Question # 4: Match the arrows in this illustration to the features that they describe. A is the transverse arch. B is the lateral longitudinal arch, and C is the medial longitudinal arch. I had this answer in the first place but it wouldn’t save when I tried to submit my exam. I use a wireless internet and I know you said you had problems with the people who used wireless internet and saving certain questions. Question # 5: Which three of the following are normally found as common constituents of osseous tissue? The three that are normally found as common constituents of osseous tissue would be calcium phosphate, calcium carbonate, and collagen. The reason that these are found normally is because these fibers then become encrusted with minerals-especially calcium phosphates-that harden the matrix. Calcium phosphate crystals do not form unless the product of calcium and phosphate concentration in the tissue fluids, represented reaches a critical value called the solubility product. Question # 7: Match the following terms to their proper descriptions. The epimysium is the outermost connective tissue sheet surrounding muscle. The perimysium is the middle level of connective tissue sheets surrounding muscle fascicles. The endomysium is the innermost connective tissue sheets surrounding muscle cells. Question # 10: Which 2 of the following organelles should be more abundant in osteoclasts than other bone cells?

I got one of the two answers correct. The answer I could correct was the nuclei. The other answer would be the lysosomes. The reason that these two organelles should be more abundant in osteoclasts than other bone cells is because each osteoclast is formed by the fusion of several stem cells, so osteoclasts are unusually large cells. They typically have 3 or 4 nuclei, but sometimes up to 50, each contributed by one stem cell. One side of the osteoclast, facing the bone surface, has a ruffled border with many deep infoldings of the plasma membrane. Question # 12: Arrange the following in the proper order from deepest (1) to most superficial (4). The endomysium is the deepest so that would be number 1. The perimysium is the 2 nd deepest so that would be 2. The epimysium is the 3 rd deepest or the 2 nd most superficial which would make that 3. The deep fascia is the most superficial so that would be 4. Question # 15: Which 3 of these compounds that can be absorbed through the skin are toxic to the body?
