Connective tissue proper includes loose connective tissue and dense connective tissue. Blood contains formed elements derived from bone marrow. The mast cell, found in connective tissue proper, has many cytoplasmic granules. lab quiz 2 tissues, integumentary system Flashcards | Quizlet Why does an injury to cartilage, especially hyaline cartilage, heal much more slowly than a bone fracture? 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. Cartilage and bone are supportive tissue. In some tissues, fibers crisscross and form a mesh. Collagen fibers, while flexible, have great tensile strength, resist stretching, and give ligaments and tendons their characteristic resilience and strength. The main property of elastin is that after being stretched or compressed, it will return to its original shape. are not subject to the Creative Commons license and may not be reproduced without the prior and express written A second type of embryonic connective tissue forms in the umbilical cord, called mucous connective tissue or Whartons jelly. then you must include on every physical page the following attribution: If you are redistributing all or part of this book in a digital format, White adipose tissue can be found protecting the kidneys and cushioning the back of the eye. Under the microscope, tissue samples appear clear. It allows water, salts, and various nutrients to diffuse through to adjacent or imbedded cells and tissues. Dense regular connective tissue fibers are parallel to each other, enhancing tensile strength and resistance to stretching in the direction of the fiber orientations. She interrupts your protests that you cannot stop playing. Chemical reactions (metabolism) are essential for cells to function and, thus, for the body as a whole to maintain boundaries, move, respond, digest, excrete, grow, and reproduce--all necessary life functions. A few distinct cell types and densely packed fibers in a matrix characterize these tissues. The matrix is the most abundant . Unlike epithelial tissue, which is composed of cells closely packed with little or no extracellular space in between, connective tissue cells are dispersed in a matrix. Blood contains formed elements derived from bone marrow. LM 1600. It contains all the cell types and fibers previously described and is distributed in a random, web-like fashion. 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. It forms the lamina propria of mucus membranes; packages organs; surrounds capillaries.
