This connective tissue contains collagen fibers for flexibility and strength, and numerous elastic fibers that enable it to be stretched.

In contrast to loose connective tissue types where protein fibers are small and less abundant, dense connective tissues possess large, robust fibers that impart to these tissues considerable strength. Fibers are so numerous the extracellular matrix contains few if any open spaces where ground substance is visible.ense connective tissues contain either collagen or elastic protein fibers. Therefore, there are dense collagenous connective tissues and dense elastic types. The collagenous types, far more abundant, are also called fibrous or white connective tissues.
