Classification of tissue

There are four main tissue in our body.they are as follows:-

1.  Epithelium tissue,
2. Connective tissue, 
3. Muscular tissue,
4. Nervous tissue.

1. Epithelium Tissue :-

The coverings in the body is formed by this tissue .it also helps in many purpose like adsorption, excretion, secretion, filtration, and sensory reception etc,.

Types of Epithelium tissue

there are two main type of Epithelium tissue present in our body:-

• Simple Epithelium Tissue:- Is the tissue made up of single layer of cell.
• Stratified Epithelium :- is the tissue made up of two or more than layer of cell .

2.Connective Tissue:- this is the tissue most abundantly found in the body .it helps in protect,support, and bind together.

there are four  type of connective tissue :-

1. Connective tissue proper 

   a. Loose Connective Tissue 

      i. Areolar 

      ii. Adipose 

      iii. Reticular 

   b. Dense Connective Tissue 

     i. Dense regular

     ii. Dense irregular 

     iii. Elastic 

2. Cartilage 

   a. Hyaline 

   b. Elastic 

    c. Fibrocartilage 

3. Bone (osseous tissue) 

4. Blood.

 3.Muscular Tissue :- it is soft tissue which composes of muscles and helps in contraction.

     there are four type of tissue 

     i.cardiac 

     ii. smooth.

     iii. skeletal.

     4. Nervous Tissue:- nervous tissue is main part of nervous .it is also main part of central nervous system (cns) and  peripheralnervous system(pns).
