(a) Name the different types of epithelial tissues?
(b) What is basement membrane?
(a) There are three types of epithelial cells, which differ in their shape and function.
Squamous - thin and flat cells
Cuboidal - short cylindrical cells, which appear hexagonal in cross-section
Columnar - long or column-like cylindrical cells, which have nucleus present at the base
On the basis of the number of layers present, epithelial tissue is divided into the simple epithelium and stratified or compound epithelium.
Simple Epithelium- it is composed of one layer of a cell
Compound (Stratified) Epithelium- it is made up of two or more than two layers of cells
Glandular epithelium - is made up of cuboidal or columnar cells.
(b) Basement membrane is an extracellular fibrous membrane that is responsible for separating all epithelial tissues from the underlying tissue.
