Connective tissue

Connective tissue
A material made up of cells that form fibers in the framework providing a support structure for other body tissues. Cartilage and bone are specialized forms of connective tissue. Connective tissue is typically rich in what is called extracellular matrix (including collagen) and surrounds other more highly ordered tissues and organs. A tissue in medicine is not like a piece of tissue paper. It is a broad term that is applied to any group of cells that perform specific functions. A tissue in medicine need not form a layer. Thus, the bone marrow is also considered a tissue.

con·nec·tive tissue kə-.nek-tiv- n a tissue of mesodermal origin that consists of various cells (as fibroblasts and macrophages) and interlacing protein fibers (as of collagen) embedded in a chiefly carbohydrate ground substance, that supports, ensheathes, and binds together other tissues, and that includes loose and dense forms (as adipose tissue, tendons, ligaments, and aponeuroses) and specialized forms (as cartilage and bone)

the tissue that supports, binds, or separates more specialized tissues and organs or functions as a packing tissue of the body. It consists of an amorphous ground substance of mucopolysaccharides in which may be embedded white (collagenous), yellow (elastic), and reticular fibres, fat cells, fibroblast, mast cell, and macrophage. Variations in chemical composition of the ground substance and in the proportions and quantities of cells and fibres give rise to tissues of widely differing characteristics, including bone, cartilage, tendons, and ligaments as well as adipose tissue, areolar tissue, and elastic tissue.

the tissue that binds together and is the support of the various structures of the body. It is made up of fibroblasts, fibroglia, collagen fibrils, and elastic fibers, is derived from the mesoderm, and in a broad sense includes the collagenous, elastic, mucous, reticular, osseous, and cartilaginous tissue. Some authorities also include the blood. Two primary types are distinguished according to concentration of fibers: loose (TA, textus connectivus laxus) and dense.
