Types of tissues
1)Epithelial tissue
2)Connective tissue
3)Muscular tissue
4)Nervous tissue.


Epithelial tissue: This tissue is an upper most tissue covering all the organs or body. This tissue based on need is of different types as simple epithelium, squamous epithelium, columnar epithelium etc.



Connective tissue: This tissues as the name indicates, is in connecting position in between tissues. This is many types like adipose tissues, reticular tissue etc.
This connective tissue is divided as
Loose connective tissue. (Areolar tissue, adipose tissue)
Dense connective tissue.
Cartilage tissue
Bone tissue
Liquid connective tissue (examples of tissue is blood, W.B.C’s, lymph)


Muscular tissue: As the name indicates, this tissues makes muscles of the body. This tissue is of 3 types as
a) Skeletal muscle tissue
b) Cardiac tissue
C) Smooth muscle tissue
Striated muscles are present attached to skeletal system, especially long bones. They also have bands or striation along the length. They are voluntary i.e. they are under the control of our will. They help in movement from one place to another.
Cardiac muscles are present in the heart. They like skeletal muscles have striations in them. But the difference is, they have branches. This muscle helps to pump blood by the heart.
Smooth muscles are spindle or cone shaped in structure. They help in contraction and relaxation of man organs like lungs, stomach, uterus etc.


Nervous tissue: This tissue is mostly present in the entire nervous system including brain and spinal cord. It has two types of tissue as nervous cell and neuroglia.


The nerve cells are the longest cells in the body. They can be up to few meters. They transmit impulses from brain to other body parts and vice-verse. This tissue controls the whole body by conduction of impulses across the body. The tissue operates by use of bio-molecular chemical substances called as neurotransmitters.
