Their main function is to support and transmit mechanical forces. Dense regular connective tissue is composed of fibroblasts that excrete high amounts of collagen fibers. Dense connective tissue is divided into 1) dense regular, 2) dense irregular, 3) elastic. Look at this image and make sure you can recognise loose and dense connective tissue. The fibers occur in bundles that may have no preferential arrangement, as in dense irregular connective tissue (e.g. It is found in joint capsules, in the connective tissue that envelops muscles (muscle fascia), and it forms dermis of skin. In many sources, this type is listed as connective tissue proper; however, it is … It is dense regular connective tissue with both collagen and elastic fibers. tendons, ligaments, aponeuroses). Dense connective tissue can be further classified into dense regular connective tissue and dense irregular connective tissue. Objectives •Describe each type of connective tissue (CT) and explain where they are found. Areolar Connective Tissue. The structure and function of several main cell types in connective tissue (fibroblast, macrophage, plasma cell, mast cell, fat cell and mesenchymal cell). It supports the internal framework of organs such as liver, lymph nodes and spleen. c. Dense regular connective tissue d. Dense irregular connective tissue e. None of the above 10. It has both collagen and elastic fibers, which provide great tensile strength and elasticity in one direction. Dense irregular connective tissue in which collagen and elastic fibers are found running in all different directions and planes. Loose connective tissue is the most abundant type. When a connective tissue has a high concentration of cells or fibers, it has a proportionally-less-dense matrix. Elastic connective tissue, as the name implies, helps the body maintain homeostasis by regulating blood pressure and helping the body exhale normally. Dense regular elastic tissue contains elastin fibers in addition to collagen fibers, which allows the ligament to return to its original length after stretching. From: Douglas P. Dohrman and TAMHSC Faculty 2012 Structure and Function of Human Organ Systems, Histology In addition, they perform the work of connecting the body tissue, cell, and organs. 2. Types of Connective Tissues. The functions of areolar connective tissue include the support and binding of other tissues. Fibers are densely packed and organized in parallel to create a strong tissue capable of withstanding the pull of muscle and bone in movement. Connective Tissue Definition. There are seven types of connective tissues found in the body of people. Dense elastic connective tissue has abundant elastic fibersamong its collagen fibers. The elastic modulus of ligament is about 150–355 MPa, and the tensile strength is less than 50 MPa. Dense regular connective tissue (Figure 4) has fibers arranged in neatly organized, parallel bundles. Loose irregular connective tissue contains numerous cells and a loose fiber arrangement in a moderately viscous fluid matrix. Elastic connective tissue is a modified dense connective tissue that contains numerous elastic fibres in addition to collagen fibres which allows the tissue to return to its original length after stretching. Doctor insights on: Dense Elastic Connective Tissue Share Share Follow @HealthTap Embed Dr. Ronald Krauser Dr. Krauser 1 1 Joints such as elbow, shouldeer and knee contains considerable amount of cartilage and dense connective tissue. Collagen, Elastic and sometimes reticular. Elastic Connective Tissue - the ligamentum nuchae is an example of elastic connective tissue. Whereas, dense connective tissue is less abundant, and it consists of many fibres in the matrix. Learn vocabulary, terms, and more with flashcards, games, and other study tools. 1. Start studying Connective Tissue. Key Difference – Dense Regular vs Dense Irregular Connective Tissue. a. Hyaline cartilage b. Elastic cartilage c. Dense regular connective tissue d. Dense irregular connective tissue e. None of the above 11. Reticular Connective Tissue: It is made up of reticular fibres. Ligaments are dense connective tissues constituted by a protein phase (collagen and elastin) and a polysaccharide phase (proteoglycans). This type of tissue has a high amount of elastic fibers. This type of tissue contains a dense woven network of collagenous (and some elastic) fibres in a viscous matrix. Dense regular connective tissue makes up tendons and ligaments. These tissues are widely distributed and serve as a universal packing material between other tissues. Elastic fibers (ls) These images compare dense irregular connective tissue stained by the Verhoeff method (left) and the Movat pentachrome stain (right); in both stains, elastic fibers appear black. Dense regular elastic tissue contains elastin fibers in addition to collagen fibers, which allows the ligament to return to its original length after stretching. These are: Areolar Connective Tissue; Adipose Tissue; Dense Irregular Tissue MTY1102- CHAPTER 4- LECTURE OUTLINE • Dense elastic connective tissue has abundant elastic fibers among its collagen fibers. Dense connective tissue is dense because of the high proportion of fibers that run parallel to each other. Dense Regular Connective Tissue Dense White Fibrous CT Connective Tissue Lots of collagen fibers, all running in the same direction lending it strength Function: Connects structures that need a strong bond Found tendons ligaments organ capsules dermis. Dense connective tissue is found in joint capsules, muscle fascia, and the dermis layer of skin. Connective tissue proper: Elastic connective tissue: function Allows recoil of tissue following stretching; maintains a pulsatile flow of blood through arteries; aids passive recoil of lungs following inspiration. (A) Dense Regular Connective Tissue: In the dense regular connective tissue, the collagen fibres are present in rows between many parallel bundles of fibres. In dense irregular connective tissue, the … It is also of two types: white fibrous connective tissue and yellow elastic connective tissue. ... Elastic Connective Tissue. ...
