Connective tissue is composed of three main components:
Cells: The primary cells found in connective tissue include fibroblasts, adipocytes, mast cells, macrophages, and leukocytes. Each cell type has specific functions essential for tissue maintenance and repair. Fibers: The ECM contains three types of fibers - collagen, elastic, and reticular fibers. Collagen fibers provide tensile strength, elastic fibers allow for stretch and recoil, and reticular fibers form a supportive meshwork. Ground Substance: This amorphous material fills the space between cells and fibers. It consists of water, proteoglycans, and glycosaminoglycans, which facilitate nutrient diffusion and provide structural support.
