Degree in Plant Science, M.Sc. There are seven types of connective tissues found in the body of people. Dense connective tissue is often further divided into two main categories; dense irregular connective tissue and dense regular connective tissue. In dense irregular connective tissue, the direction of fibers is random. Dense irregular connective tissue is another type of connective tissues in which collagen fibers are arranged irregularly. Dense regular connective tissue has dark staining collagen fibers. <>>> Both tissues establish connections between different tissues. Both these types could be further divided and arranged according to two aspects; cord arrangement and sheet arrangement. It could be classified into two sub types of connective tissues namely; dense regular white fibrous connective tissue and dense regular yellow fibrous connective tissue. It forms structures like tendons in which the forces are directed in a single direction. Similarities Between Dense Regular and Dense Irregular Connective Tissue The collagen fibers … FALSE; possess a large quantity of reticular fibers The basic difference between dense irregular and dense regular connective tissues is in the amount of elastic fibers and adipose cells present. Dense regular connective tissue fibers are parallel to each other, enhancing tensile strength and resistance to stretching in the direction of the fiber orientations. 6. In cord arrangement, the collagen bundles and matrix are arranged in regular alternate patterns. This one will cover the more densely arranged types of connective tissue proper called: dense irregular, dense regular, and dense elastic. Connective Tissue Definition. Difference between Dense regular and irregular connective tissue.
