Keratinized surfaces are protected from absorption by keratin protein. Keratinized epithelium has keratin deposited on the surface which makes it impermeable and dry. Examples of keratinized stratified squamous epithelium include skin, the epidermis of the palm of the hand, and the sole of the foot, [3] and the masticatory mucosa.
Masticatory mucosa, keratinized stratified squamous epithelium, found on the dorsum of the tongue, hard palate, and attached gingiva. Specialized mucosa , specifically in the regions of the taste buds on lingual papillae on the dorsal surface of the tongue; contains nerve endings for general sensory reception and taste perception.
Stratified squamous epithelium: is simulated by oral keratinocytes cultured in a medium containing keratinocyte growth factors such as the epidermal growth factor (EGF). [ 1 ] To obtain the best results, the type and origin of the fibroblasts and keratinocytes used in oral mucosa tissue engineering are important factors to hold into account.
Stratified squamous, non-keratinized - reproductive - female: vaginal epithelium: Stratified squamous, non-keratinized - reproductive - female: labia majora: Stratified squamous, keratinized - reproductive - male: tubuli recti: Simple cuboidal: germinal epithelium (male) reproductive - male: rete testis: Simple cuboidal - reproductive - male ...
The topmost layer comprises stratified squamous epithelium which is bordered by ciliated pseudostratified epithelium. The inner-lining surface of this squamous epithelium is covered by a layer of mucus (acting as a mucociliary clearance), which is composed of two layers: a mucinous layer and serous layer. Both mucus layers provide viscous and ...
According to Klein, the mucous membrane on the nasal surface of the soft palate in the fetus is covered throughout by columnar ciliated epithelium, which subsequently becomes squamous; some anatomists state that it is covered with columnar ciliated epithelium, except at its free margin, throughout life.
While the junctional epithelium is a stratified and thin epithelium that is attached to the tooth surface, the epithelium of the gingival sulcus is stratified squamous and thicker non-keratinised. Presence of Rete Pegs which may be prominent epithelial ridges can also be found in the gingival epithelium that is a stratified squamous, thick and ...
The epidermis, "epi" coming from the Greek language meaning "over" or "upon", is the outermost layer of the skin. It forms the waterproof, protective wrap over the body's surface, which also serves as a barrier to infection and is made up of stratified squamous epithelium with an underlying basal lamina.
