Dense connective tissue, is one of the types of connective tissue also referred to as dense fibrous tissue due to relative abundance of the collagen fibers. Among the four main basic types of animal tissues, connective tissue is one of the major types present. Dense regular connective tissue is composed of three main components: fiber producing cells, fibers, and an extracellular fluid matrix. It also contains fewer cells and less ground substance in comparison with the other type, loose connective tissue. It is customary to describe dense conective tissue as "irregular" or "regular". Dense irregular: Much of the dermis layer of the skin is composed of dense irregular connective tissue. In many sources, this type is listed as connective tissue proper; … Fibroblasts are usually the most numerous cells in both forms of connective tissue. All connective tissue has an extracellular matrix of proteins, water, and carbohydrate molecules that forms something called ground substance. Collagen fibers are very thick wide fibers that provide the tissue with a high degree of stretch (due to the undulating pattern of fibers that can stretch straight) and a very high level of tensile strength, meaning that they can resist tearing when the fibers are pulled on length-wise. B. bone, cartilage, glands, and adipose tissue. Among the collagen fibers there is a network of elastic fibers as well, to limit the distensibility of the tissue. This creates a tissue that has tensile strength in all directions. Aponeuroses are important in attaching bone to muscle. Key Difference – Dense Regular vs Dense Irregular Connective Tissue.
