Elastic fibers contain the protein elastin along with lesser amounts of other proteins and glycoproteins. The three main types of cartilage tissue are hyaline cartilage, fibrocartilage, and elastic cartilage (Figure \(\PageIndex{6}\)). This tissue is no longer present after birth, leaving only scattered mesenchymal cells throughout the body. There are three main groups of connective tissues: Loose connective tissue holds organs in place and attaches epithelial tissue to other underlying tissues. ... Review Sheet 6A- Classification of Tissues. There are two basic types of adipocytes: white and brown. The number and type of adipocytes depends on the tissue and location, and vary among individuals in the population. Visit this link (http://www2.yvcc.edu/histologyzoomer...issueQuiz.html) to test your connective tissue knowledge with this 10-question quiz. General connective tissue. The three broad categories of connective tissue are classified according to the characteristics of their ground substance and the types of fibers found within the matrix (Table \(\PageIndex{1}\)). Examples of connective tissues include tendons, ligaments, bones, blood, adipose and areolar tissues. Two major forms of supportive connective tissue, cartilage and bone, allow the body to maintain its posture and protect internal organs. The second category includes those where the connective tissue is the target of antibodies directed against it. Without mineral crystals, bones would flex and provide little support. Loose irregular connective tissue contains numerous cells and a loose fiber arrangement in a moderately viscous fluid matrix. Legal. Great deal of noncellular, nonliving material between the cells of connective tissue. Connective tissues help provide mechanical strength, shape and rigidity to the organs and keep them in place. Cartilage is a hard but flexible skeletal tissue consisting of living cells embedded in a matrix. Elastic cartilage contains elastic fibers as well as collagen and proteoglycans. It is a fluid connective tissue. Composed mainly of dense connective tissues, it serves as a tough, internal framework that surrounds muscles, bones, and nerves. Summary. Polysaccharides and proteins secreted by fibroblasts combine with extra-cellular fluids to produce a viscous ground substance that, with embedded fibrous proteins, forms the extra-cellular matrix. Persons whose jobs and hobbies involve performing the same movements over and over again are often at the greatest risk of tendinitis. What are some examples of connective tissue? 1. These inorganic salts are responsible for hardness of the bone. When irritated or damaged, mast cells release histamine, an inflammatory mediator, which causes vasodilation and increased blood flow at a site of injury or infection, along with itching, swelling, and redness you recognize as an allergic response. The tendons connect the skeletal muscles with the bones.

Functions of Connective Tissues. Types of Connective Tissue. Reticular fibers are also formed from the same protein subunits as collagen fibers; however, these fibers remain narrow and are arrayed in a branching network. The first connective tissue to develop in the embryo is mesenchyme, the stem cell line from which all connective tissues are later derived. The LibreTexts libraries are Powered by MindTouch® and are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program, and Merlot. As with dense regular connective tissue, when elastic fibers running in random directions outnumber collagen fibers, the tissue is a dense irregular elastic connective tissue. Macrophages, mast cells, lymphocytes, and plasma cells are found in connective tissue proper but are actually part of the immune system protecting the body. Fibroblasts are present in all connective tissue proper (Figure \(\PageIndex{1}\)). Lymph: Both strong and flexible, it is found in the rib cage and nose and covers bones where they meet to form moveable joints. 1. 28 terms. They are found throughout the body, but are most abundant in the reticular tissue of soft organs, such as liver and spleen, where they anchor and provide structural support to the parenchyma (the functional cells, blood vessels, and nerves of the organ). Matrix of cartilage In bone, the matrix is rigid and described as calcified because of the deposited calcium salts. Under membranes there can be several different layers of connective tissues that function to connect internal structures to the rest of the body. It consists of a transparent, jelly-like sticky matrix containing numerous fibres and cells and abundant mucin. organic matter. Bone is the hardest connective tissue. Tissues are either classified as proper, embryonic, or specialized. (a) Tendon : Tendons are cord-like, very tough, inelastic bundles of white collagen fibres bound together by areolar tissue. alholmes. Lymph is a colourless fluid that has filtered out of the blood capillaries. Characteristics of connective tissue. Erythrocytes, red blood cells, transport oxygen and some carbon dioxide. Myxomatous degeneration – a … Cytokines recruit other cells of the immune system to infected sites and stimulate their activities. They originate in the mesodermal germ layer and differentiate from mesenchyme and hematopoietic tissue in the bone marrow. As you toss the ball high in the air, a burning pain shoots across your wrist and you drop the tennis racket. Fluid Connective Tissue : (Vascular Tissue) All connective tissues derive from the mesodermal layer of the embryo. Under the microscope, a tissue specimen shows cells located in spaces scattered in a transparent background. As a consequence, it displays greater resistance to stretching. For more information contact us at info@libretexts.org or check out our status page at https://status.libretexts.org. This tissue combines strength with great flexibility. Figure 4.1.3 – Tissue Membranes: The two broad categories of tissue membranes in the body are (1) connective tissue membranes, which include synovial membranes, and (2) epithelial membranes, which include mucous membranes, serous membranes, and the cutaneous membrane, in other words, the skin. The external ear contains elastic cartilage. As may be obvious from its name, one of the major functions of connective tissue is … In other tissues, stretching in several directions is achieved by alternating layers where fibers run in the same orientation in each layer, and it is the layers themselves that are stacked at an angle. Roaming, or free, macrophages move rapidly by amoeboid movement, engulfing infectious agents and cellular debris. Tendinitis is the inflammation of a tendon, the thick band of dense regular connective tissue that attaches a muscle to a bone. The matrix plays a major role in the functioning of this tissue. Blood contains formed elements derived from bone marrow. View the University of Michigan Webscope (http://virtualslides.med.umich.edu/Histology/ Tendinitis is routinely diagnosed through a clinical examination. Cartilage is an example of a connective tissue. Unless otherwise noted, LibreTexts content is licensed by CC BY-NC-SA 3.0. Basically it has three components. Y… In some tissues, fibers crisscross and form a mesh. You hear of tennis and golfer’s elbow, jumper's knee, and swimmer’s shoulder. Lastly, found in between the deep fascia and the serous membranes, is the subserous fascia. Growth of cartilage occurs continuously due to multiplication of chondrocytes by mitosis, deposition of matrix within existing cartilage and from activity of the deeper cells of the perichondrium. rachel_grace2. Q. Connective tissue is made of which three essential components? The different types of connective tissue include adipose, fibrous, and elastic tissues as well as blood, bone, and cartilage. Blood vessels, nerves and muscles, all have a loose connective tissue wrapping. Connective tissues are divided into three groups: Loose Connective Tissue. Elastic fibers are prominent in elastic tissues found in skin and the elastic ligaments of the vertebral column. Cartilages. 1. The functions of connective tissue are protection, support, & binding other tissues together - reflected in matrix for strength & fibers for support. That dull ache in the wrist that you ignored through the summer is now an unbearable pain. Fluid tissue, for example blood and lymph, is characterized by a liquid matrix and no supporting fibers. Adipocytes are cells that store lipids as droplets that fill most of the cytoplasm. Hyaline cartilage, the most common type of cartilage in the body, consists of short and dispersed collagen fibers and contains large amounts of proteoglycans. Loose Connective Tissue: The loose connective tissue is the least specialized connective tissue in the body. Dense regular connective tissue consists of orderd and densely packed fibres and cells. The lacunae are also traversed by nerves and blood vessels. 1. Connective tissue that provides support and framework for the body consists of fibrous proteins and nonfibrous ground substance in varying proportions depending on their functions.. 2. What is tendinitis and how did it happen? Classification. Dense Connective Tissues 3. inorganic. After examining your swollen wrist, the doctor in the emergency room announces that you have developed wrist tendinitis. Connective tissues are made up of two proteins: collagen and elastin. It includes blood and lymph. Connective tissue consists of scattered cells immersed in an intercellular material called the matrix. The matrix usually includes a large amount of extracellular material produced by the connective tissue cells that are embedded within it. 16 terms. In case of severe pain, X-rays can be examined to rule out the possibility of a bone injury. She recommends icing the tender area, taking non-steroidal anti-inflammatory medication to ease the pain and to reduce swelling, and complete rest for a few weeks. Fibrocartilage is tough because it has thick bundles of collagen fibers dispersed through its matrix. Dense connective tissue proper is richer in fibers and may be regular, with fibers oriented in parallel as in ligaments and tendons, or irregular, with fibers oriented in several directions. Cartilage. 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. Further, there are three types of connective tissues. This tissue stores fat and insulates the body against heat loss. Q. The white blood cells (WBC’s) fight disease either by engulfing and destroying foreign. Lymph transports the nutrients (oxygen, glucose) that may have filtered out of the blood capillaries back into the heart to be recirculated in the body. connecting bones to each other, muscles to bones etc.) Three main types of fibers are secreted by fibroblasts: collagen fibers, elastic fibers, and reticular fibers. Skeletal tissue : Platelets are cell fragments involved in blood clotting. Collections of tissues joined in units to serve a common function compose organs. Connective tissues perform many functions in the body, but most importantly, they support and connect other tissues; from the connective tissue sheath that surrounds muscle cells, to the tendons that attach muscles to bones, and to the skeleton that supports the positions of the body. Answer: Click at the bottom of the quiz for the answers. 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. The distinctive appearance of cartilage is due to polysaccharides called chondroitin sulfates, which bind with ground substance proteins to form proteoglycans. So you may try to carefully prop up the lumber on the foundation. A. 1. A. Cartilage 3. This type of tissue gives the walls of large arteries and respiratory passages strength and the ability to regain original shape after stretching. Parts of the Cell. Brown adipose tissue is thermogenic, meaning that as it breaks down fats, it releases metabolic heat, rather than producing adenosine triphosphate (ATP), a key molecule used in metabolism. The major types of connective tissue are connective tissue proper, supportive tissue, and fluid tissue. Collagen is a protein found in the tendons, ligaments, skin, cornea, cartilage, bone and blood vessels. Cancer Classification. This is probably ________. The major component of the matrix is a ground substance often crisscrossed by protein fibers. Loose connective tissues are present all over the body, where support and elasticity both are needed. Under, or deep to, the superficial fascia is the deep fascia. dense regular connective tissue which is found in tendons and ligaments, and is shown below. However connective tissue differs from other types in that its cells are loosely, rather than tightly, packed within the ECM. Bone 4. Blood platelets disintegrate at the site of injury and help in the clotting of blood. A. cells, ground substance, and carbohydrate fibers, B. cells, ground substance, and protein fibers, C. collagen, ground substance, and protein fibers. This ground substance is usually a fluid, but it can also be mineralized and solid, as in bones. Reticular cells produce the reticular fibers that form the network onto which other cells attach. The brown adipocytes store lipids as many droplets, and have high metabolic activity. Connective tissue is an important biological tissue composed of an extracellular matrix that binds, anchors, and supports organs. 2. Fibrocytes, adipocytes, and mesenchymal cells are fixed cells, which means they remain within the connective tissue. Cartilage contains chondrocytes and is somewhat flexible. Although repetitive motions are unavoidable in many activities and may lead to tendinitis, precautions can be taken that can lessen the probability of developing tendinitis. This condition causes redness, swelling, and pain (also known as inflammation). The matrix in turn is composed of fibres and ground substance. In this way, specialized lymphatic capillaries transport absorbed fats away from the intestine and deliver these molecules to the blood. These serve to hold organs and other tissues in place and, in the case of adipose tissue, isolate and store energy reserves. Bones form endoskeleton of vertebrates. “ordinary” connective tissues “specialized” connective tissues: The adipose tissue is found beneath the skin, in the covering of the heart, around the blood vessels and kidney and in yellow bone marrow. Assignment • Classification of CT 22. Bulbber in whales is, in fact, an insulating fat body. Similarly, hump in camel is also rich in adipose tissue. Image Source: austincc.edu. ADVERTISEMENTS: Based on the composition, organization of the extracellular matrix, cell types and their functions, the connective tissue is classified into following three major types: 1. This tissue occurs in very few parts of the body. Have questions or comments? Dense connective tissue helps attach muscles to bones and link bones together at joints. The first category includes those that are inherited, usually due to a single-gene defect called a mutation. Adipose cells store surplus energy in the form of fat and contribute to the thermal insulation of the body. All of the preventive measures aim to increase the strength of the tendon and decrease the stress put on it. Many different cells contribute to the formation of connective tissues. Connective tissue is formed of cells and extracellular matrix (fig.1). There are many types of connective tissue disorders, such as: Connective tissue neoplasms including sarcomas such as hemangiopericytoma and malignant peripheral nerve sheath tumor in... Congenital diseases include Marfan syndrome and Ehlers-Danlos Syndrome. In contrast, fixed macrophages are permanent residents of their tissues. This is a factor contributing to the very slow healing of cartilaginous tissues. Protection is another major function of connective tissue, in the form of fibrous capsules and bones that protect delicate organs and, of course, the skeletal system. Classification of Connective Tissues. White adipose tissue is most abundant. Q. Connective tissue proper includes loose connective tissue and dense connective tissue. CONNECTIVE TISSUE PROPER (examples of these are shown below) loose irregular connective tissue ; dense irregular connective tissue; SPECIALISED CONNECTIVE TISSUES. Young athletes, dancers, and computer operators; anyone who performs the same movements constantly is at risk for tendinitis.

Elastic cartilage can stretch and recoil to its original shape because of its high content of elastic fibers. (b) Ligaments : Ligaments are cords formed by yellow elastic tissue in which many collagen fibres are bound together by areolar tissue. It fills the spaces between muscle fibers, surrounds blood and lymph vessels, and supports organs in the abdominal cavity. Connective tissue is a heterogeneous tissue class with assorted cell shapes and tissue architecture. The game is over for now. The following paragraphs will describe the general connective tissue, because the description of the other types of connective tissue is out of the purpose of this text. It makes up a template of the embryonic skeleton before bone formation. The surface of cartilage is surrounded by irregular connective tissue forming the perichondrium. In sharks and rays, the entire skeleton is cartilage. All of these fiber types are embedded in ground substance. Although it is the most abundant and widely distributed of the primary tissues, the amount of connective tissue in a particular organ varies. The cells present in the tendons are elongated fibroblasts which lie in almost continuous rows here and there. Both components of the matrix, organic and inorganic, contribute to the unusual properties of bone. Blood and lymph are fluid connective tissues. Connective tissues provide support and assist movement, store and transport energy molecules, protect against infections, and contribute to temperature homeostasis. In dense irregular connective tissue, the direction of fibers is random. The fibres are mostly of two types : (a) White collagen fibres. Each fat cell contains a large fat globule. Connective tissue in the tendon does not have abundant blood supply and heals slowly. s_van_16. The red blood corpuscles (RBC’s) carry oxygen to the tissues for the oxidation of food stuff. Matrix of bone is Some white blood cells have the ability to cross the endothelial layer that lines blood vessels and enter adjacent tissues. Red blood corpuscles and some blood proteins are absent in it. Access for free at https://openstax.org/books/anatomy-and-physiology. Like to the timber framing of a house, the connective tissue … Connective Tissue – Fibers and Ground Substance. There are two major categories of dense connective tissue: regular and irregular. Under the microscope, tissue samples appear clear. In loose connective tissue, the fibers are loosely organized, leaving large spaces in between. No blood vessels supply cartilage tissue. Heparin, also released as part of the inflammatory response, acts as an anticoagulant that prevents the formation of blood clots. Cartilage is a type of supporting connective tissue. Recall from the first section of this chapter that membranes form all the body linings and are made up of epithelial tissues with a layer of underlying connective tissue. A few distinct cell types and densely packed fibers in a matrix characterize these tissues. Q. Loose Connective Tissue 2. These disorders often involve the joints, muscles, and skin, but they can also involve other organs and organ systems, including the eyes, heart, lungs, kidneys, gastrointestinal tract, and blood vessels. Bone Imagine constructing a house using typical building components. Cardiovascular%20System/081-3_HISTO_40X.svs/view.apml) to explore the tissue sample in greater detail. Characterisitics. In adults, new connective tissue cells originate from the ________. A layer of dense irregular connective tissue, the perichondrium, encapsulates the cartilage. Composed of many types of cells 3. The areolar tissue is connective in function. In contrast, white fat adipocytes store lipids as a single large drop and are metabolically less active. Bone is a very strong and non-flexible vertebrate connective tissue. Transport of fluid, nutrients, waste, and chemical messengers is ensured by specialized fluid connective tissues, such as blood and lymph. For the passionate athlete, it may be time to take some lessons to improve technique. The osteoblasts are contained in lacunae (spaces) which are arranged in concentric circles present throughout the matrix. Cartilage and bone are supportive tissue. In the lymph, white blood cells are found in abundance. Areolar tissue shows little specialization. The proteoglycan attracts and traps available moisture forming the clear, viscous, colorless matrix you now know as ground substance. The formed elements circulating in blood are all derived from hematopoietic stem cells located in bone marrow (Figure \(\PageIndex{8}\)). The knee and jaw joints and the intervertebral discs are examples of fibrocartilage. A layer of dense irregular connective tissue covers cartilage. Without collagen, bones would be brittle and shatter easily. Connective tissue is the tissue that connects, separates and supports all other types of tissues in the body. Structurally, all connective tissues contain cells that are embedded in an extracellular matrix stabilized by proteins. The condition causes pain and tenderness in the area around a joint. Blood. It is lighter than compact bone and found in the interior of some bones and at the end of long bones. Examples of typical dense regular and dense irregular connective tissues consisting primarily of collagen fibers are shown in (Figure \(\PageIndex{5}\)). Q. Functions. Connective tissue disease refers to a group of disorders involving the protein-rich tissue that supports organs and other parts of the body. Dense connective tissue contains more collagen fibers than does loose connective tissue. Connective tissue is found between other tissue types and organs. Cartilage is a hard but flexible skeletal tissue consisting of living cells embedded … Bones, cartilage, blood, lymph, adipose tissue which is fat.
