GENERAL HISTOLOGY

Detailed explanation-1: -The oral vestibule is a small slit-like space between the teeth and inner mucosal lining of the lips and cheeks. The mucosa of the lips and cheeks continues onto the gingiva to form the superior and inferior boundaries of the vestibule.

Detailed explanation-2: -The vestibule – the space between the soft tissue (lips and cheeks), and the teeth and gums. The vestibule is kept moist by secretions from the parotid salivary glands, which are located in front of the ears and behind the angle of the jaw.

Detailed explanation-3: -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.

Detailed explanation-4: -The oral mucosa are the tissues that line the interior of your mouth, while the salivary glands produce saliva. The bottom of your mouth, located under your tongue, is called the floor.

Detailed explanation-5: -Nonkeratinized squamous epithelium covers the soft palate, inner lips, inner cheeks, the floor of the mouth, and ventral surface of the tongue.
