What are tissues?
Tissue is a group of cells that have similar structure and that function together as a unit. A nonliving material, called the intercellular matrix, fills the spaces between the cells. This may be abundant in some tissues and minimal in others.
What are the three regions of the epithelial cell membrane?
Epithelial cell membranes have three regions (domains) different in structure and function; apical, lateral and basal. This feature is called membrane polarity.
What is the epithelial tissue?
Epithelial tissue is one of the four tissue types. It is found lining the inner and outer body surfaces and comprising the parenchyma of the glands. It is divided into surface (covering) and glandular (secreting) epithelium. Surface epithelium consists of one or more cell layers, stacked over a thin basement membrane.
What is the cuboidal epithelium?
Simple cuboidal epithelium – a single layer of cube-shaped cells. This type of epithelium offers greater protection than simple squamous due to its increased thickness. It also has secretory, absorptive and excretory functions because of its organelle rich cytoplasm. Simple cuboidal epithelium is found in organs with these functions, such as the ducts of the salivary glands, liver, pancreas and other exocrine glands. It forms thyroid follicles, kidney tubules, seminiferous tubules of male testis, and covers the surface of the ovaries (germinal epithelium).
Why doesn't the epithelium have blood vessels?
This is one reason why epithelia doesn't have blood vessels, as abrasion could result in tearing of the vessel and bleeding. Epithelia specialized for protection, such as the stratified squamous keratinized epithelium of the skin, are multilayered and have a high cell renewal rate. This means that they repair quickly after injury.
What is stratified epithelium?
Stratified epithelium consists of two or more cell layers. Based on the shape of their most apical cell layer, they are further classified into squamous, cuboidal and columnar. There are also two types of specialized stratified epithelium: keratinized and transitional.
What is pseudo-seudostratified epithelium?
Pseudostratified epithelium is a type of simple columnar epithelium. It is termed “pseudo” because, although single, it appears to have multiple layers. All the cells are attached to the basement membrane but not all of them reach the free surface, thus forming a sheet of cells with different heights and irregularly located nuclei.
Which type of epithelium is responsible for detecting smells?
These epithelial receptor cells have apical cilia which detect the chemical signals of incoming odors. They pass that signal to the olfactory nerve (CN I) which transmits the information about the smell to the central nervous system. Other receptor epithelia include stratified columnar epithelia of the retina, taste buds , organ of Corti and ampullae in the inner ear.
What are the different types of epithelial cells?
The common types are simple squamous cells, simple cuboidal cells, simple columnar, stratified squamous, stratified cuboidal, stratified columnar and pseudostratified columnar.

In addition, they are in glands. Epithelial cells have many roles in an organism, such as playing a part in secretion, absorption, sensation, protection and transport.
How do epithelial cells help you stay cool?
This keeps out environmental problems like dirt, bacteria and viruses. Additionally, epithelial cells can help you stay cool by allowing you to sweat in hot conditions. Their ability to stretch allows your skin to move and stay flexible.
What are the cells that line the body?
It consists of epithelial cells, which line the surfaces of the body. Epithelial cells are tightly packed in various organ systems, such as your skin. You can also find these cells lining the airways and respiratory system, blood vessels, urinary tract, digestive tract and kidneys.
Why are epithelial cells important?
Epithelial cells have important roles in secretion and absorption. They help multicellular organisms maintain a stable internal environment.
What happens when epithelia are damaged?
However, when something goes wrong with the epithelia, it can cause problems ranging from infertility to cancer.
Which side of the epithelial cell faces the underlying tissue?
First, these cells are polarized. The top or apical side is the one that faces the cell surface, while the bottom or basal side faces the underlying tissue.
Serous Membranes
Serous membranes line body cavities that lack openings to the outside of the body. They consist of simple squamous epithelium (a mesothelium) and loose connective (areolar) tissue and secrete watery serous fluid, which lubricates membrane surfaces. Serous fluid contains enzymes.
Mucous Membranes
Mucous membranes are also known as mucosae. These membranes line body cavities that open to the outside of the body, including the nose and mouth as well as digestive, respiratory, urinary, and repro-ductive tubes. Mucous membranes consist of epithe-lium above the loose connective tissue (the lamina propria), with goblet cells that secrete mucus.
Cutaneous Membrane
The cutaneous membrane is the skin, which cov-ers the body surface. It consists of a keratinized strat-ified squamous epithelium, known as the epidermis. This is firmly attached to a thick connective tissue layer known as the dermis.
Synovial Membranes
Synovial membranes form an incomplete lin-ing within the cavities of synovial joints. They are entirely made up of loose connective tissues. Syno-vial membranes may be the inner of the two layers of the articular capsule of a synovial joint, with a free smooth surface lining the joint cavity.

Serous Membranes. Serous membranes line body cavities that do not open directly to the outside, and they cover the organs located in those cavities. Serous membranes are covered by a thin layer of serous fluid that is secreted by the epithelium.
How does the serous membrane differ from other membranes?from papertrell.com
It differs from other membranes because it is exposed to air and is dry.
