  • Forming the larynx are nine (9) supportive cartilages, several intrinsic and extrinsic muscles, and a mucous membrane lining.
  • As a primary function, the larynx provides a carefully guarded air passageway (See the GIF below)  between the pharynx and the trachea.

  • During the swallowing process, movements of the cartilages close the entrance to the larynx so food and drink cannot enter.
  • The larynx also houses the vocal folds and ligaments that produce the voice sounds.

Vocal Cords (Vocal Folds) & Vestibular Folds of the Larynx

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.
