*Chapter 1: Introduction to Pathophysiology
Risk - Answer✔✔-Factor that when present increases the chance of disease
Not stressors, but conditions or situations that increase the likelihood of
encountering a stressor
Prevalence - Answer✔✔-A measure of disease that allows us to determine a
person's likelihood of having a disease. Therefore, the number of prevalent
cases is the total number of cases of disease existing in a population. A
prevalence rate is the total number of cases of a disease existing in a
population divided by the total population
Indicates how widespread the disease is
Incidence - Answer✔✔-A measure of disease that allows us to determine a
person's probability of being diagnosed with a disease during a given period of
time. Therefore, incidence is the number of newly diagnosed cases of a
,disease. An incidence rate is the number of new cases of a disease divided by
the number of persons at risk for the disease.
Conveys information about the risk of contracting the disease.
Ratio - Answer✔✔-The quantitative relation between two amounts showing
the number of times one value contains or is contained within the other.
Primary Prevention - Answer✔✔-Altering susceptibility or reducing exposure
for susceptible persons
*Both illness and disease are absent
example: vaccinations, healthy lifestyles
Secondary Prevention - Answer✔✔-Early detection, screening, and
management of disease
*Illness absent, disease present
example: screenings and testings
Tertiary Prevention - Answer✔✔-Rehabilitation, supportive care, reducing
disability, and restoring effective functioning
*Both illness and disease present
example: education
,Epidemiology - Answer✔✔-study of the patterns of disease involving
populations; examining the occurrence, incidence, prevalence, transmission,
and distribution of diseases in large groups of populations/people
Endemic - Answer✔✔-A disease theat is native to a local region
Epidemic - Answer✔✔-When a disease is disseninated to many individals at
the same time
(spread to many people at the same time)
Pandemic - Answer✔✔-Epidemics that affect large geographic regions, perhaps
spreading worldwide.
(spread to large geographic areas)
*Chapter 2: Homeostasis and Adaptive Responses to Stressors* - Answer✔✔-
Homeostasis - Answer✔✔-A state of being in which all systems are in balance
around a articular ideal "set-point"
Exhausation - Answer✔✔-Point where body can no longer return to
homeostasis following a prolonged exposure to noxious agents
Allostatic Overload - Answer✔✔-"Cost" of body's organs and tissues for an
excessive or ineffectively regulated allostatic response; effect of "wear and
tear" on the body
, Adaptation - Answer✔✔-Adaptation: biopsychosocial process of change in
response to new or altered circumstances, internal or external in origin
Coping: behavioral adaptive response to a stressor using culturally based
coping mechanisms
Adaptation and coping: terms used interchangeably
Arousal - Answer✔✔-Includes alterations in responsiveness to homeostatic
pressures, sensory stimuli and emotional reactivity, and to changes in motor
activity
Function of Cortisol - Answer✔✔-Primary glucocorticoid
Affects protein metabolism
Promotes appetite and food-seeking behaviors
Has anti-inflammatory effects
Chemical mediator in the inflammation response of the body
Adrenal corticosteroid critical to maintenance of homeostasis
May synergize or antagonize effects of catecholamines
*Chapter 3: Cell Structure and Function* - Answer✔✔-
Endocrine Communication - Answer✔✔-Hormones traveling in the
bloodstream
Long range signaling
