Radiologic Pathology: Exam 1 Test
Questions and Answers.
What to do with an additive pathology - Answer Increase technical factors
What to do with the destructive pathology? - Answer Decrease technical factors
Pathogenesis - Answer Sequence of events producing cellular changes that ultimately lead to
observable changes
Manifestations - Answer Observable physical changes
Etiology - Answer Study of the cause of a disease
Epidemiology - Answer Investigation of the disease in large groups
Diagnosis - Answer Identification of illness, typically found after signs or symptoms arise
Signs vs. Symptoms - Answer Signs are manifestations of the disease that can be detected by
a physician during an exam. Symptoms are the patient's own perception of the disease.
Incidence - Answer Number of new cases found in a given period
Prevalence - Answer Number of cases found in a given population
Morbidity - Answer Incidents of sickness, sufficient to interfere with an individuals normal
daily routine
Mortality - Answer Average number of deaths caused by a particular disease in a population
Epidemic - Answer Rapid, widespread occurrence of a disease and a large number of people
Pandemic - Answer An epidemic affecting the majority of a population of a large region or
many parts of the world
Contusion - Answer bruise
, Lesion - Answer Abnormal tissue in the body
Pseudo- - Answer false, fake
Dys- - Answer abnormal, difficult, painful
Atrophy - Answer A generalized decrease in cell size
Hypertrophy - Answer Generalized increase in cell size
Hyperplasia - Answer Increase in the number of cells in a tissue
Metaplasia - Answer Conversion of one cell type into another that is not normal for that
tissue
Dysplasia - Answer Abnormal changes occurring in mature cells
Well-differentiated cells - Answer Similar, closely resemble tissue of origin
Moderately differentiated cells - Answer Abnormal but still resemble cells in the area
Poorly differentiated cells - Answer Very abnormal, have a very small amount of time to
mature
Undifferentiated cells - Answer Look nothing like normal cells, we're not able to mature at all
Characteristics of benign tumors - Answer Slow growing, non-invasive, smooth borders, well
differentiated, localized
Characteristics of malignant tumors - Answer Fast proliferation, speculated, borders, poorly,
or undifferentiated, invasive, likely to spread
How does cancer form? - Answer Abnormal proliferation of normal cells (normal cells should
stop proliferating at a certain point). carcinogens cause mutations to occur in the cells and its
genes, which affects the growth genes
