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. Connective tissue proper > loose - gel-like matrix w/ all 3 fiber types - cells and fibroblasts, machrophages, mast cells, WBC - wraps/cushions organs - macrophages eat bacteria - role w/ inflammation - holds/conveys tissue fluid - found under epithelia, forms lamina propria of mucus membrane and packages organs and surrounds capillaries Click at the bottom of the quiz for the answers. Two major forms of supportive connective tissue, cartilage and bone, allow the body to maintain its posture and protect internal organs. citation tool such as, Authors: J. Gordon Betts, Kelly A. As you toss the ball high in the air, a burning pain shoots across your wrist and you drop the tennis racket. Lymph drains into blood vessels, delivering molecules to the blood that could not otherwise directly enter the bloodstream. It contains all the cell types and fibers previously described and is distributed in a random, web-like fashion. No blood vessels supply cartilage tissue. Visit this link to test your connective tissue knowledge with this 10-question quiz. These fibers hold connective tissues together, even during the movement of the body. Some white blood cells have the ability to cross the endothelial layer that lines blood vessels and enter adjacent tissues. 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. A few distinct cell types and densely packed fibers in a matrix characterize these tissues. It can appear yellow and owes its color to carotene and related pigments from plant food. anatomy-connective tissue Flashcards | Quizlet Platelets are cell fragments involved in blood clotting. THE BENEFITS OF HAIR MINERAL TESTING ANALYSIS FOR ATHLETIC PERFORMANCE Hair mineral testing analysis is an invaluable tool for athletes and their coaches seeking to optimize athletic performance. (b) Dense irregular connective tissue consists of collagenous fibers interwoven into a mesh-like network. Transport of fluid, nutrients, waste, and chemical messengers is ensured by specialized fluid connective tissues, such as blood and lymph. 1. the energy required to increase the surface area of a liquid (surfactant) 2. a measure of the inward pull by interior particles. If the cobalt was initially at rest, use the conservation of momentum equation to determine its speed following the gamma ray emission. The OpenStax name, OpenStax logo, OpenStax book covers, OpenStax CNX name, and OpenStax CNX logo Discuss how blood fulfills this role. Connective tissue proper includes the fixed cells fibrocytes, adipocytes, and mesenchymal cells. As you have seen from the tissue types discussed above, the main role of connective tissues is to form the structural framework of the body. This is due to what is behind each of the properties. Surface Tension, the resistance of the surface to external forces is a result of the attraction of the molecules and the level of hydrogen bonding.
