Which of the following statements is true for epithelial tissue?
Epithelium tissue are closely packed cells which make up the lining of external surface and the internal lining of organs. It has a basement membrane made of mucopolysaccharide and collagen. There are gap junctions between adjacent cells to hold the cells together and facilitate cell-cell interactions.
What are epithelia?
The term epithelium refers to layers of cells that line hollow organs and glands. It is also those cells that make up the outer surface of the body.
What are 4 characteristics of epithelial tissue?
Characteristics of Epithelial Tissues
- Covers and lines body surfaces.
- Cells are densely packed together with minimal amount of intercellular substance.
- Cells are firmly attached by intercellular junctions.
- Cells rest on a basement membrane partly derived from underlying connective tissue.
Which of the following is an epithelial tissue?
The lining of the mouth, lung alveoli and kidney tubules are all made of epithelial tissue. The lining of the blood and lymphatic vessels are of a specialised form of epithelium called endothelium.
What are epithelia tissue?
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. Epithelial cells may be squamous, cuboidal, or columnar in shape and may be arranged in single or multiple layers.
What is the difference between epithelial and epithelia?
is that epithelia is while epithelium is (anatomy) a membranous tissue composed of one or more layers of cells which forms the covering of most internal and external surfaces of the body and its organs: internally including the lining of vessels and other small cavities, and externally being the skin.
What are the 4 types of epithelial tissue?
Types of epithelial tissue
- Cell shape: squamous, cuboidal, columnar.
- Cell layers: simple (one layer), stratified (multiple layers).
What are the 7 characteristics of epithelial tissue?
Characteristics of Epithelial Layers Epithelial tissue is composed of cells laid out in sheets with strong cell-to-cell attachments. These protein connections hold the cells together to form a tightly connected layer that is avascular but innervated in nature.
What are some examples of epithelial tissue?
Some examples of epithelial tissue include:
- The outer layer of your skin (epidermis).
- The lining of your intestines.
- The lining of your respiratory tract.
- The lining of your abdominal cavity.
- Your sweat glands.

What is epithelial tissue and its types?
There are 8 types of epithelial tissues. Simple squamous, Stratified Squamous, Simple Cuboidal, Stratified Cuboidal, Simple Columnar, Stratified Columnar, Pseudostratified Columnar and Transitional epithelia or urothelium.

What is the difference between epithelial tissue and epithelium?
Cells in epithelial tissue or epithelium (epithelia; plural) are arranged in continuous sheets, in either single or multiple layers. Covering epithelium is the tissue that forms the outer covering of the skin and most internal organs like blood vessels and body cavities.
What is a epithelia?
The term epithelium refers to layers of cells that line hollow organs and glands. It is also those cells that make up the outer surface of the body.
What is difference between epithelial and endothelium?
Endothelial cells are a specialized type of epithelial cells. The main difference between epithelial and endothelial cells is that epithelial cells line both internal surfaces and external surfaces of the body whereas endothelial cells line the internal surfaces of the components of the circulatory system
What are the types of epithelial tissues?
Epithelial cells may be squamous, cuboidal, or columnar in shape and may be arranged in single or multiple layers. Simple cuboidal epithelium is found in glandular tissue and in the kidney tubules. Simple columnar epithelium lines the stomach and intestines.
What are the four types of epithelial tissues and can you describe their function?
Characteristics of Epithelial Tissues
- Covers and lines body surfaces.
- Cells are densely packed together with minimal amount of intercellular substance.
- Cells are firmly attached by intercellular junctions.
- Cells rest on a basement membrane partly derived from underlying connective tissue.

What are 5 general characteristics of epithelial tissue?
Despite there being many different types of epithelial tissue all epithelial tissue have just five characteristics, these are cellularity, polarity, attachment, vascularity, and regeneration. Cellularity as the name suggests means that the epithelium is made up almost entirely of cells.
What are the characteristics of epithelial tissue class 9?
1)They form the outer layer of skin. They protect underlying cells from drying,injury,chemical effects etc. 2)Form lining of mouth and alimentary canal,protect these organs. 3)Help in absorption of water and nutrients.
