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

Types of connective tissue fibers (released by subunits secreted by fibroblasts). 1  Collagen fibers, the most common fibers in connective tissue proper, are long, straight, and unbranched. 2  Elastic fibers contain the protein elastin and are branched and wavy, returning to their original length after being stretched. Dense connective tissue, or fibrous tissue, consists mainly of collagen fibers and found: 2  between the skeletal muscles and the tendons. 3  between bones and ligaments. 4  covering skeletal muscles and visceral organs.
