What happens if there is no epiglottis?
If the epiglottis is absent in the body then the regulation of food material to esophagus and air into the lungs will get disturbed. Sometimes food will enter into the windpipe and then causes choking. Eventually, the lungs cannot not work properly which can lead to death.

What is the epiglottis?
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. The lateral margins of the epiglottis are connected with the arytenoid cartilages of the larynx via ...
Which bone pulls the stalk of the epiglottis in the same direction?
The hyoid bone, then, due to its attachment to the epiglottis via hyoepiglottic ligament, pulls the stalk of epiglottis in the same direction. This results in further moving of the free end of the epiglottis in the opposite direction, i.e. posteriorly towards the laryngeal inlet.
What is the inferior part of the epiglottis?
The inferior part of the lingual surface of the epiglottis lies posterior to the hyoid bone and thyrohyoid membrane. The space between this surface and the thyrohyoid membrane is called the pre-epiglottic space and it is filled with adipose tissue and lymphatics.
What is the lateral margin of the epiglottis?
The lateral margins of the epiglottis are connected with the arytenoid cartilages of the larynx via the aryepiglottic folds.
