MICROANATOMY

Detailed explanation-1: -Connective tissues are made up of a matrix consisting of living cells and a non-living substance, called the ground substance. The ground substance is made of an organic substance (usually a protein) and an inorganic substance (usually a mineral or water). The principal cell of connective tissues is the fibroblast.

Detailed explanation-2: -Its principal constituents are large carbohydrate molecules or complexes of protein and carbohydrate, called glycosaminoglycans (formerly known as mucopolysaccharides).

Detailed explanation-3: -The main fibrous proteins that build the extracellular matrix are collagens, elastins, and laminins. These are all relatively sturdy protein macromolecules. Their sturdiness lends the extracellular matrix its buffering and force-resisting properties that can withstand environmental pressures without collapsing.

Detailed explanation-4: -Blood is a fluid connective tissue. The blood cells remain embedded in a fluid extracellular matrix, which is called plasma.
