Detailed explanation-1: -The alveolar mucosa and mucosa covering the floor of the mouth are attached loosely to the underlying structures by a thick submucosa. Elastic fibers in the lamina propria of these regions tend to restore the mucosa to its resting position after distention.
Detailed explanation-2: -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). Also called mucosa.
Detailed explanation-3: -Attached gingiva is a type of masticatory mucosa, lined with a para-keratinized stratified squamous epithelium ←. The increased amount of keratin, compared to alveolar mucosa, obscures the underlying blood supply, creating a lighter appearance (which can be described as whitish in the absence of melanin).
