GENERAL HISTOLOGY

Detailed explanation-1: -The connective tissues non cellular portion is known as the extracellular matrix (ECM), giving the physical scaffolding for the cells. The ECM is able to hold water, provide appropriate hydration of the tissue and form part of a selective barrier to the external environment.

Detailed explanation-2: -The extracellular matrix of connective tissue is composed of fibers and ground substance. In ordinary connective tissue, the principal fiber type is collagen (the most abundant protein in the body), with elastic fibers as a minor element; ground substance consists mainly of water.

Detailed explanation-3: -In biology, the extracellular matrix (ECM), also called intercellular matrix, is a three-dimensional network consisting of extracellular macromolecules and minerals, such as collagen, enzymes, glycoproteins and hydroxyapatite that provide structural and biochemical support to surrounding cells.

Detailed explanation-4: -The matrix of connective tissue is the part of the tissue that is non-cellular, and is also known as the ground substance. It is the substance in which the living cells are embedded, and also contains the fibers that are a part of the tissue, which are typically collagen.
