  8. What is pathogenesis? (ch 1)
    The sequence of cellular and tissue events that take place from the time of initial contact with an etiologic agent until the ultimate expression of a disease.

    A pathologic or traumatic discontinuity of a body organ or tissue.
  13. Signs and symptoms are terms that describe what? (ch 1)

    • pain
    • difficulty breathing
    • dizziness
  17. What is a syndrome? (ch 1)
    A compilation of signs & symptoms that are characteristic of a specific disease state.
  18. What are sequelae? (ch 1)
    Lesions or impairments that follow or are caused by a disease. (p. 5)
  19. What is a diagnosis? (ch 1)
    The designation as to the nature or cause of a health problem.

  21. During the ______ stage, the disease is not clinically evident but is destined to progress to clinical disease. (ch 1)
    preclinical
  22. What is epidemiology? (ch 1)
    the study of disease occurrence in human populations.
  23. What type of person is more concerned with whether smoking itself is related to cardiovascular disease and whether the risk of heart disease decreases when smoking ceases? (ch 1)
    an epidemiologist
  24. Who would be concerned about the causative agent in cigarette smoke and the pathway by which it contributes to heart disease? (ch 1)
    a biomedical researcher
  25. _______ are used to determine how a disease is spread, how to control it, how to prevent it, and how to eliminate it. (ch 1)
    epidemiological methods
  26. ______ disease is not clinically apparent and is not destined to become clinically apparent. (ch 1)
    subclinical
  27. What is morbidity? (ch 1)
    The effects an illness has on a person's life.
  28. These hormone produces a decrease in insulin release and an increase in glucagon release. (ch 9, p. 206)
    Catecholamines (NE, epi)
  29. These hormones cause an increase in heart rate, cardiac contractility, and vascular smooth muscle contraction; relaxation of bronchial smooth muscle. (p. 206)
    Catecholamines (NE, epi)
  30. This hormone stimulates ACTH release from the anterior pituitary and increased activity of LC neurons. (206)
    CRH (CRF)
  31. Hormone that stimulates the synthesis and release of cortisol. (206)
    ACTH
  32. Hormones that potentiate the actions of epi and glucagon inhibit the release and/or actions of the reproductive hormones and TSH; produce a decrease in immune cells and inflammatory mediators (206)
    glucocorticoids (ex=cortisol)
  33. Hormones that increase sodium absorption by the kidney. (206)
    mineralocorticoids (ex = aldosterone)
  34. Hormone that increases water absorption by the kidney; produces vasoconsriction of blood vessels; and stimulates the release of ACTH. (206)
    ADH, vasopressin
  35. What is the locus caeruleus? (206)
    An area of the brain stem that is densely populated with neurons that produce NE and is thought to be the central integrating site for the ANS response to stressful stimuli.

    • hypothalamus
    • limbic system
    • hippocampus

    • neuroendocrine
    • immune
  38. The stress response involves the activation of which physiologic systems that work in a coordinated fashion to protect the body against damage from intense demands?
    • sympathetic nervous system
    • HPA axis (hypothalamic-pituitary adrenal)
    • immune system
  39. The activation and control of the stress response are mediated by the combined efforts of what two systems?
    nervous & endocrine
  40. What is pathophysiology (ppt)?
