage is the ring-shaped cricoid cartilage. Along with the epiglottis, they represent the large cartilages of the larynx.
The Epiglottis of the Larynx
The epiglottis projects obliquely from the top of the larynx. Muscles move the epiglottis to cover the larynx during swallowing to allow for the passage of food. As food clears the passageway, the muscles relax to reopen the respiratory passageway.
