  3. Disease
    The interruption cessation or disorder of a body system or organ structure
  4. Etiology
    Causes of disease are etiological factors, (biological physical forces Chemical agents or nutritional)
  5. Pathogenesis
    Sequence of cellular/tissue events that take place from initial contact with etiological agent until disease expression
  6. Morphology
    Structure or form of cells, morphogenic changes: gross. Atomic and microscopic changes characteristic of a disease
  7. Clinical manifestations
    The manifestations produced by condition that make it evident that a person is sick. the signs and symptoms
  8. Signs

    Developed to explain spread of infectious disease during epidemics, emerged as a science to study risk factors of multispectral diseases i.e. heart disease
  13. Epidemiologic studies
    Looks for patterns, characteristics (race, age, lifestyle, habitats) in persons affected with a particular disorder
  14. Epidemiologic methods
    Are used in research studies to determine the natural history of the disease, how it spreads, and how to prevent, Control and eliminate need it.
  15. Reliability
    The extent to which an observation, when repeated, gives the same result
  16. Validity
    The extent to which a measurement tool measures what it is intended to measure
  17. Sensitivity
    The proportion of people with a disease who test positive on the test for that disease did test positive on the test that disease, "true positive", it's a sensitive test is negative that needs the disease has been excluded, ruled out

    If the test is highly sensitive and a test result is negative you can be nearly certainly don't have the disease. Sensitivity test helps rule out disease
