At a syndesmosis joint, the bones are more widely separated but are held together by a narrow band of fibrous connective tissue called a ligament or a wide sheet of connective tissue called an interosseous membrane. Adipose tissue is a form of loose connective tissue that is mostly found beneath the skin. The connective tissues include several types of fibrous tissue that vary only in their density and cellularity, as well as the more specialized and recognizable variantsbone, ligaments, tendons, cartilage, and adipose (fat) tissue.

They can be found all over the body. The extra cellular matrix has nearly amorphous ground substance which is made of glycoproteins with associated mucopolysaccharides. The orientation of fibers produces a regular or irregular pattern, resulting in dense regular and dense irregular tissues. The connective tissues perform the following functions: They attach organs and tissues together. Connective tissue is found deep and in-between the other three types of tissue: epithelium, nervous, and muscle tissue. When two or more organs interact physically and/or chemically to perform a common function, they form an organ system, for as the digestive system or respiratory system.
