IMMUNOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -These membranes are referred to as the oral mucosa, esophageal mucosa, gastric mucosa, and intestinal mucosa.

Detailed explanation-3: -The oral mucosa is the mucous membrane lining or “skin” inside of the mouth, including cheeks and lips. People with oral mucosal diseases may develop painful mouth sores or ulcers on this lining.

Detailed explanation-4: -The moist, inner lining of some organs and body cavities (such as the nose, mouth, lungs, and stomach). Glands in the mucous membrane make mucus (a thick, slippery fluid).

Detailed explanation-5: -The tongue is covered with mucous membrane, on top, on the sides, and also here in front, on the underside. The mucous membrane of the tongue is continuous with the mucous membrane that covers the floor of the mouth, and the alveolar process.

Detailed explanation-6: -Mucous membranes line many tracts and structures of the body, including the mouth, nose, eyelids, trachea (windpipe) and lungs, stomach and intestines, and the ureters, urethra, and urinary bladder.
