Which structures are considered part of the oral cavity?

• A. Lips, Cheeks, Hard and Soft Palates, Tongue, Teeth, Gingiva, Salivary Glands
• B. Nasal Conchae
• C. Larynx and Trachea
• D. Esophagus and Stomach

Answer: (A)

Structures that form and line the oral cavity include lips, cheeks, hard and soft palates, tongue, teeth, gingiva, and salivary glands. These components define the mouth itself and host the main activities of eating, tasting, and saliva production. The other items listed don’t belong to the oral cavity: nasal conchae are part of the nasal cavity; the larynx and trachea belong to the airway; and the esophagus and stomach are downstream in the digestive tract, connected to the mouth but not part of its cavity.
