A prepositional phrase is comprised of two parts, a preposition and an object of the preposition. Together, they form the prepositional phrase that is then inserted in a sentence to modify some noun or verb.
The epiglottis is a flap made of elastic cartilage tissue covered with a mucous membrane, attached to the entrance of the larynx. It projects obliquely upwards behind the tongue and the hyoid bone, pointing dorsally. It stands open during breathing, allowing air into the larynx.
The epiglottis is a structure found in the throat. Specifically, it's located behind the tongue and above the larynx. Elastic cartilage forms this thin, teardrop-shaped flap. A mucous membrane coats the epiglottis.The side facing the mouth is covered in cells similar to those in the rest of the mouth, whereas the backside is covered with cells resembling those of the larynx. The epiglottis is held in place by two ligaments.he esophagus delivers food to the lower digestive system whereas the larynx is the passageway for air to enter the lungs. To prevent food or drink from getting into the lungs, the epiglottis moves to cover the larynx when swallowing. This movement is accomplished by muscles reacting to contact with food or drink.
