Help me with ex 8 and 9. Thanks
Why are fibroblasts important to healing? What's the difference between scarring and regeneration? What would be an example of "ground substance"? Specialized cells? "Matrix"? Fibers? (What type of tissue are we discussing here-epithelium, connective, nerve or muscle?) Type of connective tissue: Write the name of the specific tissue next to its description: ___________ Almost all ground substance: fibers dissolved in ground substance until needed, specialized cells are very tiny and designed to carry oxygen. _____________ Ground substance is dense and highly mineralized: fibers form a collagen framework. _______ Loose: may contain adipocytes, mast cells, and widely spaced fibers. Forms lamina propria (an adhesive part of basement membrane) beneath skin. ______ Many fibers (which run in different directions): can withstand mechanical stress: found in joints and in dermis. ________ Forms skeleton of embryo (and then is replaced by bone): still most common form of cartilage: fibers not visible (but present): resilient matrix that resists compression. _________ Found in places where there would be a need for high shock absorption. _______ Least common type of cartilage-found only in a very few structures of the body. ______ A dense form of connective tissue proper-found in blood vessels and some other locations where elasticity is important for normal function. _______Fibers in this tissue all run in parallel to each other: gives this tissue a lot of strength to resist pulling forces: found associated with bones and muscles. _______ This forms the "stroma" of delicate organs such as lymph nodes and spleen provides a framework for specialized cells, particularly cells of the immune system.Explanation / Answer
8) Fibroblasts are important in wound healing because of the following reasons,
Regeneration is the restoration of tissue to its original cellular and extracellular structure. egeneration of tissues takes place in bones and liver. Repair of the organs after injury occurs by scarring. Scarring occurs as a reult of laying down of connective tissue. Scarring is not identical to any tissue in the body.
9) Fibroblasts are a type of connective tissue.
