Cartilage is a connective tissue type that is principally composed of matrix, with relatively few cells. Collagens are the principal proteins of the extracellular matrix. They are structural proteins that provide tissues with strength and flexibility, and serve other essential roles as well.

Most connective tissues are vascularized (except cartilage). The extracellular spaces (space outside of cells) in connective tissue are referred to as the extracellular matrix. Connective tissue, therefore, is made up of cells and extracellular matrix. The extracellular matrix is composed of glycosaminoglycans and proteoglycans. It is variations in the composition of the extracellular matrix that determine properties of the connective tissue. Connective tissue is made up of: Fibrous components (collagen and elastin)

Connective tissue proper is classified as either loose irregular connective tissue or dense irregular connective tissue. 1  Loose irregular connective tissue contains numerous cells and a loose fiber arrangement in a moderately viscous fluid matrix.

Connective tissue connects, supports, binds, and separates organs and tissues, forming a framework to support body tissues and organs, for structural and metabolic purposes. In connective tissue, cells are few and dispersed -- they are not in close contact, as in epithelial tissue.

The Extracellular Matrix. Living tissues are not just accumulations of tightly packed cells. Much of a tissue's volume is made up of extracellular space ('extra-' meaning 'outside' or 'beyond,' as in 'extraterrestrial'). This void is filled with a complex meshwork called the extracellular matrix.

In no tissue is the extracellular matrix so well defined - or so easily studied - as in connective tissue, where the extracellular matrix is frequently more plentiful than the cells. Found throughout your body, connective tissue serves as the scaffolding for all other tissues.

The extracellular matrix is a meshwork of proteins and carbohydrates that binds cells together or divides one tissue from another. The extracellular matrix is the product principally of connective tissue , one of the four fundamental tissue types, but may also be produced by other cell types, including those in epithelial tissues.

Specialized connective tissue includes: 1  Dense regular connective tissue (found in tendons and ligaments) 2  Cartilage (a type of supporting connective tissue that consists of chondrocyte cells, collagen fibers, and elastic fibers; semi-solid or flexible matrix; includes hyaline cartilage, fibrocartilage, and elastic cartilage)

Connective tissue is made up of: 1  Fibrous components (collagen and elastin) 2  Glycosaminoglycans or GAGs (long chains of repeating disaccharide units; the main role is to support collagen) 3  Proteoglycans (GAGs attached to a core protein)

The extracellular matrix is made up of proteoglycans, water, minerals, and fibrous proteins. A proteoglycan is composed of a protein core surrounded by long chains of starch-like molecules called glycosaminoglycans. Production and Components. The components of the extracellular matrix are produced and organized by the cells that live within it.
