It has less ground substance than loose connective tissue. Dense regular elastic tissue contains elastin fibers in addition to collagen fibers, which allows the ligament to return to its original length after stretching. It is made primarily of parallel collagen fibers, a few elastic fibers and the major cell type is the fibroblast. Dense regular elastic tissue contains elastic fibers in addition to collagen fibers. In many sources, this type is listed as connective tissue proper; however, … * The American Council on Education's College Credit Recommendation Service (ACE Credit®) has evaluated and recommended college credit for 33 of Sophia’s online courses. To understand why connective tissue is so important, lets take a close look at the various kinds of connective tissue, along with some examples. blood tissue types. Mostly these types of connective tissues are found in tendons and ligaments. This one will cover the more densely arranged types of connective tissue proper called: dense irregular, dense regular, and dense elastic. Dense irregular CT is used to form the capsules that surround our internal organs such as the pericardium or the renal capsule. Objectives •Describe each type of connective tissue (CT) and explain where they are found. The last two packets (areolar & reticular, adipose) covered the loosely arranged types of connective tissue proper. 46 (Tendon) Elastic connective tissue (Human aorta c.s.) Dense regular connective tissue establishes a connection between different tissues that are present in the human body. The collagen fibers are stacked on one another in a neat parallel array. Dense regular connective tissue is composed of fibroblasts that excrete high amounts of collagen fibers. Blood It is liquid connective tissue which comprises of blood plasma and formed elements such as red blood cells, white blood cells and platelets. Use these modules to answer the following questions. Its collagen bundles are all oriented in parallel and the fibroblasts are also dispersed in rows between the collagen. Dense packing od component fibers maximum strength to this tissue. Fibrocartilage. Ligaments and tendons are made of dense regular connective tissue, but in ligaments not all fibers are parallel. Hyaline cartilage. (thin-section) Dense regular connective tissue is mainly made up of type I collagen fibers. Look at this image and make sure you can recognise loose and dense connective tissue. Arteries need this tissue within its walls because of the high pressure and velocity of the blood flowing through them. Some applications require a ligament to balance tensile strength and elasticity, and thus contain elastic fibers in addition to collagen fibers that allow the ligament to return to its original length after stretching. It forms structures like tendons in which the forces are directed in a single direction. Ligaments and tendons are made of dense regular connective tissue. It is also be present in numerous of the ligaments in the body. © 2021 SOPHIA Learning, LLC. The human body is full of various types of connective tissue, the function of which is to bind together the other tissue of the body and give those tissues support. Dense regular connective tissue, found in structures such as tendons and ligaments , is characterized by collagen fibers arranged in an orderly parallel fashion, giving it tensile strength in one direction. The three types of dense connective tissue are regular, irregular, and elastic tissue. Answer: 1. hyaline, elastic, fibrocartilage. Dense regular connective tissue is a collagenous connective tissue designed to be incredibly strong in one direction. Elastic connective tissue is the only specimen that contains significant amounts of elastic fibers. This tissue allows for the arteries to expand under high pressure and recoild under low pressure which is important for promoting smooth blood flow. We gratefully acknowledge the assistance of those who contributed to the completion of this project. a. compact and spongy. These capsules are important for protecting the organs and for preventing leakage into or out of the organ. Dense regular connective tissue is a collagenous connective tissue designed to be incredibly strong in one direction. Dense irregular connective tissue consists of mostly collagen fibers. Connective tissue connects, separates & supports all other types of tissues in the body, it consists of cells surrounded by a compartment of fluid called the extracellular matrix (ECM). SOPHIA is a registered trademark of SOPHIA Learning, LLC. Elastic connective tissue is a specialized type of dense connective tissue with a much higher proportion of elastic fibers. The unorganized array of collagen allows this tissue to conform to the exact shape of the organ. Adipose connective tissues are large fat located underneath the skin. Dense regular connective tissue is also known as Regular Fibrous Connective Tissue and it is a type of general connective tissues consisting of type I collagen bundles that are arranged according to a definite pattern in which the fibers and fibroblasts align parallel to prolonged resistant forces that are exerted in the same direction. Common examples of connective tissues include tendons, adipose tissue, and cartilage. Reticular connective tissue. It is dense regular connective tissue with both collagen and elastic … dense regular connective tissue is composed of collagen fibers that are arranged parallel in the form of a bundle. •Relate the functions of each connective tissue to their structural organization. It is also of two types: white fibrous connective tissue and yellow elastic connective tissue. Dense elastic CT is found in the large arteries of the body; the aorta would be the largest example. dense connective tissue types. Due to its rubbery nature, elastic tissue can recoil after stretching . Dense irregular connective tissue (Silver stain) Dense regular connective tissue (Dense fibrous c.t.) Dense connective tissue is divided into 1) dense regular, 2) dense irregular, 3) elastic. This packet goes over the three types of dense connective tissue propers (regular, irregular, elastic). The collagen fibers travel in all directions which is vital to this tissue's function. Dense irregular connective tissue has fibers that are not arranged in parallel bundles as in dense regular connective tissue. Many different colleges and universities consider ACE CREDIT recommendations in determining the applicability to their course and degree programs. Dense regular connective tissue contains white structures with great resistance to _____. In dense irregular connective tissue, the direction of fibers is random. Dense regular connective tissue fibers are parallel to each other, enhancing tensile strength and resistance to stretching in the direction of the fiber orientations. 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. blood and lymph. It is thicker and stronger than loose connective tissue and forms a protective capsule layer around organs such as the liver and kidneys. This type of tissue contains a dense woven network of collagenous (and some elastic) fibres in a viscous matrix. It is impact resistant. The collagenous fibers are irregularly arranged in interwoven sheets that makes the tissue very strong. Dense irregular connective tissue, which is made up of elastic fibers and a type of protein fiber called collagen, provides protection to the tissues or organs it surrounds. By the time you are finished with this packet you should be able to differentiate between them based on their apperance and know their functions. •List the types of cells, fibers, and other extracellular matrix components found in connective tissues. Dense Irregular and Elastic Connective Tissue Summary, http://www.udel.edu/biology/Wags/histopage/colorpage/colorpage.htm. Areolar connective tissue. Dense connective tissue is dense because of the high proportion of fibers that run parallel to each other. Supports the body 3. This section of dense regular collagenous tissue is from the tendon of a skeletal muscle. Figure 4: Dense regular tissue. Provides protection 4. The dense regular connective tissue is further classified into two varieties: dense regular collagenous connective tissue and dense regular elastic connective tissue. Moreover, elastic cartilage is a type of cartilage while elastic connective tissue is a type of dense connective tissue. Dense Regular Connective Tissue Dense routine connective tissue is identified by an abundance of securely loaded collagen fibers and fairly couple of cells The collagen fibers exist in big packages that are “frequently” set up, indicating they are normally parallel to each other. Module 4.10 Types of Dense Connective Tissue, using the dots under the image to examine a series of histology micrographs and learn about how the structure of dense regular connective tissue and dense irregular connective tissue facilitates their functions. The ligamentum nuchae is a ligament at the back of the neck. Sophia partners Institutions have accepted or given pre-approval for credit transfer. Adipose connective tissue. Dense irregular connective tissue (Figure 5) is composed of haphazardly arranged, densely packed collagen bundles with many purple stained fibroblasts present. 299 The dense regular connective tissue is composed of collagen fibers that are arranged parallel in the form of a bundle. credit transfer. This strong tissue is typically found in the tendons of muscles. Dense irregular connective tissue also contains fibroblasts and collage but differs in its arrangement. As we age the fibers within start to cross-link which makes the arteries more stiff and tight whihc winds up causing elevated blood pressure (hypertension). This one will cover the more densely arranged types of connective tissue proper called: dense irregular, dense regular, and dense elastic. Its collagen bundles are all oriented in parallel and the fibroblasts are also dispersed in rows between the collagen. *No strings attached. The collagen fibers are densely packed together and arranged in parallel to each other. Dense regular connective tissue is found in tendons and ligaments. From: Douglas P. Dohrman and TAMHSC Faculty 2012 Structure and Function of Human Organ Systems, Histology The main difference between elastic cartilage and elastic connective tissue is that the elastic cartilage contains a polysaccharide called chondroitin sulfate whereas the elastic connective tissue does not contain chondroitin sulfates. dense regular elastic connective… 1. Dense regular: Tendons and ligaments are examples of dense regular connective tissue.
