Name the various type of animal …

Animal tissues are of four types, viz. epithelial tissue, connective tissue, muscular tissue and nervous tissue.

Epithelial Tissue

Epithelial tissues form the protective covering and inner lining of the body and organs. These tissues were the first to evolve during evolution and were first formed during embryonic development. They develop from the ectoderm, mesoderm and endoderm of the embryo.

Connective Tissue

Connective tissues develop from the mesodermal cells of the embryo. they support and bind other tissues in the body. These are made up of three components:

• Intercellular Matrix: It is made up of mucopolysaccharide, specifically hyaluronic acid.
• Cells: The major cells include fibroblasts, adipocytes, plasma cells and mast cells.
• Fibres: Connective tissues are made up of three types of fibres, namely, collagen fibre, elastic fibre, reticular fibre.

Muscular Tissue

The muscular tissue develops from the mesoderm of the embryo. It is classified into three types:

• Cardiac
• Smooth
• Skeletal
