. Cytokines recruit other cells of the immune system to infected sites and stimulate their activities. Without collagen, bones would be brittle and shatter easily. Lastly, found in between the deep fascia and the serous membranes, is the subserous fascia. Under the microscope, tissue samples appear clear. The matrix contains very few blood vessels. Elastic fibers are prominent in elastic tissues found in skin and the elastic ligaments of the vertebral column. Severe cases of tendinitis can even tear loose a tendon. The mast cell, found in connective tissue proper, has many cytoplasmic granules. The mesenchymal cell is a multipotent adult stem cell. Viscosity's resistance to flow is a combination of the size of the . Connect tissues provide support and assist movement, store and transport energy molecules, protect against infections, and contribute to temperature homeostasis. The many mitochondria in the cytoplasm of brown adipose tissue help explain its efficiency at metabolizing stored fat. 4.3B: Types of Connective Tissue - Medicine LibreTexts Cancellous bone looks like a sponge under the microscope and contains empty spaces between trabeculae, or arches of bone proper. The example is from dog tissue. In contrast, white fat adipocytes store lipids as a single large drop and are metabolically less active. The major types of connective tissue are connective tissue proper, supportive tissue, and fluid tissue. A. Blood and lymph are fluid connective tissues. 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 Tendinitis is the inflammation of a tendon, the thick band of dense regular connective tissue that attaches a muscle to a bone. Chapter 4 Tissues Key Concepts Flashcards | Quizlet Their effectiveness at storing large amounts of fat is witnessed in obese individuals. They originate in the mesodermal germ layer and differentiate from mesenchyme and hematopoietic tissue in the bone marrow. Wraps and cushions organs 2. Elastic cartilage can stretch and recoil to its original shape because of its high content of elastic fibers. Other cells move in and out of the connective tissue in response to chemical signals. This is probably ________. There are two basic types of adipocytes: white and brown. Connective tissue proper includes loose connective tissue and dense connective tissue. The proteoglycan attracts and traps available moisture forming the clear, viscous, colorless matrix you now know as ground substance.
