Animal tissues are divided into four main types - epithelial, connective, muscular, and nervous tissue. Epithelial tissue forms protective barriers around organs and throughout the body. Connective tissue is made up of cells separated by an extracellular matrix and includes fibrous, skeletal, and fluid types such as tendons, bone, and blood. Muscular tissue consists of elongated muscle fibers that allow for body movement. Nervous tissue is composed of neurons in the brain, spinal cord, and nerves which transmit stimuli rapidly throughout the body.

2. Types of Animal Tissue
 Animal Tissues are divided as −
o Epithelial Tissue
o Connective Tissue
o Muscular Tissue
o Nervous Tissue

3. Epithelial Tissue
 Epithelial tissues are the covering and protective tissues in the animal body.
 Epithelial tissue covers almost all organs and cavities within the body.
 Epithelial tissue also forms a barrier to keep different body systems separate.
 Epithelial tissue cells are closely packed (as shown in the image given above)
and form a continuous layer.

4. Connective Tissue
 Connective tissues are made up of the cells those are separated by non-living
material, and known as an extracellular matrix.
 This matrix could be either liquid or rigid.

5.  Connective tissues are further divided as −
 Fibrous connective tissue
 Skeletal connective tissue and
 Fluid connective tissue

6.  Tendons are the example of fibrous connective tissue.
 Bone is an example of a skeletal connective tissue.
 Bone forms the framework and provide supports to the body.
 Blood is an example of fluid connective tissue.
 Blood has a fluid (liquid) matrix known as plasma.
 In plasma, the red blood cells (RBCs), the white blood cells (WBCs), and the
platelets are remaining suspended.

7. Muscular Tissue
 Muscular tissue largely consists of elongated cells, and also known as muscle
fibers.
 The muscular tissue is accountable for the movements in our body.
 The muscular tissue contains special proteins known as contractile proteins;
and this protein helps in contraction and relaxation and supports free
movement.

8. Nervous Tissue
 The brain, spinal cord, and nerves all are composed of the nervous tissue.
 Cells of the nervous tissue are extremely particular and sensitive for being
stimulated and then transmitting the stimulus swiftly from one place to
another within the body.
 The cells of nervous tissue are known as nerve cells or neurons.
 Nerve impulses allow us to move our muscles whenever we want to do
