Which of the following is example of epithelial tissue?
Types of Epithelial Tissue
| Epithelial Tissue Cells | |
|---|---|
| Cells | Locations |
| Stratified cuboidal epithelium | Sweat glands, salivary glands, and mammary glands |
| Stratified columnar epithelium | The male urethra and the ducts of some glands. |
| Transitional epithelium | Lines the bladder, urethra and ureters |
What type of tissue is epithelial?
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.
What are the examples of epithelial and connective tissue?
Epithelial tissue is found in various organs like skin, buccal cavity, the lining of blood vessels, body cavities, glands, and their ducts. Connective tissue is the tissue that forms the bones, cartilages, adipose tissue, reticular tissue, and the blood.
What are the 4 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 two main types of epithelial tissue?
Squamous epithelium has cells that are wider than they are tall. Cuboidal epithelium has cells whose height and width are approximately the same. Columnar epithelium has cells taller than they are wide.
What is the main function of epithelial tissue class 9?
Depending on the number of layers of cells it is composed of, the epithelium has been divided into the simple epithelium and compound epithelium. The main functions of epithelial tissue are protection, secretion, absorption, and sensation.
How many types of epithelial tissues are there class 9?
They are further classified into two types i.e ciliated columnar epithelium and glandular columnar epithelium. 2. Based on Layer Epithelial Tissue is Classified into Two Types, They are: Simple Epithelial/Unilayered Epithelial: Having a single layer.
Which is the best description of epithelial tissue?
Most epithelial tissue is described with two names. The first name describes the number of cell layers present and the second describes the shape of the cells. For example, simple squamous epithelial tissue describes a single layer of cells that are flat and scale-like in shape.
Is there intercellular material in the epithelium?
There is little intercellular material present between cells. There are specialised junctions present between the cells of the epithelium, that link individual cells. Epithelial cells form membranes. The epithelial membrane consists of a layer of epithelial tissue and has underlying connective tissue.
Where are transitional epithelias found in the body?
Transitional epithelia are found in tissues such as the urinary bladder where there is a change in the shape of the cell due to stretching.
Which is an example of a keratinized epithelium?
It is therefore found where body linings have to withstand mechanical or chemical insult. In keratinized epithelia, the most apical layers (exterior) of cells are dead and and contain a tough, resistant protein called keratin. An example of this is found in mammalian skin that makes the epithelium waterproof.
What are the four types of epithelial tissue?
According to the shape of epithelial cells and the numbers of cells layers, covering epithelial tissues are divided into four different types – #1. Simple epithelium tissue – have a single layer of epithelial cells resting on the basement membrane. #2.
There is little intercellular material present between cells. There are specialised junctions present between the cells of the epithelium, that link individual cells. Epithelial cells form membranes. The epithelial membrane consists of a layer of epithelial tissue and has underlying connective tissue.
How is the basement layer of epithelial tissue identified?
The basement layer is non-cellular in nature and helps to cement the epithelial tissue to the underlying structures. Epithelial tissues are identified by both the number of layers and the shape of the cells in the upper layers.
How are epithelial cells separated from connective tissue?
Epithelial cells are aligned into one or more rows, separated by thin layers of extracellular matrix. The deepest row (basal domain) produces a layer of specialized extracellular matrix called the basement membrane. This membrane demarcates the epithelial tissue from the underlying connective tissue.
