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.
Test your knowledge of the structure and boundaries of the oral mucosa and oral cavity. Learn about the components and parts of the oral mucosa and how they relate to the anatomy of the oral cavity.
