Best Short Notes on Animal Tissue 2023

Animal Tissue

The tissue found in animals has comparatively different properties than the plant tissue.


Types of Animal Tissue :-

Animal tissues are divided into different categories.

➖Epithelial Tissue

➖Connective Tissue

➖Muscular Tissue

➖Nervous Tissue

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 dissimilar body systems separate.

➖Epithelial tissue cells are closely packed (as shown in the image above) and create a continuous layer.

Connective Tissue

➖Connective tissues are made up of cells that 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 an example of fibrous connective tissue.

➖Bone is an example of a skeletal connective tissue.

➖Bone forms the framework and provides support 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), white blood cells (WBCs), and platelets remain suspended.

Muscular Tissue

➖Muscular tissue primarily consists of elongated cells, also known as muscle fibres.

➖The muscular tissue is accountable for the movements in our body.

➖The muscular tissue contains particular 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 comprise the nervous tissue.

➖Cells of the nervous tissue are highly particular and sensitive for being stimulated and 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.
