It is lighter than compact bone and found in the interior of some bones and at the end of long bones. Cartilage and bone are supportive tissue. In dense irregular connective tissue, the direction of fibers is random. electrons pass through any cross section across the wire's width at a steady rate. Chapter 4 Tissues Key Concepts Flashcards | Quizlet Cartilage contains chondrocytes and is somewhat flexible. Dense connective tissue contains more collagen fibers than does loose connective tissue. From top, LM 300, LM 1200, LM 1016. White adipose tissue can be found protecting the kidneys and cushioning the back of the eye. Dense connective tissue is reinforced by bundles of fibers that provide tensile strength, elasticity, and protection. conveys tissue fluid and strengthens organs Areolar tissue is a reservoir for water, salts and fibroblasts What does adipose tissue contain? LM 800. Function: Wraps and cushions organs, macrophages phagocytize bacteria, holds and conveys tissue fluid. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. -Located under epithelia and is widely distributed. A plate of hyaline cartilage at the ends of bone allows continued growth until adulthood. Jan 27, 2022 OpenStax. 3. the stronger the attraction between particles, the greater the surface tension. Fibersfunction in support; secreted by fibroblasts. . Like blood cells, mast cells are derived from hematopoietic stem cells and are part of the immune system. Clusters of mesenchymal cells are scattered throughout adult tissue and supply the cells needed for replacement and repair after a connective tissue injury. On rare occasions, a sudden serious injury will cause tendinitis.

This tissue gives rigid support as well as elasticity. Legal. The surface of hyaline cartilage is smooth. In some tissues, fibers crisscross and form a mesh. The ligaments in the vocal folds and between the vertebrae in the vertebral column are composed of dense regular elastic tissue. Connective tissues come in a vast variety of forms, yet they typically have in common three characteristic components: cells, large amounts of amorphous ground substance, and protein fibers. 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. It fills the spaces between muscle fibers, surrounds blood and lymph vessels, and supports organs in the abdominal cavity. Compact bone is solid and has greater structural strength. Fluid tissue, for example blood and lymph, is characterized by a liquid matrix and no supporting fibers. Bone tissue is highly vascularized. Collagen fibers, while flexible, have great tensile strength, resist stretching, and give ligaments and tendons their characteristic resilience and strength. Lymph contains a liquid matrix and white blood cells. consent of Rice University. Platelets are cell fragments involved in blood clotting. 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). Q. Connective tissues separate and cushion organs, protecting them from shifting or traumatic injury. A few cells can be seen squeezed between the fibers. Function: tensile strength with the ability to . A plate of hyaline cartilage at the ends of bone allows continued growth until adulthood. tissues (part 1) Flashcards | Quizlet Both components of the matrix, organic and inorganic, contribute to the unusual properties of bone. In loose connective tissue, the fibers are loosely organized, leaving large spaces in between. As a consequence, it displays greater resistance to stretching. Dense regular elastic tissue contains elastic fibers in addition to collagen fibers. Your opponent stands ready as you prepare to hit the serve, but you are confident that you will smash the ball past your opponent. It forms the lamina propria of mucus membranes; packages organs; surrounds capillaries. Wraps and cushions organs 2. All of these fiber types are embedded in ground substance. That dull ache in the wrist that you ignored through the summer is now an unbearable pain. Human Anatomy and Physiology Global Edition - (4 - Tissue - Studocu Located in the dermis of the skin and in fibrous capsules of organs and of joints. These serve to hold organs and other tissues in place and, in the case of adipose tissue, isolate and store energy reserves. Without collagen, bones would be brittle and shatter easily. The matrix is the most abundant feature for loose tissue although adipose tissue does not have much extracellular matrix. Collagen, Reticular, Elastic. store fat and protect organs Reticular connective tissue forms? Cartilage contains chondrocytes and is somewhat flexible. Most often, the condition results from repetitive motions over time that strain the tendons needed to perform the tasks. Difficulty swallowing, or clinically referred to as dysphagia, poses increased concern when drinking beverages. In dense irregular connective tissue, the direction of fibers is random. A few cells can be seen squeezed between the fibers. What is the description of connective tissue fibers? Anatomy & Physiology Chapter 4 Flashcards | Quizlet In this way, specialized lymphatic capillaries transport absorbed fats away from the intestine and deliver these molecules to the blood. Dense regular connective tissue fibers are parallel to each other, enhancing tensile strength and resistance to stretching in the direction of the fiber orientations. 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). Protein fibers fall into three major groups: collagen fibers that are thick, strong, flexible, and resist stretch; reticular fibers that are thin and form a supportive mesh; and elastin fibers that are thin and elastic. chapter 4 new part 2 Flashcards | Quizlet Dense connective tissue is reinforced by bundles of fibers that provide tensile strength, elasticity, and protection. LM 400. with stands great tensile strength in one direction ( tendons, ligaments) dense . 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 ([link]). What type of connective tissue should you expect ligaments to contain? Types of Tissues Flashcards | Quizlet Bones rigid extracellular matrix contains mostly collagen fibers embedded in a mineralized ground substance containing hydroxyapatite, a form of calcium phosphate. holds and conveys tissue fluid Location: Widely distributed under epithelia of body. Fibroblasts are present in all connective tissue proper ([link]). - Relative strength: - Function: wraps and cushions organs; its macrophages phagocytize bacteria; plays important role in inflammation; holds and conveys tissue fluid. The game is over for now. White adipose tissue is most abundant. (Micrograph provided by the Regents of University of Michigan Medical School 2012), (a) Dense regular connective tissue consists of collagenous fibers packed into parallel bundles. Explain surface tension. Persons whose jobs and hobbies involve performing the same movements over and over again are often at the greatest risk of tendinitis. Surgical repair of a tendon is painful. White fat contributes mostly to lipid storage and can serve as insulation from cold temperatures and mechanical injuries. Elastic fiber contains the protein elastin along with lesser amounts of other proteins and glycoproteins. Both components of the matrix, organic and inorganic, contribute to the unusual properties of bone. Blood is considered a specialized form of connective tissue. It contains all the cell types and fibers previously described and is distributed in a random, web-like fashion. Wraps and cushions organs, holds and conveys tissue fluid during inflammation (packages organs, surrounds capillaries) loose adipose connective tissue. These cells can differentiate into any type of connective tissue cells needed for repair and healing of damaged tissue. Wraps and cushions organs, plays a role in inflammation; holds and conveys tissue fluid. Concept Map of Tissues Flashcards | Quizlet Their effectiveness at storing large amounts of fat is witnessed in obese individuals. While no treatment is currently available, it is often recommended that liquids be thickened to improve the safety of swallowing and prevent liquids from being . Blood and lymph are fluid connective tissues. As may be obvious from its name, one of the major functions of connective tissue is to connect tissues and organs. 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. In adults, new connective tissue cells originate from the ________. Adipocytes are cells that store lipids as droplets that fill most of the cytoplasm. Organ capsules (collagenous type) and walls of arteries (elastic type) contain dense irregular connective tissue. View the University of Michigan Webscope to explore the tissue sample in greater detail. Structurally, all connective tissues contain cells that are embedded in an extracellular matrix stabilized by proteins. Connective tissues provide support and assist movement, store and transport energy molecules, protect against infections, and contribute to temperature homeostasis. Collagen fiber is made from fibrous protein subunits linked together to form a long and straight fiber. Supportive connective tissuebone and cartilageprovide structure and strength to the body and protect soft tissues. Transport of fluid, nutrients, waste, and chemical messengers is ensured by specialized fluid connective tissues, such as blood and lymph. The example is from dog tissue. The macrophage cells are an essential component of the immune system, which is the bodys defense against potential pathogens and degraded host cells. Bones rigid extracellular matrix contains mostly collagen fibers embedded in a mineralized ground substance containing hydroxyapatite, a form of calcium phosphate. CH 11: Surface Tension, Viscosity, Capillary Action Epithelial, Connective, Muscle, & Nervous Tissue Flashcards What is tendinitis and how did it happen? These granules contain the chemical signals histamine and heparin. The formed elements circulating in blood are all derived from hematopoietic stem cells located in bone marrow ([link]). Adipose cells store surplus energy in the form of fat and contribute to the thermal insulation of the body. Fibrocartilage is tough because it has thick bundles of collagen fibers dispersed through its matrix, which allows it to resist compression and absorb shock. Collagen fibers, while flexible, have great tensile strength, resist stretching, and give ligaments and tendons their characteristic resilience and strength. The number and type of adipocytes depends on the tissue and location, and vary among individuals in the population. Cross-linking . Discuss how blood fulfills this role. delicate network of interwoven fibers. Connective tissue that conveys tissue fluid and strengthens organs. Answer: Click at the bottom of the quiz for the answers. Fibroblasts are the most abundant and secrete many protein fibers, adipocytes specialize in fat storage, hematopoietic cells from the bone marrow give rise to all the blood cells, chondrocytes form cartilage, and osteocytes form bone. Access for free athttps://openstax.org/books/anatomy-and-physiology. epithelial tissues or glands are classified based on: shape of cells, number of cell layers, and where secretions are released. Learn more about how Pressbooks supports open publishing practices. The chemical nature and physical layout of the extracellular matrix and proteins vary enormously among tissues, reflecting the variety of functions that connective tissue fulfills in the body. The many mitochondria in the cytoplasm of brown adipose tissue help explain its efficiency at metabolizing stored fat. As an Amazon Associate we earn from qualifying purchases. Composed mainly of dense connective tissues, it serves as a tough, internal framework that surrounds muscles, bones, and nerves. Platelets are cell fragments involved in blood clotting. The macrophage cell is a large cell derived from a monocyte, a type of blood cell, which enters the connective tissue matrix from the blood vessels. Embedded within the cartilage matrix are chondrocytes, or cartilage cells, and the space they occupy are called lacunae (singular = lacuna). The superficial fascia is found just deep to the cutaneous membrane (or skin) and is typically composed of a combination of areolar and adipose connective tissues. It can appear yellow and owes its color to carotene and related pigments from plant food. -function: wraps and cushions organs; its macrophages phagocytize bacteria; plays an important role in inflammation; holds and conveys tissue fluid Reticular Connective Tissue resembles areolar tissue but the matrix is made up of only reticular fibers, found in bone marrow, spleen, liver, and lymph nodes Connective Tissue Supports and Protects - Anatomy & Physiology We recommend using a . Connective tissue that attaches muscles and bones. Can you name the 10 tissue types shown in the histology slides? Loose connective tissue is found between many organs where it acts both to absorb shock and bind tissues together. Cellularity, specialized contacts, polarity, supported by connective tissue, and regeneration. Organ capsules (collagenous type) and walls of arteries (elastic type) contain dense irregular connective tissue. The extracellular matrix contains fluid, proteins, polysaccharide derivatives, and, in the case of bone, mineral crystals. Compact bone is solid and has greater structural strength. Test Match Created by bouselel Terms in this set (17) Four Types Of Tissue Connective, Muscular, Epithelial, Nervous Areolar Wraps and cushions organs; its phagocytes engulf bacteria; plays important role in inflammation; holds and conveys tissue fluid Stratified Squamous Protects underlying tissues in areas subjected to abrasion Pseudostratified Some cells have the ability to cross the endothelial layer that lines vessels and enter adjacent tissues. The proteoglycan attracts and traps available moisture forming the clear, viscous, colorless matrix you now know as ground substance. Elastic fibers are prominent in elastic tissues found in skin and the elastic ligaments of the vertebral column. Transport of fluid, nutrients, waste, and chemical messengers is ensured by specialized fluid connective tissues, such as blood and lymph. 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. It makes up a template of the embryonic skeleton before bone formation.

Under, or deep to, the superficial fascia is the deep fascia. Areolar connective tissue. They originate in the mesodermal germ layer and differentiate from mesenchyme and hematopoietic tissue in the bone marrow. (b) Dense irregular connective tissue consists of collagenous fibers interwoven into a mesh-like network. In contrast, white fat adipocytes store lipids as a single large drop and are metabolically less active. The major component of the matrix is a ground substance often crisscrossed by protein fibers. areolar matrix includes ground substance and the following fibers: adipose matrix includes ground substance and the following fibers: dense connective tissue matrix includes ground substance and the following fibers: connective tissue that transports materials in a plasma matrix is: connective tissue that stores minerals and anchors muscles is, connective tissue that covers and protects the ends of long bones is, compact bone matrix includes nonfibrous ____________. Elastic cartilage can stretch and recoil to its original shape because of its high content of elastic fibers. 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. Fibrocytes, adipocytes, and mesenchymal cells are fixed cells, which means they remain within the connective tissue. Connective tissue proper includes loose connective tissue and dense connective tissue. This type of tissue gives the walls of large arteries and respiratory passages strength and the ability to regain original shape after stretching. It can appear yellow and owes its color to carotene and related pigments from plant food. The matrix is the most abundant feature for loose tissue although adipose tissue does not have much extracellular matrix. The three main types of cartilage tissue are hyaline cartilage, fibrocartilage, and elastic cartilage (Figure \(\PageIndex{6}\)). These serve to hold organs and other tissues in place and, in the case of adipose tissue, isolate and store energy reserves. function of simple columnar epithelium with microvilli, in ___________ , the entire secretory cell ruptures, releasing secretions and dead cell fragments (e.g., sebaceous glands), __________ secrete their products by exocytosis (e.g., sweat, pancreas, salivary), connective tissue that conveys tissue fluids and strengthens organs is_______, connective tissue that stores fat and protects organs is ______, connective tissue that attaches muscle and bones is__________. Osteocytes, bone cells like chondrocytes, are located within lacunae. Areolar and Adipose matrix includes ground substance and the following fibers As you might expect, a fibrocyte, a less active form of fibroblast, is the second most common cell type in connective tissue proper. It serves to connect the cutaneous membrane to the underlying organs. and you must attribute OpenStax. Except where otherwise noted, textbooks on this site It derives its name from the Latin reticulus, which means little net.. Cytokines recruit other cells of the immune system to infected sites and stimulate their activities. A layer of dense irregular connective tissue, the perichondrium, encapsulates the cartilage. Location: beneath skin, surrounds organs. Elastic cartilage contains elastic fibers as well as collagen and proteoglycans. Unlike cartilage, bone tissue can recover from injuries in a relatively short time.

Bones are made of a rigid, mineralized matrix containing calcium salts, crystals, and osteocytes lodged in lacunae. Want to cite, share, or modify this book? In contrast, fixed macrophages are permanent residents of their tissues. 4.3: Connective Tissue Supports and Protects Cancellous bone is spongy and less solid than compact bone. Surgical repair of a tendon is painful. As we explained in Chapter 1, tissues are organized into organs such as the kidneys and heart. why is blood classified as connective tissue? Secreted by fibroblasts, ground substance is made of polysaccharides, specifically hyaluronic acid, and proteins. The roots ped and pod mean "foot." The root phob means "fear." The root port means "to carry" or "bring." Cartilaginous tissue is avascular, thus all nutrients need to diffuse through the matrix to reach the chondrocytes. Which connective tissue specializes in storage of fat? LM 1600. Q. The matrix plays a major role in the functioning of this tissue. 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. It provides protection to internal organs and supports the body. Dense connective tissue contains more collagen fibers than does loose connective tissue. The brown adipocytes store lipids as many droplets, and have high metabolic activity.

Brown adipose tissue is more common in infants, hence the term baby fat. In adults, there is a reduced amount of brown fat and it is found mainly in the neck and clavicular regions of the body. are not subject to the Creative Commons license and may not be reproduced without the prior and express written Fibroblasts produce this fibrous tissue. Between 4-16% of adults in the United States have experienced difficulty swallowing at some point during their lives. The mast cell, found in connective tissue proper, has many cytoplasmic granules. . In fluid connective tissue, in other words, lymph and blood, various specialized cells circulate in a watery fluid containing salts, nutrients, and dissolved proteins. 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. Which connective tissue specializes in storage of fat? No blood vessels supply cartilage tissue. Adipose cells store surplus energy in the form of fat and contribute to the thermal insulation of the body. What is tendinitis and how did it happen? It contains all the cell types and fibers previously described and is distributed in a random, web-like fashion. She issues a stern warning about the risk of aggravating the condition and the possibility of surgery. OpenStax is part of Rice University, which is a 501(c)(3) nonprofit.
