Bone, compact, ground, cs. Ligaments and tendons are made of dense regular connective tissue. - know what the three types of dense CT are (regular, irregular, elastic), - know that the main protein in the ECM is collagen, - know the visible differences between dense regular and irregular CT, - know that these tissues are populated by fibroblasts, - know where you find dense regular CT and its functions, - know where you find dense irregular CT and its functions, - know where you find dense elastic CT and its functions. 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. Dense connective tissue is dense because of the high proportion of fibers that run parallel to each other. •List the types of cells, fibers, and other extracellular matrix components found in connective tissues. The three types of dense connective tissue are regular, irregular, and elastic tissue. 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). Histology - Dense regular connective tissue. Dense regular connective tissue establishes a connection between different tissues that are present in the human body. Dense regular connective tissue contains white structures with great resistance to _____. Dense irregular CT is used to form the capsules that surround our internal organs such as the pericardium or the renal capsule. dense connective tissue types. Dense irregular connective tissue also contains fibroblasts and collage but differs in its arrangement. This type of tissue contains a dense woven network of collagenous (and some elastic) fibres in a viscous matrix. 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. The collagenous fibers are irregularly arranged in interwoven sheets that makes the tissue very strong. It is also of two types: white fibrous connective tissue and yellow elastic connective tissue. It forms structures like tendons in which the forces are directed in a single direction. The connective tissue is the glue that holds all other tissues together, it has the important function of ensuring that our body systems work in harmony. Areolar Connective Tissue These tissues are widely distributed and serve as a universal packing material between other tissues. Sophia partners In dense irregular connective tissue, the direction of fibers is random. However, not all connections are by dense regular connective tissues. The collagen fibers are densely packed together and arranged in parallel to each other. In many sources, this type is listed as connective tissue proper; however, … 1. The dense regular connective tissue contains parallelly arranged collagen fibers in a single direction. It is dense regular connective tissue with both collagen and elastic … 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. Adipose connective tissues are large fat located underneath the skin. The dense regular connective tissue is further classified into two varieties: dense regular collagenous connective tissue and dense regular elastic connective tissue. Answer: 1. To understand why connective tissue is so important, lets take a close look at the various kinds of connective tissue, along with some examples. Adipose connective tissue. Fibroblasts lie in rows between the collagen packages. Areolar connective tissue. 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. The collagen fibers are stacked on one another in a neat parallel array. It is also be present in numerous of the ligaments in the body. 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. Dense regular elastic tissue contains elastic fibers in addition to collagen fibers. (A) Dense Regular Connective Tissue: In the dense regular connective tissue, the collagen fibres are present in rows between many parallel bundles of fibres. Arteries need this tissue within its walls because of the high pressure and velocity of the blood flowing through them. regular, irregular (sometimes elastic) cartilage tissue types. Dense packing od component fibers maximum strength to this tissue. Dense elastic CT is found in the large arteries of the body; the aorta would be the largest example. This strong tissue is typically found in the tendons of muscles. Ligaments and tendons are made of dense regular connective tissue, but in ligaments not all fibers are parallel. Dense regular connective tissue fibers are parallel to each other, enhancing tensile strength and resistance to stretching in the direction of the fiber orientations. © 2021 SOPHIA Learning, LLC.
