Which body cavity contains the teeth and tongue?

Which body cavity contains the teeth and tongue?

• A. Nasal cavity
• B. Oral cavity
• C. Orbital cavities
• D. Middle ear cavities

Answer: (B)

The space that holds the mouth’s structures is the oral cavity. Teeth are set in the upper and lower jaws within the alveolar ridges, and the tongue sits on the floor of the mouth inside this cavity. The oral cavity is separated from the nasal cavity above by the palate and opens posteriorly into the oropharynx. The other options don’t contain both teeth and tongue: the nasal cavity is the air passage behind the nose; the orbital cavities are the eye sockets; the middle ear cavities house the tiny auditory bones. So the oral cavity is the only place that houses both teeth and tongue.
