Question

Modification and Examples of Pseudostratified epithelium?​

Answer 1

Answer:

Epithelial tissues are thin tissues that cover all the exposed surfaces of the body. They form the external skin, the inner lining of the mouth, digestive tract, secretory glands, the lining of hollow parts of every organ such as the heart, lungs, eyes, ears, the urogenital tract, as well as the ventricular system of the brain and central canals of the spinal cord.

The cells making up epithelia are often closely bound to one another through specialized structures called tight junctions. They are also free from blood vessels and nerves and are supported by a connective tissue called the basement membrane. They have polarity with a distinct basal domain facing the basement membrane and the other apical surface facing the lumen of an organ or the external environment.

Answer 2

Modification of Pseudostratified epithelium :-

Pseudo-stratified columnar ciliated glandular epithelium that is in this tissue Cilia is present free end on of the long cells and the goblet cells are also present in this epithelial.

In parts for example where this type of tissue is present are trachea, respiratory tract, bronchioles and as the epithelium of nasal chamber.
