The major types of connective tissue are connective tissue proper, supportive tissue, and fluid tissue. e.g. Most abundant are the fibres composed of the protein collagen. Other tissues are classified loose connective tissue proper and have fewer extracellular protein fibers and more ground substance (the extracellular material surrounding the protein fibers), making the tissues spongier but more fragile. Like all tissue types, it consists of cells surrounded by a compartment of fluid called the extracellular matrix (ECM). ii. ligaments (which link bone to bone at joints) and tendons (connections between bones or cartilage and muscle).

Connective tissue proper is populated by a variety of cell types that differ in their morphology and function, mobility and origin. This type of connective tissue proper, with the help of its extracellular fibers, tightly binds epithelia to underlying tissue and physically supports the blood vessels and nerves that supply the subepithelial area. Transports fluids and dissolved materials. Instead of an aqueous extracellular matrix, the ground substance is mineralized and hard. They are a loose array of random fibers that has a wide variety of cell type. These structures help attach muscles to bones and link bones together at joints. Dense connective tissue is reinforced by bundles of fibers that provide tensile strength, elasticity, and protection. It is also critical for proper immune function. Type # 1.
