  1. Stress impacts self and caring for others
  2. Stress as a stimulus for disease
    Cells are not static, the goal is adaptation (homeostasis) otherwise you move toward injured or diseased cell

    its on a continuous level

    physiology (health)
    pathophysiology (disease)
    • Health: normal cell......adapted cell
    • Compensatory mechanisms; cell remains intact


    • Disease: injured or diseased cell.....dead cell
    • Pathophysiologic mechanisms; loss of cell integrity
  3. Stress as a stimulus for disease

    At the center you have the "processing of information and matter"
    surrounding that you have internal and environment and surrounding that you have external and environment

    they are interconnected whether it be a cell or humans beings

    What happens externally impacts us internally and what happens internally impacts us externally.
  4. Classification of stressors
    • -Physiological - temperature, nutritional deficit,starvation, disease, illness¬†
    • -Psychological - positive & negative milestones in a person's life, marriage, pregnancy, loss of a loved one
