Which cartilage is recognized as the highest in the larynx?

The epiglottis is recognized as the highest cartilage in the larynx because it is located at the top of this structure and plays a crucial role in the respiratory system by preventing food and liquid from entering the trachea during swallowing. The epiglottis is a leaf-shaped flap of cartilage that is pliable and is anchored to the interior of the thyroid cartilage. Its positioning ensures it can fold down over the laryngeal opening to act as a barrier, facilitating safe passage of food into the esophagus.

In contrast, the thyroid cartilage, while significant as the largest cartilage in the larynx, is situated lower than the epiglottis. The cricoid cartilage forms a complete ring around the airway but is also located beneath both the thyroid and epiglottis. The arytenoid cartilages are paired structures positioned behind the thyroid and cricoid cartilages and are primarily involved in the movement of the vocal cords, making them lower in the laryngeal hierarchy. Therefore, the epiglottis stands out as the highest cartilage in the larynx.
