Ans.

💡Classification of Oral Mucous Membrane

The oral mucosa lines the inside of the oral cavity and is classified into three main types based on function and structure:

1. Masticatory Mucosa: Found in areas subject to friction and pressure during chewing, such as the gingiva and hard palate. It is keratinized, providing a tough, protective surface.

• • Location: Gingiva and hard palate.

  • Characteristic: Keratinized or parakeratinized epithelium.

  • Function: Withstands mechanical stress during chewing.

2. Lining Mucosa: This type covers the inner surfaces of the lips, cheeks, floor of the mouth, underside of the tongue, soft palate, and alveolar mucosa. It is non-keratinized, providing flexibility and allowing for movement.
