Study Notes
Oral Mucosa
- The oral mucosa lines the oral cavity
- It's a mucous membrane, which is a type of tissue that lines the body's cavities
- There are three main types of oral mucosa: lining mucosa, masticatory mucosa, and specialised mucosa
- The lining mucosa covers the inside of the cheeks, lips, floor of the mouth, and ventral surface of the tongue.
- It is non-keratinised, which means it lacks a tough outer layer of keratin
- It is softer, moister, and more stretchable than the masticatory mucosa.
- The masticatory mucosa covers the gingiva and hard palate.
- It is keratinized, which means it has a tough outer layer of keratin.
- It is harder, firmer, and less stretchable than the lining mucosa.
- The specialised mucosa covers the dorsal surface of the tongue and contains taste buds.
- It is keratinized, but the keratin layer is thinner than that of the masticatory mucosa.
- Hyperkeratinisation is an increase in the thickness of the keratin layer.
- Hyperkeratinisation occurs when the lining mucosa is subjected to friction or trauma and appears as a white or gray patch.
- Oral pigmentation refers to the presence of dark spots in the oral mucosa.
- These spots can be caused by a variety of factors, including aging, smoking, and certain medications.
