They are much thinner than collagen fibers, and they allow a higher degree of stretch than collagen alone. credit by exam that is accepted by over 1,500 colleges and universities. It is found in areas of the body where large amounts of tensile strength are required, like in ligaments, tendons and aponeurosis. Dense irregular connective tissue also forms joint capsules and the fibrous coverings of kidneys, cartilages, and nerves. credit-by-exam regardless of age or education level. To unlock this lesson you must be a Study.com Member. Blood vessels, both large and small, course through connective tissue, which is therefore closely associated with the nourishment of tissues and organs throughout the body. Dense regular connective tissue. You can also find them around the bone’s fibrous sheath. These structures help attach muscles to bones and link bones together at joints. Tissue Function: The role of dense regular connective tissue is to transfer forces to bones. These fibrous tissues form your tendons, ligaments, and fibrous membrane coverings. As a consequence, it displays greater resistance to stretching. All other trademarks and copyrights are the property of their respective owners. Within the category of connective tissue there are six types: Here, we are going to explore one of the fibrous types known as dense regular connective tissue. Resources for District, State & National Education Standards, Tech and Engineering - Questions & Answers, Health and Medicine - Questions & Answers. Collagen fibers are one of two types of fibers that compose the majority of the tissue. This type of body tissue makes up the dermis — the leathery second layer of the skin. Dense regular connective tissue gets its name from its densely packed collagen fibers that fit snugly together in a regular and consistent undulating pattern. Muscle is attached to the bones it moves by tendons, thick lengths of connective tissue that pull on the bones like rope. Function of connective tissue: It binds various tissue together like skin with the muscles and muscles with bones; It form inter cellular substance between cells of different types of tissue, so that help in friction less movement of the body organ; It forms sheaths around the body organs and make a kind of packaging tissue; The areolar tissue protects the body against wound and infection Dense regular connective tissue (DRCT) is divided into white fibrous connective tissue and yellow fibrous connective tissue, both of which occur in two forms: cord arrangement and sheath arrangement. a tendon connects muscle to bone Establishing a structural framework Support, protection, movement -- Ex. Attach muscle to bones and bones to each other. Fascia, the outer wrapping that binds together groups of muscles, blood vessels, and nerves, is also composed of dense regular connective tissue. d) Pseudo stratified columnar epithelial tissue. The functions of areolar connective tissue include the support and binding of other tissues. A tendon serves to move the bone or structure. The connective tissue proper possesses a soft, gel-like matrix, less rigid and shows a varying degree of toughness The connective tissue proper is generally subdivided on the basis of morphological characteristics in the following types of tissues 1. The tissue provides support to the body’s first line of defense. Collagen type I fibrils are described as long crystals that are arranged in an anisotropic fashion [1–8].These collagen fibrils are organized into primary, secondary, and tertiary bundles, responsible for the mechanical resilience of the tissue (Table 1). Fats/bones Dense connective tissue, also called dense fibrous tissue, forms the body’s tendons, ligaments, joint capsules, and aponeuroses, as well as the dermis of the skin. This video explains how dense connective tissue differs from loose connective tissue.

Dense connective tissue is dense because of the high proportion of fibers that run parallel to each other. Organ Function: Attaches muscle to bone. Introduction . Bone. hyaline, elastic, fibrocartilage formed by chondroblasts and chondrocytes Matrix = collagen and elastin Gelatinous ground substance. Section 2 of the basic science (Tr & Orth) syllabus is a large topic, difficult to grasp at face value as it appears quite removed from the average orthopaedic surgeon’s practice. Like all connective tissue, dense regular connective tissue is composed of cells, in this case fibroblast cells (fiber producing cells), fibers (elastin and collagen), as well as a jelly-like extracellular matrix called ground substance. Ground substance, is very flexible and can take the shape of anything, but when it sets, it is firm while still remaining pliable. Another type of connective tissue is dense or fibrous connective tissue, which can be found in tendons and ligaments. Connective Tissue Definition. Therefore, connective tissue with densely packed fibers, like dense regular connective tissue, has much less ground substance than those with loosely packed fibers. Sciences, Culinary Arts and Personal Plus, get practice tests, quizzes, and personalized coaching to help you Specialised Connective Tissues. Log in or sign up to add this lesson to a Custom Course. Blood. Loose connective tissue is found around veins, arteries, and organs. Dense connective tissue Slide 15 Elastic connective tissue Slide 28 Mucus connective tissue Slide 87 . Elastic fibers are like rubber bands — they can stretch to a certain point and will then snap back to their original position. Bones Storage – (energy, electrolytes) -- Ex. Formed by osteoblasts Matrix = lamellae layers, collagen Inorganic salts give bones its hardness Compact and spongy. Your strength is actually the product of your muscles along with the dense regular connective tissue of your tendons. In comparison to loose connective tissue, dense tissue has a higher proportion of collagenous fibers to … 5 The fiber orientation is unidirectional for the purpose of attenuating unidirectional forces. a. Epithelial tissue b. Connective tissue c. Muscle tissue d. Nervous tissue. Connective tissues aren't, as the name suggests, merely just tissues that connect tissues or organs to one another; they are also responsible for anchoring, separating, and encasing other tissues and organs within the body. - 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 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. imaginable degree, area of Tendons may also attach muscles to structures such as the eyeball.

Dense Connective Tissues 3. Loose connective tissue 2. On the basis of the arrangement of … 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. © copyright 2003-2020 Study.com. Collagen and elastin are added to many beauty products. Now, you may think that it's your muscles alone that make you strong but it's not. What are the differences between a tendon and a ligament? Elastin fibers work like elastic bands. Irregular You can test out of the The collagen fibers are densely packed together and arranged in parallel to each other. Connective tissue is one of the basic animal tissue. Wikibuy Review: A Free Tool That Saves You Time and Money, 15 Creative Ways to Save Money That Actually Work. It also creates a barrier that prevents microbes and/or bacteria from passing between the fibers to the underlying tissues and organs. This matrix allows connective tissues to bear weight and endure the impacts, traumas, and pulling forces that no other tissue in the body can survive. What are the Different Types of Human Tissue. Visit the Middle School Life Science: Homework Help Resource page to learn more. The structure of connective tissue varies from soft gel-like loose (areolar) connective tissue to hard bones. Tendons are dense connective tissues that join muscle to bone and play a vital role in overall joint stability and function. The cells of cartilage, called chondrocytes, are isolated in small lacunae within the matrix. - Function, Types & Structure, Alveolar vs. Tubular Glands: Definition, Shapes & Examples, Human Anatomy & Physiology: Help and Review, Middle School Life Science: Help and Review, High School Biology: Homework Help Resource, Certified Nutrition Specialist (CNS): Test Prep & Study Guide, Introduction to Environmental Science: Help and Review, Introduction to Physical Geology: Help and Review, MTTC Integrated Science (Secondary)(094): Practice & Study Guide, ScienceFusion The Human Body: Online Textbook Help, ScienceFusion Earth's Water & Atmosphere: Online Textbook Help, UExcel Science of Nutrition: Study Guide & Test Prep. Connective tissue 1. www.slideshare.net 2. Example: e. For example, this tissue tensile strength allows it to withstand pulling forces exerted in one direction when a person flexes his or her arm. Dense 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). Dense regular connective tissue is mainly made up of type I collagen fibers. There are three subtypes of dense connective tissue: irregular, regular and elastic. Dense Connective Tissue. dense regular, dense irregular, elastic Formed by fibroblasts. Dense Connective Tissue: The three types of dense connective tissue are dense regular, dense irregular, and elastic tissue. Already registered? DEFINITION “Connective tissues (CT) are a group of tissues which connects or binds other tissues … As a member, you'll also get unlimited access to over 83,000 Connective tissue - Connective tissue - Cartilage: Cartilage is a form of connective tissue in which the ground substance is abundant and of a firmly gelated consistency that endows this tissue with unusual rigidity and resistance to compression. The function of dense regular connective tissue is (a) elastic recoil (b) binding and support (c) encapsulation of blood vessels (d) articulation. The high density of collagen fibers accounts for the high degree of tensile strength and lack of extensibility in these tissue. Function of Dense Irregular Connective Tissue:-Sustains tissue tension-Durable. flashcard set{{course.flashcardSetCoun > 1 ? areolar tissue:- consist of collagen and elastic fibers and cells like fibroblasts, macrophages, adipocytes etc present in the semifluid ground substance, they are present in hypodermis, papillary region of dermis and body organs. Describe the relationship between the structure and function of dense regular collagen. Dense regular connective tissue fibers are parallel to each other, enhancing tensile strength and resistance to stretching in the direction of the fiber … Objectives •Describe each type of connective tissue (CT) and explain where they are found. Generally, dense regular connective tissue forms tendons, the cords that attach muscle to bone, and aponeuroses — the flat, sheet-like tendons that attach muscles to other muscles or muscles to bone. There are three different types of dense connective tissue: dense regular connective tissue, dense irregular connective tissue, and elastic connective tissue.
