Biology - Animal Tissue
The tissue found in animals have comparatively some different properties than the plant tissue.
Types of Animal Tissue
Animal Tissues are divided as −
Let’s discuss them in brief −
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.
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.
Connective tissues are further divided as −
Fibrous connective tissue
Skeletal connective tissue and
Fluid connective tissue
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.
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.
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 so.
