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 −

o Epithelial Tissue

o Connective Tissue

o Muscular Tissue

o 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 are further divided as −

o Fibrous connective tissue

o Skeletal connective tissue and

o 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.
