The protein elastin co-polymerizes with the protein fibrillin in elastic fibers. As in the walls of arteries, these fibers are frequently arranged into lamellar sheets. Ligaments are composed of dense, regular, and elastic tissue. Elastic fibers are flexible because they are generally unorganized; stretching them causes them to become more organized.
