Due to its rubbery nature, elastic tissue can recoil after stretching . Dense regular connective tissue is composed of fibroblasts that excrete high amounts of collagen fibers. It is impact resistant. From: Douglas P. Dohrman and TAMHSC Faculty 2012 Structure and Function of Human Organ Systems, Histology *No strings attached. Elastic connective tissue is the only specimen that contains significant amounts of elastic fibers. Dense irregular connective tissue has fibers that are not arranged in parallel bundles as in dense regular connective tissue. * 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. The collagen fibers are stacked on one another in a neat parallel array. The dense regular connective tissue is composed of collagen fibers that are arranged parallel in the form of a bundle. (A) Dense Regular Connective Tissue: In the dense regular connective tissue, the collagen fibres are present in rows between many parallel bundles of fibres. This one will cover the more densely arranged types of connective tissue proper called: dense irregular, dense regular, and dense elastic. The ligamentum nuchae is a ligament at the back of the neck. 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. (Tendon) Elastic connective tissue (Human aorta c.s.) Binds body tissues together 2. Reticular connective tissue. regular, irregular (sometimes elastic) cartilage tissue types. Its collagen bundles are all oriented in parallel and the fibroblasts are also dispersed in rows between the collagen. The ligaments in the vocal folds and between the vertebrae in the vertebral column are elastic. Dense regular connective tissue attaches muscle to bone and with the cells organized in one direction so that it pulls in one direction, like a tendon that connects to the bicep. In this variety of dense connective tissue, the fibers are densely packed and are arranged parallel to each other. Adipose connective tissues are large fat located underneath the skin. Figure 4: Dense regular tissue. Answer: 1. Dense regular connective tissue is mainly made up of type I collagen fibers. It is also of two types: white fibrous connective tissue and yellow elastic connective tissue. Dense regular elastic tissue contains elastic fibers in addition to collagen fibers. Mostly these types of connective tissues are found in tendons and ligaments. The collagen fibers are densely packed together and arranged in parallel to each other. Dense regular connective tissue is a collagenous connective tissue designed to be incredibly strong in one direction. Supports the body 3. Dense regular connective tissue fibers are parallel to each other, enhancing tensile strength and resistance to stretching in the direction of the fiber orientations. Dense connective tissue is dense because of the high proportion of fibers that run parallel to each other. Blood It is liquid connective tissue which comprises of blood plasma and formed elements such as red blood cells, white blood cells and platelets. •List the types of cells, fibers, and other extracellular matrix components found in connective tissues. Dense regular connective tissue contains white structures with great resistance to _____. Dense irregular connective tissue (Figure 5) is composed of haphazardly arranged, densely packed collagen bundles with many purple stained fibroblasts present. Areolar Connective Tissue These tissues are widely distributed and serve as a universal packing material between other tissues. The collagenous fibers are irregularly arranged in interwoven sheets that makes the tissue very strong. dense regular connective tissue is composed of collagen fibers that are arranged parallel in the form of a bundle. 1. 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). Image Source: austincc.edu. dense regular collagenous connective tissue?c. bone tissue types. (thin-section) Areolar connective tissue. Dense regular connective tissue is composed of fibroblasts that excrete high amounts of collagen fibers. The unorganized array of collagen allows this tissue to conform to the exact shape of the organ. Fibrocartilage. The dense regular connective tissue contains parallelly arranged collagen fibers in a single direction. The last two packets (areolar & reticular, adipose) covered the loosely arranged types of connective tissue proper. dense connective tissue types. 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. In dense irregular connective tissue, the direction of fibers is random. This strong tissue is typically found in the tendons of muscles. Dense packing od component fibers maximum strength to this tissue. Connective tissue is the most common kind of tissue out of all of the primary kinds of tissue (epithelial, muscular, connective, a… 299 There are three major categories of dense connective tissue: regular, irregular, and elastic. Dense irregular CT is used to form the capsules that surround our internal organs such as the pericardium or the renal capsule. Use these modules to answer the following questions. Elastic connective tissue is a specialized type of dense connective tissue with a much higher proportion of elastic fibers. Dense regular elastic tissue contains elastin fibers in addition to collagen fibers, which allows the ligament to return to its original length after stretching. Ligaments and tendons are made of dense regular connective tissue. Dense irregular connective tissue (Silver stain) Dense regular connective tissue (Dense fibrous c.t.) Hyaline cartilage. This video will cover the three types of dense connective tissue proper: regular, irregular and elastic, Source: Self made with images from Marieb & http://www.udel.edu/biology/Wags/histopage/colorpage/colorpage.htm, Here are some images for you to study, pay attention to the arrangement of the fibers, Source: self made with images from http://www.udel.edu/biology/Wags/histopage/colorpage/colorpage.htm. •Relate the functions of each connective tissue to their structural organization. This type of tissue is what forms the tendons and ligaments of the human body. Provides protection 4. This makes it the ideal tissue to line the walls of the bronchiole tubes so that the lungs can deflate after inhaling and to line the walls of large arteries so that these vessels can pulse blood through the body. Loose connective tissue has much more ground substance and a relative lack of fibrous tissue, while the reverse is true of dense connective tissue. This section of dense regular collagenous tissue is from the tendon of a skeletal muscle. This college course is 100% free and is worth 1 semester credit. It is found in joint capsules, in the connective tissue that envelops muscles (muscle fascia), and it forms dermis of skin.
