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 −

    • 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 (as shown in the image given above) 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
  • 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.

Muscular Tissue
  • 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.

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.
