Detailed explanation-1: -Oral mucosa consists of two layers, the surface stratified squamous epithelium and the deeper lamina propria. In keratinized oral mucosa, the epithelium consists of four layers: Stratum basale (basal layer) Stratum spinosum (prickle layer)
Detailed explanation-2: -The mucosa consists of the epithelium itself and also the supporting loose connective tissue, called lamina propria, immediately beneath the epithelium. Deeper connective tissue which supports the mucosa is called the submucosa.
Detailed explanation-3: -As seen with the electron microscope, the basement membrane is composed of two layers, the basal lamina and the reticular lamina. The underlying connective tissue attaches to the basal lamina with collagen VII anchoring fibrils and fibrillin microfibrils.
Detailed explanation-4: -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.
