Animal Tissue
ANIMAL TISSUE
Introduction
- The tissue found in animals have comparatively some different properties than the plant tissue.
Types of Animal Tissue
- Animal Tissues are divided as:
- Epithelial Tissue
- Connective Tissue
- Muscular Tissue
- Nervous Tissue
- Let’s discuss them in brief:
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 and form a continuous layer.
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.
- 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
- 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.
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 so.
