Epithelium (/ ˌ ɛ p ɪ ˈ θ iː l i ə m /) is one of the four basic types of animal tissue, along with connective tissue, muscle tissue and nervous tissue.It is a thin, continuous, protective layer of cells.Epithelial tissues line the outer surfaces of organs and blood vessels throughout the body, as well as the inner surfaces of cavities in many internal organs. Submucosal exocrine glands secrete mucus to facilitate the movement of particles along the body's various tubes, such as the throat and the intestines. Pseudo stratified columnar epithelium is especial type of simple epithelium. Characteristics. Keeping this in consideration, what are the four main functions of epithelial membranes? In other parts, epithelial tissues form the inner lining and external lining of body parts. Each is made of specialized cells that are grouped together according to structure and function. The L o phase of cellular membranes can be isolated from disordered lipids (L d phase) after treatment with 1 % Triton X-100 at 4 °C in which the L o phase forms the detergent-resistant membrane (DRM) fraction. The four types of membranes are: 1) cutaneous membranes; 2) serous membranes; 3) mucous membranes; and 4) synovial membranes. In biology, tissue is a cellular organisational level between cells and a complete organ. The skin is also a type of epithelial membrane, sometimes called cutaneous membrane, it is also formed by layers of epithelial tissue on connective tissue . Most mucosal membranes contain stratified squamous or simple columnar epithelial tissue types. They can be categorized into epithelial and connective tissue membrane. An epithelial membrane consists of a continuous sheet of cells, one or more layers thick, which is attached to the underlying connective tissue by a basement membrane. The first volume of this book is an inventory of physical transport processes occurring in cells, and this volume provides a closer look at how complex biological and physiological cell phenomena result from these very basic physical ... Epithelial tissue lines all our body surfaces both inside and out and it also forms glands. Epithelial cells can secrete the basal lamina, which is a layer that can provide support and help separate cells while acting like a filter. The skin is composed of two main layers: the epidermis, made of closely packed epithelial cells, and the dermis, made of dense, irregular connective tissue that houses blood vessels, hair follicles, sweat glands, and other structures.
