What tissue is lining the oral cavity?
oral mucosa
The mucous membrane that lines the structures within the oral cavity limits is known as oral mucosa. This is a wet soft tissue membrane that extends from the junction between the vermilion border of the lips and labial mucosa anteriorly to the palatopharyngeal folds posteriorly.
What cavity is the immune system in?
The mucosal immune system is a localized and specific immune organization protecting nearly the whole inner surface of the human body, spanning the mucosal surfaces of the oral-pharyngeal cavity, gastrointestinal (GI) tract, respiratory tract and urogenital tract, as well as the exocrine glands.
What type of epithelium is in the mouth?
stratified squamous epithelium
The oral mucosal epithelium is a barrier that separates the underlying tissues from their environment. It consists of two layers, the surface stratified squamous epithelium and the deeper lamina propria.
What is lining epithelium of tongue?
The surface of the tongue is covered by stratified squamous epithelium, modified on the upper surface into filiform papillae. Taste buds are oval clusters of elongated cells which extend across the thickness of the epithelium, from the lamina propria to the taste pore at the surface.

Oral immune tolerance is the result either of lack of activation of T cells in response to immunogenic presentation of antigens or of suppression of activity of effector T cells by regulatory T cells.
What are parts of the immune system?
The main parts of the immune system are: white blood cells, antibodies, the complement system, the lymphatic system, the spleen, the thymus, and the bone marrow. These are the parts of your immune system that actively fight infection.

What is the epithelium of oral cavity?
The oral cavity is lined by a mucous membrane (the oral mucosa) consisting of a stratified squamous epithelium, which may or may not be keratinized, and an underlying connective tissue layer, the lamina propria.
What is mucosal epithelium?
A mucous membrane or mucosa is a membrane that lines various cavities in the body and covers the surface of internal organs. It consists of one or more layers of epithelial cells overlying a layer of loose connective tissue. Some mucous membranes secrete mucus, a thick protective fluid.
What are parts of the oral cavity?
The oral cavity includes the lips, hard palate (the bony front portion of the roof of the mouth), soft palate (the muscular back portion of the roof of the mouth), retromolar trigone (the area behind the wisdom teeth), front two-thirds of the tongue, gingiva (gums), buccal mucosa (the inner lining of the lips and …
