QUESTION: List 2 differences between benign and malignant neoplasms. - ANSWER-Any
combination of the following - Benign tumors are well-differentiated cells, resemble the cells of
tissues of origin, and have a slow, progressive rate of growth. They grow by expansion and
, Page 2 of 41
remain localized to their site of origin, not capable of metastasizing. Malignant neoplasms
invade and destroy tissue. They grow rapidly, spread to other parts of the body, and lack well-
defined margins. They can compress blood vessels and outgrow their blood supply, causing
ischemia and tissue injury.
QUESTION: Compare and contrast the two types of gangrenous necrosis. - ANSWER-In dry
gangrene the affected tissue becomes dry and shrinks, the skin wrinkles, and its color changes
to dark brown or black. The spread of dry gangrene is slow. It results from a cut-off in arterial
blood supply and is a form of coagulation necrosis. In wet gangrene, the affected area is cold,
swollen, and pulseless. The skin is moist, black, and under tension. Blebs form on the surface,
liquefaction occurs, and a foul odor is caused by bacterial action. The spread of tissue damage is
rapid.

a way that minimizes risk of fractures is the key. Exercises done safely as an answer should
receive full credit.)
QUESTION: True/False: Cell proliferation is the process in which proliferating cells become more
specialized cell types. - ANSWER-False, cell differentiation
QUESTION: True/False: Cell differentiation is the process of increasing cell numbers by mitotic
cell division. - ANSWER-False, cell proliferation
Taking your child to the pediatrician for their annual well check-up and keeping up with the
recommended vaccination schedule would be an example of: - ANSWER-Primary prevention
