Therefore, since some areas need more stretch than others, there are actually two subclasses of dense regular connective tissue: white connective tissue (or dense collagen connective tissue), which is mostly collagen fibers and appears white (hence the name); and yellow connective tissue (or dense elastin connective tissue), which is mostly elastin fibers and appears yellow. Dense regular connective tissue is an extremely important type of connective tissue that provides the structures that they bind and/or encase a great deal of … The old and inactive fibroblasts, also known as fibrocytes have reduced cytoplasm with few cell organelles and flattened heterochromatic nuclei. Collagen and elastin are added to many beauty products. Three stranded collagen molecules are packed together to form collagen fibrils and their alignment yield characteristic ultrastructural striations. Saved by Micky Sclama. Dense regular connective tissues primarily contain collagen fibres in rows between many parallel bundles of tissues and a few elastic fibres. Connective tissue, group of tissues in the body that maintain the form of the body and its organs and provide cohesion and internal support. Function: Withstands tension. They are present close to the collagen fibers and appear as flattened, fusiform or spindle shaped cells. Therefore, connective tissue with densely packed fibers, like dense regular connective tissue, has much less ground substance than those with loosely packed fibers. Ground substance is amorphous and gel-like in texture that surrounds cells. This layer is characterized by thick bundles of collagen that are organized in various directions within the tissue.
