Hello students, in this question we have been provided with images of section of pseudo stratified columnar epithelium.
00:09
We need to name the pointed parts.
00:13
Pseudo stratified columnar epithelium is a type of epithelial tissue found in various parts of the body such as respiratory tract and reproductive system.
00:22
Although it appears stratified with multiple layers of cells, it has actually a single layer of cells at varying height giving it a pseudo stratified appearance.
00:32
First let us discuss about the types of cells present in the pseudo stratified epithelium.
00:38
The first one is columnar cells.
00:43
These are elongated cells with which make up the majority of the epithelial tissue.
00:50
Here as you can see these are the elongated cells.
00:53
So these are columnar cells.
00:55
Next is goblet cells.
00:57
Scattered among the columnar cells, goblet cells are specialized secretory cells that produce and secrete mucus.
01:05
They play an important role in protecting and lubricating the epithelial surface.

Here this is a goblet cell...
