Collagen gives strength and flexibility to issues and holds them in place. Ligaments attach two bones together. They are loose connective tissues and dense or fibrous connective tissues. (1, 2). Introduction to Connective Tissue Disorders in Children. Dense irregular connective tissue is found in high concentrations in body parts where support is needed to prevent the effects of forces that pull in multiple directions. Picture 7: Human cartilage connective tissues’ functions are primarily centered on the bones, especially protecting the bones and enabling movements. The irregular arrangement gives uniform strength in all directions. ... For example, they support and separate the organs in the abdominal cavity, while allowing distribution between them of vascular and nervous structures . eg: areolar, adipose, reticular. Dense irregular tissue: There are many fibres including collagen, which are oriented irregularly or randomly. In dense irregular connective tissue, collagen fibers are arranged irregularly as the name itself suggests. Figure 4.9. Connective tissues are the most abundant tissues in the body. Examples of dense regular tissue are tendons and ligaments. Dense Connective Tissue. The human body consists of different types of tissues namely the nervous, muscular, epithelial, and connective tissues. The second category includes those where the connective tissue is the target of antibodies directed against it. See also: connective tissue. Among these, tendons and ligament are the examples of dense regular connective tissue, which is made up of 3 components: fiber producing cells or fibroblast cells, fibers, and an extracellular fluid matrix. Figure 4. Navallas M, Inarejos clemente EJ, Iglesias E, Rebollo-polo M, Antón J, Navarro OM. Dense connective tissue forms strong, rope-like structures such as tendons and ligaments. a. Hyaline cartilage b. Elastic cartilage c. Dense regular connective tissue d. Dense irregular connective tissue e. None of the above 11. Heritable Disorders of Connective Tissue. Dense irregular connective tissue (dict) is found in several places in the body. Dense irregular connective tissue has many fibers but these are not structured as with regular tissue types. For example, if a tissue has more elastin it will be stretchy. Image Source: austincc.edu. Dense elastic tissue allows tissue to stretch and recoil. There are three primary types of connective tissues and these are the proper connective tissues, supporting connective tissues, and fluid or liquid connective tissues. Elastin is a stretchy protein that resembles a rubber band and is the major component of ligaments and skin. They may be inherited, caused by environmental factors, or most often, are of unknown cause. Muscle tissue mainly facilitates body movements and locomotion. (B) Dense Irregular Connective Tissue: It has fibroblasts and many fibres (mostly collagen) that are oriented differently. Dense irregular elastic tissues give arterial walls the strength and the ability to regain original shape after stretching (Figure 4.9). dense irregular connective tissues _____ is found in the dermis, fibrous joint capsules, and fibrous coverings of some organs some ligaments are very elastic for example, ligaments connecting_______ must be very elastic Connective Tissue Disorders in Childhood: Are They All the Same? There are several types of connective tissue disease. Murali, Mandakolathur R.Autoimmune Disorders Involving the Connective Tissue and Immunodeficiency Diseases. Fibers are seen sectioned longitudinally (ls) and transversly (xs). Little ground substance is present. The collagenous fibers are irregularly arranged in interwoven sheets that makes the tissue very strong. The abundance of collagenous fibres gives the tissue strength. It varies in types and distributed in various parts of the body. Some of the diseases, like the ones mentioned above, can cause serious pulmonary issues. Maintaining the collagen and hyaluronic acid levels in body is the key to beautiful, wrinkle free skin and healthy, flexible pain free joints, tendons and discs. The majority of cells are fibroblasts. Fibroblasts are scarce and usually the only cell type present. Every part is connected to other parts. Picture 8: A closer look at bone connective tissues. Cleveland Clinic is a non-profit academic medical center. Loose (areolar) connective tissue Loose (areolar) CT is characterized by relatively loosely arranged collagen and elastic fibers.
