Detailed explanation-2: -The epiglottis is leaf-like elastic cartilage. Its narrow base is called the stalk (petiolus) and it is attached to the laryngeal prominence of the thyroid cartilage via an elastic ligamentous band called the thyroepiglottic ligament.

Detailed explanation-3: -The epiglottis is a leaf-shaped flap in the throat that prevents food and water from entering the trachea and the lungs.

Detailed explanation-4: -The epiglottis is a small, movable “lid” just above the larynx that prevents food and drink from entering the windpipe.
