WebEach ring of the osteon is made of collagen and calcified matrix and is called a lamella (plural = lamellae). The collagen fibers of adjacent lamallae run at perpendicular angles to each other, allowing osteons to resist twisting forces in multiple directions (see figure 6.34a). WebJun 30, 2024 · Collagen fibers. Collagen fibers are tough, thick fibrous proteins found in dense connective tissues. It has many types but in dense connective tissue mainly type I collagen is present. Three stranded collagen molecules are packed together to form collagen fibrils and their alignment yield characteristic ultrastructural striations. Fibrils …
