Connective tissue proper
Connective tissue consists of cells and an extracellular matrix composed of fibers (collagen, reticular and elastic), ground substance and tissue fluid. Ground substance, primarily proteoglycans, is present as a gel in connective tissue proper, where it surrounds cells and fibers, and serves as padding between other tissues and organs of the body. 400x, 400x
