<P> The oropharynx lies behind the oral cavity , extending from the uvula to the level of the hyoid bone . It opens anteriorly , through the isthmus faucium , into the mouth , while in its lateral wall , between the palatoglossal arch and the palatopharyngeal arch , is the palatine tonsil . The anterior wall consists of the base of the tongue and the epiglottic vallecula ; the lateral wall is made up of the tonsil , tonsillar fossa , and tonsillar ( faucial ) pillars ; the superior wall consists of the inferior surface of the soft palate and the uvula . Because both food and air pass through the pharynx , a flap of connective tissue called the epiglottis closes over the glottis when food is swallowed to prevent aspiration . The oropharynx is lined by non-keratinised squamous stratified epithelium . </P>
