Histology

Histology

Tissues:
are groups of similar cells that perform a particular function.
There are four types of tissues found in animals:
Epithelial tissue, Connective tissue, Muscle tissue, Nervous tissue.
Tissue may found of one type of cell or more than one type.

Epithelial Tissue is presented in two forms:

1. Covering Epithelia
2. Glandular Epithelia

Covering Epithelial Tissue is classified into:
1. Simple Epithelium:
2. Stratified Epithelium:

Simple Epithelium is classified according to the morphology of the cell into

1. Simple Squamous Epithelium
2. Simple Cuboidal Epithelium
3. Simple Columnar Epithelium



4. Pseudostratified Epithelium





Stratified epithelium is classified into the following types based on the shape of the cells:
Stratified squamous epithelium
Stratified cuboidal epithelium
Stratified columnar epithelium
Transitional epithelium

Stratified squamous epithelium

2. Stratified cuboidal epithelium

3-Stratified columnar epithelium

Transitional epithelium
