Study Notes
Characteristics of Oral Mucosa
- The connective tissue of the oral mucosa is made up of lamina propria.
- The oral cavity is bounded superiorly by the hard palate.
- A key difference between oral mucosa and skin is that oral mucosa is constantly moist, whereas skin is dry.
Boundary of Oral Cavity
- The oral cavity is bounded anteriorly and laterally by lips and cheeks.
- The oral cavity is bounded posteriorly by the pillars of fauces and tonsils.
Functions of Oral Mucosa
- The oral mucosa serves to protect deeper tissues and organs in the oral cavity from environmental factors and microorganisms.
- The oral mucosa protects deeper tissues and organs by separating them from environmental factors and microorganisms.
Saliva
- Saliva is the major secretion associated with the oral mucosa.
- Saliva plays a crucial role in protecting deeper tissues and organs in the oral cavity.
Comparative Characteristics
- A characteristic of oral mucosa compared to skin is that it is constantly moist, whereas skin is dry.
- Oral mucosa is more permeable and has a thinner epithelium compared to skin.
