Epiglottis
- In the adult, the epiglottis is a "leaf-shaped" cartilage that prevents liquids or foods from entering the respiratory tract. It is one of the major anatomical landmarks sought during endotracheal intubation.
Thyroid Cartilage
- The thyroid cartilage forms the majority of the anterior and lateral surface of the larynx. This anterior anatomical landmark is usually palpable and is commonly known as the "Adams Apple."
Cricoid Cartilage
- The cricoid cartilage sits beneath the thyroid cartilage providing posterior support to the larynx. Together the thyroid and cricoid cartilage provide structure and support to the glottis. [3]
