Simple and compound epithelial tissues
epithelial tissue, connective tissue
Epithelial tissue does not exhibit polarity.
Epithelial tissue is the type of tissue that always has a free surface exposed to the internal or external environment. This tissue serves as a protective barrier or lining for organs and cavities in the body.
How is the function of nerve tissue different from that of epithelial tissue?

epithelial tissue
An epithelial membrane is a thin layer of tissue that covers organs, lines cavities, and forms the outer layer of the skin. It consists of epithelial cells attached to an underlying connective tissue layer. Epithelial membranes serve to protect, secrete, and absorb substances.
The presence of different types of cells and their positioning within the epithelial layer determine the distance from the free surface to the basal surface in epithelial tissue. Additionally, the function of the epithelial tissue in a specific organ or structure can influence the thickness of the tissue layer.
The four main types of human tissue are epithelial tissue, connective tissue, muscle tissue, and nervous tissue. Epithelial tissue covers body surfaces and lines cavities. Connective tissue supports and connects various body parts. Muscle tissue is responsible for movement, while nervous tissue transmits and processes information in the body.
Epithelial tissue are closely connected and have a basal membrane, even though not all epithelial cells are necessarily connected to the basal membrane. The so called simple epithelial tissue subgroup does.

Epithelial tissue covers the body surface. It serves as a protective barrier against physical, chemical, and microbial damage and helps regulate the exchange of substances between the body and its environment.
