Stratified Squamous Epithelium Keratinized Thick Skin

This stratified squamous epithelium shows a thickened layer of squamous cells that have undergone heavy keratinization cornification and have since died. Underlying cell layers can be made of cuboidal or columnar cells as well.

If we just want to look at stratified squamous keratinized epithelium we look at skin from one of the few areas of the body that does not have hair.

Stratified squamous epithelium keratinized thick skin. Although stratified squamous keratinized epithelium covers the entire surface of the body most of it also includes hair which makes the basic tissue structure harder to see. Keratinized epithelium is composed of numerous layers of dead squamous cells which are specially structured to be waterproof and reduce evaporation from underlying tissues. Stratified keratinized squamous epithelium is very thick dermal papillae are highly developed and stratum corneum is thicker than in other body places.

A medium power view of the skin epithelium the epidermis reveals the multiple cells layers of this stratified squamous epithelium. This tissue is from the palm of the hand palmar skin. Keratinzed stratified squamous epithelium is important in tissues exposed to regular physical abrasion as well as the possibility of desiccation drying out and water loss.

The bluish color of the keratin on the upper part and of the connective tissue in the lower part is because of the staining protocol. Keratinized surfaces are protected from abrasion by keratin and kept hydrated and protected from dehydration by glycolipids produced in the stratum granulosum. A pink eosinophilic layer called the stratum lucidum lies between the epithelium proper and the keratin layer stratum corneum.

As these cells age they create a layer of keratinized epithelium. Stratified squamous epithelia are tissues formed from multiple layers of cells resting on a basement membrane with the superficial layer s consisting of squamous cells. Examples of keratinized stratified squamous epithelium include epidermis of the palm of the hand and sole of the foot and the masticatory mucosa.

Skin of the upper lip of a rat. The epithelial tissue functions in secretion excretion absorption and protection. Top layer of the skin composed of a few layer of stratified squamous with no nucleus.

The stratified squamous keratinized epithelium of thick skin has a very thick layer above compared to thin skin. The stratified squamous epithelium also known as epidermis makes up the outer layer of skin and it serves an important protective function. Stratum granulosum the last nucleated layer of the skin up on closer look the members of the layer seems granulated.
