Collagen fibers Nuclei of fibroblasts Fibrous joint capsule Figure 4.8f (f) Connective tissue proper: dense connective tissue, elastic Description: Dense regular connective tissue containing a high proportion of elastic fibers. Collagen fibers are very thick wide fibers that provide the tissue with a high degree of stretch (due to the undulating pattern of fibers that can stretch straight) and a very high level of tensile strength, meaning that they can resist tearing when the fibers are pulled on length-wise. Tendons and ligaments attach to bones, and the role of dense regular connective tissue is to transfer forces to bones. Dense regular connective tissue comprises structures such as ligaments and tendons, whilst dense irregular tissue is more widely distributed throughout the body. Elastin fibers are the other type of fiber found in dense regular connective tissue. Select a subject to preview related courses: The proportions of these two fibers vary based on the elastic needs of the location where dense regular connective tissue is found. Ligaments need to be strong as they connect bones together, and hold joints in place. Dense connective tissue is often further divided into two main categories; dense irregular connective tissue and dense regular connective tissue. The major cell type is fibroblast. It's actually these fibers that give this connective tissue its name; collagen fibers are densely packed and arranged in a parallel, undulating, regular pattern - hence, dense regular connective tissue. Dense connective tissue A. Irregular connective tissue consist mainly of elastin fibers B. - Structure, Uses & Benefits, Quiz & Worksheet - Dense Regular Connective Tissue, Over 83,000 lessons in all major subjects, {{courseNav.course.mDynamicIntFields.lessonCount}}, Middle School Life Science: Homework Help Resource, Biological and Biomedical Loose connective tissue is the most abundant type. These are basically dense masses of collagenic fibers and fibroblasts arranged in an orderly manner, with the cells and fibers being oriented in the same direction (i.e. What Can You Do With a Master's in Psychology? Learning anatomy is a massive undertaking, and we're here to help you pass with flying colours. The 3-dimensional nature of dense irregular connective tissue gives it a great deal of strength. Three stranded collagen molecules are packed together to form collagen fibrils and their alignment yield characteristic ultrastructural striations. Ligaments form from thick bundles of connective tissue, mainly forming from collagen. This is a section of collagenous connective tissue from the reticular layer of the dermis. The dominant fiber type in dense connective tissue is what? Fibroblasts are usually the most numerous cells in dense connective tissue. 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. Services. How Long Does IT Take To Get A PhD IN Nursing? imaginable degree, area of Dense Regular Connective Tissue. You're probably most familiar with dense regular connective tissue in the form of your tendons (tissue that connects muscle to bone) and ligaments (tissue that connects bone to bone). Log in here for access. Now, the amount of ground substance that each type of connective tissue has varies based on the amount of space that needs to be filled between the fibers. Uruj Zehra MBBS, MPhil, PhD Location: As stated earlier, the areolar tissue is the most widely distributed connective tissue in the body. They can resist extreme pulling and stretching forces along the length of their fibers while still remaining highly pliable and flexible. succeed. Elastin fibers work like elastic bands. Key Difference – Dense Regular vs Dense Irregular Connective Tissue. Connective tissue, group of tissues in the body that maintain the form of the body and its organs and provide cohesion and internal support. This strong tissue is typically found in the tendons of muscles. just create an account. Collagen fibers are tough, thick fibrous proteins found in dense connective tissues. A small amount of ground substance is present around dense regular connective tissue fibers and cells. You can also find them around the bone’s fibrous sheath. Collagen fibers have good tensile strength and are therefore important in support. Methods of preparation-and use of dense regular connective tissue xenografts from non- human animals to repair and/or replace corresponding damaged human tissue are described. This unique property allows them to transit mechanical force over long distances using a minimum of material and space, while resisting mechanical forces from other directions. In some muscles, the bone attachment is only partially aponeurotic, and partially tendinous, but in some cases, the bone attachment is entirely aponeurotic. Introduction to the musculoskeletal system. It can be found in a number of locations within the body, including the dermis of the skin, in glandular tissue, in the walls of organs, and in the whites of the eyes. The connective tissues include several types of fibrous tissue that vary only in their density and cellularity, as well as the more specialized and recognizable variants— bone , ligaments , tendons , cartilage , and adipose (fat) tissue. In many sources, this type is listed as connective tissue proper; … It also contains fewer cells and less ground substance in comparison with the other type, loose connective tissue. It has less ground substance than loose connective tissue. It is found in areas of the body where large amounts of tensile strength are required, like in ligaments, tendons and aponeurosis. Dense regular connective tissue is an extremely strong tissue type that can resist a great deal of force along the length of their fibers while still remaining extremely flexible. Your strength is actually the product of your muscles along with the dense regular connective tissue of your tendons. Dense regular: Tendons and ligaments are examples of dense regular connective tissue. The type I collagen fibers of the dense irregular connective tissue are surrounded by small amounts of ground substance. In general, fibroblasts become very active during wound repair and healing process, when they proliferate and form fibrous matrix. Create an account to start this course today. Description: Primarily irregularly arranged collagen fibers. Specialized connective tissue comes in surprising forms. This makes them very strong and resistant to stretch. Fibroblasts are usually the most numerous cells in both forms of connective tissue. ), Working Scholars® Bringing Tuition-Free College to the Community, Loose (which are 'loosely' packed tissues that appear to have spaces). Dense connective tissue, is one of the types of connective tissue also referred to as dense fibrous tissue due to relative abundance of the collagen fibers. Therefore, connective tissue with densely packed fibers, like dense regular connective tissue, has much less ground substance than those with loosely packed fibers. | {{course.flashcardSetCount}} Dense connective tissue is dense because of the high proportion of fibers that run parallel to each other. Meanwhile, aponeuroses are flat sheets of collagen fibers that normally comprise numerous layers. Description of matrix, fibres and cells has already been given in the general structure of connective tissue. They have large euchromatic nuclei with prominent nucleoli.

Collagen and elastin are added to many beauty products. An error occurred trying to load this video. Without your tendons, your muscles would easily detach when you moved or flexed because muscles, while being strong fibers, aren't particularly great attachment tissues. [1] Tendons, which connect muscle to bone, derive their strength from the regular, longitudinal arrangement of bundles of elastic fibers. This group includes related tissues that form our tendons, body fat, bones, and cartilage. As a consequence, it displays greater resistance to stretching. The myofibroblasts are characterized by the presence of actin filaments and dense bodies. What are some pros and cons about beauty products and their effects on human tissues? Tendons are generally resistant to extension, but flexible, meaning that they can be easily distorted around bones and joints. Fibroblast cells are fiber-producing cells whose role it is to repair and produce the collagen and elastin fibers of the tissue. Ground substance, is very flexible and can take the shape of anything, but when it sets, it is firm while still remaining pliable.
