GENERAL HISTOLOGY

Detailed explanation-1: -Stratified squamous epithelium: This type of epithelium usually has protective functions, including protection against microorganisms from invading underlying tissue and/or protection against water loss. The outer layer of your skin (the epidermis) is made of stratified squamous epithelial cells.

Detailed explanation-2: -Epithelial tissues are widespread throughout the body. They form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands. They perform a variety of functions that include protection, secretion, absorption, excretion, filtration, diffusion, and sensory reception.

Detailed explanation-3: -Stratified squamous epithelial cells are found in a number of organs, including the skin epidermis and the thymus.

Detailed explanation-4: -The function of stratified columnar epithelium is mainly the protection of underlying tissues with multiple layers of epithelial cells. Also, they perform secretion.

Detailed explanation-5: -Besides the skin, the keratinized stratified squamous epithelium is also found in areas of the oral mucosa that are subject to frictional stress, such as the gingiva, hard palate and parts of the tongue. The keratinized epithelium in the oral mucosa is similar to the epidermis, except that it lacks the stratum lucidum.
