Because connective tissue builds and heals much more slowly than does muscle, even a partial tear can take months to heal; in some cases, it may never heal completely. Connective tissue proper forms a compartment separated from all other tissues by the basal or external lamina, a layer containing type IV collagen. Basic Components of Connective Tissues 3. Function. 0. In connective tissue diseases, your immune system attacks the fibers that provide the framework and support for your body. 2. a new growth of tissue in which cell multiplication is uncontrolled and progressive. How does connective tissue differ from epithelial tissue?5. An example of loose connective tissue is subcutaneous tissue, as well as connective tissue, which fills the spaces between organs and accompanies blood vessels. The first connective tissue to develop in the embryo is mesenchyme, the stem cell line from which all connective tissues are later derived.Clusters of mesenchymal cells are scattered throughout adult tissue and supply the cells needed for replacement and repair after a connective tissue injury. Over time, ulcers or gangrene (tissue death) may develop if frequent or severe attacks are not prevented. Marfan syndrome is due to defective genes producing a protein fibrillin-1. Some people with mixed connective tissue disease have a family history of the condition. It connects different tissues or […] Connective tissue is the tissue that connects, separates and supports all other types of tissues in the body. anatomy-and-physiology; 0 Answers. According to my testbook. See more. A) Fascia B) Fibroblasts C) Melanocytes D) Collagen. Connective tissue of the skin is developed from _____ asked Sep 21, 2015 in Anatomy & Physiology by biologist. Start studying Connective tissue. Connective Tissue. What are the seven major types of connective tissue?6. Mixed connective tissue disease can occur in people of any age. Mixed connective tissue disease commonly abbreviated as MCTD, is an autoimmune disease characterized by the presence of elevated blood levels of a specific autoantibody, now called anti-U1 ribonucleoprotein (RNP) together with a mix of symptoms of systemic lupus erythematosus (SLE), scleroderma, and polymyositis. The exception is is the head where connective tissue may be neural crest derived (neuroectoderm). Information and translations of connective tissue in the most comprehensive dictionary definitions resource on the web. Dense connective tissue appears in two forms: dense irregular and dense regular connective tissue. All connective tissues derive from the mesodermal layer of the embryo (see Figure 4.3). Epithelial Tissue: Epithelial tissue serves as a barrier over microorganisms and dehydration while secreting excreting and absorbing substances. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Blood Capillaries Blood also serves to connect other organ systems together by supplying them with nutrients and transporting signal molecules between cells. Irregularly arranged connective tissue with fibers that are irregularly interwoven may be loose (areolar) or dense. 0 votes.
