Detailed explanation-1: -Collagen: Collagen fibers are the strongest and most abundant of all the connective tissue fibers. Collagen fibers are fibrous proteins and are secreted into the extracellular space and they provide high tensile strength to the matrix.
Detailed explanation-2: -Bone. Bone is the hardest connective tissue. It provides protection to internal organs and supports the body. Bone’s rigid extracellular matrix contains mostly collagen fibers embedded in a mineralized ground substance containing hydroxyapatite, a form of calcium phosphate.
