Explanation:
Detailed explanation-1: -Oral mucosa (mucous membranes): The oral mucosa is a lining all over the inside of your mouth.
Detailed explanation-2: -The oral vestibule is bounded externally by the lips and the cheek mucosa and internally by the alveolar processes and the teeth. When the teeth are in occlusion, the vestibule communicates with the oral cavity proper via the intermaxillary commissure behind the last molar teeth.
