. Connective Tissue Connective tissue develops from the mesoderm and is widely distributed in the body. There are three main classes namely Loose connective tissue, Dense connective tissue and Specialized connective tissue. Major functions of connective tissues are binding, support, protection, insulation and transportation Connective Tissues Loose Connective Tissues Dense Connective Tissues Specialised Connective Tissues .

The ‘Fibres’ of connective tissue provide support. Three types of fibres are found in the connective tissue matrix. They are collagen , elastic and reticular fibres . Connective tissues are of three types namely, Loose connective tissues (Areolar, Adipose and Reticular) and Dense connective tissues (dense regular, dense irregular and elastic) and Specialized connective tissues (cartilage, bone and blood).
Loose Connective Tissues In this tissue the cells and fibres are loosely arranged in a semi fluid ground substances. For example the Areolar connective tissue beneath the skin acts as a support framework for epithelium and acts as a reservoir of water and salts for the surrounding body tissues, hence aptly called tissue fluid. It contains fibroblasts, macrophages, and mast cells (Figure . ).
Adipose Tissue is similar to areolar tissue in structure and function and located beneath the skin. Adipocytes commonly called adipose or fat cells predominate and account for % of this tissue mass. The cells of this tissue store fats and the excess nutrients which are not utilised immediately are converted to fats and are stored in tissues. Adipose tissue is richly vascularised indicating its high metabolic activity.
While fasting, these cells maintain life by producing and supplying energy as fuel. Adipose tissues are also found
