Study Notes

Oral Mucosa Functions

  • The oral mucosa with nonkeratinized epithelium and thick lamina propria has a primary function of facilitating speech and swallowing.
  • The sulcus terminalis, a part of the oral mucosa, has a special masticatory function.
  • The oral mucosa found in areas exposed to compressive force, shear force, and abrasion is characterized by the presence of masticatory mucosa.
  • The oral mucosa with a smooth epithelial-CNT junction is characterized by the presence of lining mucosa.
  • The oral mucosa with more elastic fibers and fewer collagen fibers is classified as lining mucosa.
  • Masticatory mucosa, found in areas exposed to compressive force, shear force, and abrasion, has a primary function of withstanding these forces.
  • Lining mucosa is characterized by a smooth epithelial-CNT junction.
  • The oral mucosa with nonkeratinized epithelium and thick lamina propria has a primary function of facilitating speech and swallowing.
  • The sulcus terminalis, a part of the oral mucosa, has a special masticatory function.
