The oropharynx includes the base of the tongue back 13 the soft palate at the back of the roof of the mouth the tonsils and the back of the throat. The oropharynx has a stratified squamous epithelium. Vertical plane defined by the circumvallate papillae anterior tonsillar pillars and border of hard and soft palate.

24 the anterior margin of the oropharynx is formed by a plane that joins the posterior border of the soft palate the anterior tonsillar pillars and the circumvallate papillae.
