51)What is a simple method of telling the difference between stratified squamous epithelium and transitional epithelium? |
Answer: Stratified squamous epithelium changes cell shape from the basement membrane to the surface. At the basement membrane the cells tend to be columnar or cuboidal and flatten out as they work their way to the surface. Transitional epithelium has cells that are pretty much the same shape from the basement membrane to the surface. The surface cells are generally the largest cells. The cells change their shape according to the pressure applied. |
52)Macrophage-like cells are found in many different tissues, and may have specific names that reflect their location or specializations. What is the one functional characteristic common to all macrophage-like cells? |

Answer: transitional |
59) ________ tissue forms the framework for the lamina propria of mucous membranes. |
Answer: Areolar or loose connective: |
60) How is epithelial tissue the opposite of connective tissue? |
Answer: In epithelial tissue the cells are packed together very tightly. Epithelial tissue is avascular. Epithelial tissue has three cell types that cover or line things and make tubes. Epithelial tissue has no fibers and it tends to be polar. Connective tissue has cells spaced far apart and is highly vascular (except cartilage). The cells of connective tissue vary greatly in shape and size. Connective tissue glues other tissues together and has three fiber types. Connective tissue tends to be nonpolar. Connective tissue has a large amount of ground substance; epithelial tissue does not. |
61) Since mature adipocytes do not divide, how can adults gain weight? |
Answer: Adipocytes contain a fat-filled vacuole that can fill or empty, causing the cell to gain or lose volume. |
62) Kidney tubules are composed of ________ epithelium. |
Answer: simple cuboidal |
64) Tendon tears or breaks are difficult to repair both physiologically and surgically. Why? |
Answer: Tendons are composed of dense regular connective tissue, which consists of densely packed, parallel connective tissue fibers. This type of tissue has relatively few cells and vascular supply is poor; consequently, repair is slow. Because of the structure of the tissue, surgical repair can be compared to attempting to suture two bristle brushes together |
66) What are the primary germ layers during embryonic development and what do they ultimately produce? |
Answer: The ectoderm produces skin, the nervous system, and all tubes opening to the outside. The mesoderm produces muscles and connective tissue. The endoderm produces all internal organs. |

112)In adult humans, most cancers are carcinomas or adenocarcinomas. These include cancers of the skin, lung, colon, breast, and prostate. Which of the four basic tissue types is involved? |
Answer: Epithelium gives rise to most cancers. This is probably because epithelial cells divide more, leading to more opportunity for damage to growth control mechanisms, and because epithelia are more often in contact with environmental insults such as ultraviolet radiation and carcinogens. |
113) Explain why an open wound would need a bed of granulation tissue for wound healing to occur. |
Answer: Granulation tissue contains capillaries that grow in nearby areas and lay down a new capillary bed. This means the wound bed has a meshwork of capillaries that provide oxygen-rich blood to the wound for healing. |
114) A 6-year-old child fell off his bike and scraped his knee. Describe the first stage of wound healing. |
Answer: The first stage is the inflammatory stage, characterized by hemostasis (cessation of bleeding) and formation of blood clots and phagocytosis by leukocytes and macrophages. |
115) Without macrophages, wound healing is delayed. Why? |
Answer: Macrophages are large, irregularly shaped cells that act as key defenders that avidly phagocytize a broad variety of foreign materials, ranging from foreign molecules to entire bacteria to dust particles. This "big eater" also disposes of dead tissue cells, which helps to clean out the wound, allowing for granulation tissue to form. |
116) A 45-year-old woman is admitted to the hospital for surgical removal of a tumor on her thyroid gland. The surgeon informs her that she will have only a very small scar. How could this be possible? |
Answer: By making a thin incision, the amount of granulation (scar-forming) tissue will be minimal. As the scar tissue beneath matures and contracts, the layer of epithelium thickens and resembles the adjacent tissue. The final result may be only a fine white line |
