What is the oral cavity?
The oral cavity is the beginning of the aerodigestive tract. The oral cavity starts at the lips and ends where the mouth meets the throat. The oral cavity is made up of multiple parts including the lips, tongue, floor of mouth, gingiva, buccal mucosa, hard palate, and retromolar trigone.
What types of cells are normally found in the oral cavity?
The inner surface of the oral cavity is covered by specialized squamous cells. that form a barrier called the epithelium. The tissue below the epithelium is called the stroma. Pathologists use the word mucosa to describe tissue that includes both the epithelium and the stroma.
