Tissue membranes a tissue membrane is a thin layer or sheet of cells that covers the outside of the body (for example, skin), the organs (for example, pericardium), internal passageways that lead to the exterior of the body (for example, abdominal mesenteries), and the lining of the moveable joint cavities. The mathematical system of calculus was famously developed independently in the 17th century by isaac newton and gottfried wilhelm leibniz although newton was born and worked in england, liebniz spent much of his life as an immigrant. Most epithelial tissues are essentially large sheets of cells covering all the surfaces of the body exposed to the outside world and lining the outside of organs epithelium also forms much of the glandular tissue of the body skin is not the only area of the body exposed to the outside.

Recall that there are four types of tissues: epithelial, connective, muscle and nerve epithelial tissues consists of sheets of conjoined cells that (1) line surfaces and (2) form glands as such, epithelial tissue covers the body, both inside and out, and affords a barrier property to the body.

Epithelial tissue, or epithelium, has the following general characteristics: epithelium consists of closely packed, flattened cells that make up the inside or outside lining of body areas there is little intercellular material. If you take a close look at epithelial cells using a microscope, you will see them tightly packed together this helps make a protective barrier for our bodies. Epithelial tissue (also epithelium) occurs throughout the body it is of two basic types: (1) that forming the epidermis (2) that forming the surfaces of the mucous and serous membranes it covers the body and also lines body cavities and hollow organs it is also one of the prominent tissue types in glands.
In zootomy, epithelium is a tissue composed of a layer of cells epithelium lines both the outside (skin) and the inside (eg intestine) of organisms the outermost layer of our skin is composed of dead squamous epithelial cells, as are the mucous membranes lining the inside of mouths and body cavities.

Review of the epithelial tissue and human skin easily learn about the types and characteristics of the epithelial tissues and their functions. 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. Perhaps because of its unique job of both protecting the outer body and lining internal organs, epithelial tissue has many characteristics that distinguish it from other tissue types. The epithelial tissue is one of the four main types of tissue structures of the human body, along with muscle tissue, nerve tissue and connective tissue tissues are cellular organizations with similar specializations.
