collagen fibers

collagen fibers
collagenous fibers the soft, flexible, white fibers that are the most characteristic constituent of all types of connective tissue. They consist of the protein collagen and are composed of bundles of fibrils that are in turn made up of smaller unit fibrils; see also collagen fibrils, under fibril. In describing the hierarchy of arrangement of collagen structure, the terms fiber and fibril are sometimes loosely interchanged.

Loose connective tissue in the mesentery in a whole mount preparation, showing collagen fibers (red) and a network of thin elastin fibers (black), with interspersed oval gray nuclei, mainly of fibroblasts.
