Is the epiglottis attached to the thyroid?
The epiglottis attaches to thyroid cartilage by thyroepiglottic ligament and to hyoid bone by hyoepiglottic ligament. Quadrangular membrane is fibrous membrane that extends from upper arytenoid and corniculate cartilages to lateral epiglottis.
Is the larynx above the thyroid?
The thyroid cartilage is a hyaline cartilage structure that sits in front of the larynx and above the thyroid gland. The cartilage is composed of two halves, which meet in the middle at a peak called the laryngeal prominence, also called the Adam’s apple.

Where is the epiglottis attached to the thyroid bone?
The epiglottis is located in the larynx and attached to the thyroid cartilage and hyoid bone. Its movements are regulated by the passive pressure from the tongue as it pushes the food down the pharynx, as well as by the contractions of the aryepiglottic muscle.
What is the function of the epiglottis cartilage?
The epiglottis is a flap of elastic cartilage that sits beneath the tongue at the back of the throat. Its main function is to close over the windpipe (trachea) while you’re eating, to prevent food entering your airways. The epiglottis stalk attaches anteriorly to the internal aspect of the angle of the thyroid cartilage (Figure 1).
