Edition
1. Where does the oral cavity begin and end?: Begins and the lips and cheeks and ends at
the oral pharynx
2. What to systems do the oral cavity introduce?: Beginning of the digestive
system At the posterior forms a common pathway with the respiratory system
3. Where do the tonsillar pillars lie?: Between the anterior and posterior tonsillar pillars
4. The oral cavity is divided into two parts:: vestibule and oral cavity proper
5. Vestibule: Space between the teeth and the inner mucosal lining of the lips and cheeks
6. Where does an edentulous person's vestibule end?: At the alveolar ridge
