Squamous epithelial tissue is the type of tissue forms the upper layer of the epidermis.

The epidermis consists of stratified squamous epithelium, a continuous layer of cells that covers the body's surfaces, this boundary layer can control the movement of substances between the external and internal environment.

The stratified epithelium is made up of several layers of cells, as general functions are to provide a barrier of greater protection and certain degrees of waterproofing.

We can divide it into:

  • Stratified squamous epithelium: several layers of squamous cells whose surface layer is squamous to provide a strong barrier against mechanical damage and provide waterproofing.

In the case of the skin, hair and nails, they can produce keratin, a strong fibrous protein, which replaces the nucleus and cytoplasm of the cell.

  • Stratified cubiodal epithelium: we can only find it in the ducts of the sweat glands.

  • Stratified columnar epithelium: It is found, for example, in areas of the pharynx and in some parts of the male urethra.

The structure of the epithelial tissue remains stable thanks to a well-regulated dynamics between the proliferation, differentiation and desquamation processes faced by its cells.

Therefore, we can conclude that squamous epithelial tissue is the type of tissue forms the upper layer of the epidermis.
