... [Show More] successfully adapt to challenges. Intricate regulatory processes orchestrated by the brain.
Epidemiology:
Study of diseases within a population. Epidemiology is the method used to find the causes of health outcomes and diseases in populations.
Review the different levels of disease prevention such as primary, secondary, and tertiary as well as examples for each.
o primary: Altering susceptibility or reducing exposure for susceptible person (Example: Immunization)
o secondary: Early detection screening, and management of disease. (Example: cancer screening, performing months breast examinations)
o tertiary: Rehabilitation, supportive care, reducing disability, and restoring effective functioning. (Example: PT/OT following stroke)
Review the differences between the sympathetic vs the parasympathetic nervous systems.
o Sympathetic: Fight or Flight response
o Parasympathetic: Rest and digest
What happens to the body during "fight-or-flight" response?
o Body focuses on specific organs and tissue to survive until body alleviates itself from stressor
§ Dilate pupils

What is a hypersensitivity? Review the four different types of hypersensitivities:
Antigenic response beyond what is considered normal
Response to antigens (allergens) leading to damage:
Type I :Anaphylaxtic
Type II: Cytotoxic
Type III: Immune complex hypersensitivity
Type Iv: Delayed cell mediated
Review the difference between active and passive immunity, know examples for each type.
o Active immunity: When the body creates antibodies when coming into contact with a virus. Ex: Vaccination
o Passive immunity: Passing on antigens. Ex: Breast feeding
Review the difference between active and passive immunity, know examples for each type.
vActive - when the body creates a antibodies once coming into contact with specific virus
Passive - when passed from mother to child through breast milk or blood stream [Show Less]
