Other cells move in and out of the connective tissue in response to chemical signals. Loose connective tissue proper includes adipose tissue, areolar tissue, and reticular tissue. Bone tissue is highly vascularized. It fills the spaces between muscle fibers, surrounds blood and lymph vessels, and supports organs in the abdominal cavity. Loose connective tissue proper includes adipose tissue, areolar tissue, and reticular tissue. A histologist examines a tissue slide and observes many fibers tightly packed together in a parallel arrangement. Cartilaginous tissue is avascular, thus all nutrients need to diffuse through the matrix to reach the chondrocytes. In fluid connective tissue, in other words, lymph and blood, various specialized cells circulate in a watery fluid containing salts, nutrients, and dissolved proteins. Elastic fibers are prominent in elastic tissues found in skin and the elastic ligaments of the vertebral column. Anatomy & Physiology Chapter 4 Flashcards | Quizlet Adipose tissue consists mostly of fat storage cells, with little extracellular matrix ([link]). It makes up a template of the embryonic skeleton before bone formation. These serve to hold organs and other tissues in place and, in the case of adipose tissue, isolate and store energy reserves. Connective tissue proper includes loose connective tissue and dense connective tissue. Under the microscope, tissue samples appear clear. . From top, LM 1000, LM 200. Tendinitis is the inflammation of a tendon, the thick band of fibrous connective tissue that attaches a muscle to a bone. Discuss how blood fulfills this role. Connective Tissue: Tendinitis Q. It contains all the cell types and fibers previously described and is distributed in a random, web-like fashion. store fat and protect organs Reticular connective tissue forms? The matrix is the most abundant feature for loose tissue although adipose tissue does not have much extracellular matrix. Adipose cells store surplus energy in the form of fat and contribute to the thermal insulation of the body. Accessibility StatementFor more information contact us atinfo@libretexts.org. A few distinct cell types and densely packed fibers in a matrix characterize these tissues. types of tissue function Flashcards | Quizlet Cytokines recruit other cells of the immune system to infected sites and stimulate their activities. For a current set up in wire for 28.0 d, a total of, 1.3610261.36 \times 10 ^ { 26 } While older adults are at risk for tendinitis because the elasticity of tendon tissue decreases with age, active people of all ages can develop tendinitis. This tissue gives rigid support as well as elasticity. The distinctive appearance of cartilage is due to polysaccharides called chondroitin sulfates, which bind with ground substance proteins to form proteoglycans. LM 800. Many different cells contribute to the formation of connective tissues. A histologist examines a tissue slide and observes many fibers tightly packed together in a parallel arrangement. There are two major categories of dense connective tissue: regular and irregular. this is called __________, Anatomy - Exam 2 Practice Questions - Histolo, muscles of lower limbs (leg, foot, and toes), muscles of the lower limbs (thigh, hip, and k, muscles of the upper limb (forearm, elbow, ha, John David Jackson, Patricia Meglich, Robert Mathis, Sean Valentine, David N. Shier, Jackie L. Butler, Ricki Lewis. Cellularity Composed almost entirely of cells with minimal extra cellular material Specialized contacts Cells joined by special junctions to stick together and communicate. In all cases, overuse of the joint causes a microtrauma that initiates the inflammatory response. compact bone matrix includes ground substance and the following fiber: hyaline cartilage matrix includes ground substance and the following fiber: ___________ contains a large amount of an extracellular matrix. Tendinitis is the inflammation of a tendon, the thick band of dense regular connective tissue that attaches a muscle to a bone. Dense connective tissue contains more collagen fibers than does loose connective tissue. 31 Transitional Epithelium Several cell layers, basal cells are cuboidal . Blood contains formed elements derived from bone marrow. The surface of hyaline cartilage is smooth. type of connective tissue that provides strength to the body and protects soft tissue synovial membrane connective tissue membrane that lines the cavities of freely movable joints, producing synovial fluid for lubrication tight junction forms an impermeable barrier between cells tissue group of cells that are similar in form and perform related . Dense Connective Tissue. Jan 27, 2022 OpenStax. This book uses the The mesenchymal cell is a multipotent adult stem cell. For active individuals, stretches before exercising and cross training or changing exercises are recommended. Dense connective tissue contains more collagen fibers than does loose connective tissue. Both tissues have a variety of cell types and protein fibers suspended in a viscous ground substance. Cells circulate in a liquid extracellular matrix. Reticular tissue is a mesh-like, supportive framework for soft organs such as lymphatic tissue, the spleen, and the liver (Figure \(\PageIndex{4}\)). 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. Reticular tissue is a mesh-like, supportive framework for soft organs such as lymphatic tissue, the spleen, and the liver ([link]). 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 component of the matrix is a ground substance often crisscrossed by protein fibers. Elastic fiber contains the protein elastin along with lesser amounts of other proteins and glycoproteins. Answer: Click at the bottom of the quiz for the answers. Exercise 5: classification of tissues Flashcards | Quizlet The example is from dog tissue. Three main types of fibers are secreted by fibroblasts: collagen fibers, elastic fibers, and reticular fibers. Connective tissue in the tendon does not have abundant blood supply and heals slowly. Dense regular elastic tissue contains elastin fibers in addition to collagen fibers, which allows the ligament to return to its original length after stretching. She issues a stern warning about the risk of aggravating the condition and the possibility of surgery. Bone is a highly vascularized tissue. Dense connective tissue is reinforced by bundles of fibers that provide tensile strength, elasticity, and protection. From top, LM 300, LM 1200, LM 1016.
