Radiographic pathology Exam 1
Pathology correct answers Study of disease processes
Etiology correct answers Study of the causes of a disease
Idiopathic correct answers Disease of unknown cause
Pathogenesis correct answers Sequence of events that leads from cause of a disease,
to abnormalities, & finally manifestations
Manifestations correct answers Observed changes in the pt that are caused by the
disease (signs, symptoms, & syndrome)
Symptom correct answers Pt's perception of the disease
Signs correct answers Objective manifestations that are physically observed by the
health care professional
Syndrome correct answers Cluster of findings that characterize a specific abnormal
disturbance
Disease correct answers A specific illness or disorder characterized by a recognizable
set of signs & symptoms
Frequency, incidence, prevalence, morbidity rate, & mortality rate correct answers How
are disease processes measured?
Frequency correct answers Rate of occurrence of a pathologic process that is
measured over a given period of time, normally 1 yr
Incidence correct answers Number of newly diagnosed cases of a disease in 1 yr.
Prevalence correct answers Number of people who have any given disease at any
given point in time
Morbidity rate correct answers Ratio of sick to well persons in a given area
Mortality rate correct answers Ratio of actual deaths to expected deaths
Structural- organic disease & functional disease correct answers Name 2 classifications
of diseases.
, Structural- organic disease correct answers Involves physical & biochemical changes
within a cell
Functional disease correct answers Diseases in which the function of the organ may be
impaired, but it structural elements are unchanged
Endogenous/vascular correct answers Vascular insufficiency is the leading internal
cause of structural dz; results in tissue narcosis due to anoxia
Ischemia correct answers Deficiency of oxygen & nutrient rich blood to muscle
Infarct correct answers Necrotic tissue- ischemic necrosis
Acute injury correct answers Sudden onset, severe, but short-lived
Hypoxia correct answers Reduced oxygen supply to tissues
Anoxia correct answers Lack of oxygen, leading to necrosis
Thrombus/embolus correct answers Stationary clot; Mobile clot
Chronic injury correct answers Injury that has been present for a while & recurs
Atrophy correct answers Progressive wasting away of any part of the body, causing
impairment or loss of function
Senile, disuse, pressure, & endocrine correct answers Name 4 types of chronic
atrophies?
Hyperplasia, hypertrophy, metaplasia, dysplasia, & neoplasia correct answers Name
disturbances of cellular growth.
Hyperplasia correct answers Increase in cell #s due to an exaggerated response to
some form of stimuli
Hypertrophy correct answers Increase in cell sz
Muscles in response to increased workload correct answers Give example of
hypertrophy.
Metaplasia correct answers When a normal cell becomes abnormal in response to
cellular stress
Dysplasia correct answers Abnormal development of tissue characterized by loss of
normal uniformity of tissue
