Epithelial is one of the four types of tissues in the body. There is also muscular, nervous, and connective tissues. The best way to describe epithelial tissues is that they occur in parts of the body that need protection from the external environment. An analogy would the be the tiles on the space shuttle.

Characteristics of epithelial tissue:
Epithelial tissue lies on a basement membrane. That means that underlying the cells that are the cellular component of the epithelial tissue, there is a layer of acellular ("a-" means not, so "acellular" means not cellular) material. This basement membrane can be thought of as a sticky layer to keep the epithelial cells attached to whatever underlies them. The bottom edge of the epithelial tissue abuts the basement membrane; this bottom edge is called the basal surface. The edge of the epithelial tissue that faces the lumen (or the outside world) is called the apical surface.
Other characteristics:
1. Cells within this tissue readily divide to make more cells. This helps this tissue recover after any sort of abrasions occur.
2. This tissue does not have any vasculature. This means that there are no blood vessels within it. This should make sense, since epithelial tissue is likely to get damaged by material moving against it-- and you don't want to bleed everytime something bangs into your skin or everytime you swallow something rough.
3. The cells within this tissue are firmly attached to each other. As a border-tissue, if the cells weren't adherent to one another, it would be a leaky border. This would be no good-- liquids from inside of us would drip out! Yuck! So the cells all make the type of junctions with each other called tight junctions.

Where is epithelial tissue found in the body?
Epithelial tissue is found throughout the body in your skin, organs and cells.
Which type of tissue will be found immediately below the skin and most epithelial layers?
The type of tissue that will be found immediately below the skin and most epithelial layers is connective tissue. This tissue provides support, structure, and nourishment to the overlying epithelial cells.
What kind of tissue is found in the jaw bone epithelial connective nerve or muscle?
What kind of tissue is found in the jaw bone, epithelial connective nerve or muscle?The kind of tissue found in the jaw bone is connective tissue.
What are the type of epithelial tissue found in the epidermis and dermis of the skin?
The type of epithelial tissue that is found in the epidermis of the skin is called stratified squamous epithelium. The dermis consists of connective tissue.
Epithelial tissue is found where?
In the lining of the respiratory tract.
Is Epithelial tissue found in adult organs?
Yes it is.
What are examples of a type of tissue found in animals?
Muscle tissue Connective tissue Nervous tissue Epithelial tissue
Which living tissue in the human body is the only tissue with no blood vessels and where is it found?
epithelial tissue
What epithelial tissue is found in areas subject to friction and abuse?
Stratified squamous epithelium is the kind of epithelial tissue found in areas subject to friction and abuse. For example, this type is found in the esophagus.
Tissue that covers organs?
The tissue that covers organs is called epithelial tissue. These cells form a protective barrier against infections, regulate the passage of molecules, and provide a smooth surface for organs to function properly. Epithelial tissue can be found lining internal cavities and organs throughout the body.
What are the major tissue types found in the auricle?
The major tissue types found in the auricle are epithelial tissue, connective tissue, and adipose tissue. The epithelial tissue covers the surface of the auricle, while the connective tissue provides structure and support. Adipose tissue is found underneath the skin and helps cushion and protect the auricle.
What type of tissue most easily regenerates after injury?
epithelial tissue, connective tissue
