Exam Questions and Answers with Complete
Content Coverage | Grade A+
• Risk -✓✓Factor that when present increases the chance of disease
Not stressors, but conditions or situations that increase the likelihood of
encountering a stressor
• Prevalence -✓✓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 -✓✓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 -✓✓The quantitative relation between two amounts showing the number of
times one value contains or is contained within the other.
• Primary Prevention -✓✓Altering susceptibility or reducing exposure for
susceptible persons
*Both illness and disease are absent
,example: vaccinations, healthy lifestyles
• Secondary Prevention -✓✓Early detection, screening, and management of
disease
*Illness absent, disease present
example: screenings and testings
• Tertiary Prevention -✓✓Rehabilitation, supportive care, reducing disability, and
restoring effective functioning
*Both illness and disease present
example: education
• Epidemiology -✓✓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 -✓✓A disease theat is native to a local region
• Epidemic -✓✓When a disease is disseninated to many individals at the same
time
(spread to many people at the same time)
• Pandemic -✓✓Epidemics that affect large geographic regions, perhaps spreading
worldwide.
(spread to large geographic areas)
,• *Chapter 2: Homeostasis and Adaptive Responses to Stressors* -✓✓
• Homeostasis -✓✓A state of being in which all systems are in balance around a
articular ideal "set-point"
• Exhausation -✓✓Point where body can no longer return to homeostasis
following a prolonged exposure to noxious agents
• Allostatic Overload -✓✓"Cost" of body's organs and tissues for an excessive or
ineffectively regulated allostatic response; effect of "wear and tear" on the body
• Adaptation -✓✓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 -✓✓Includes alterations in responsiveness to homeostatic pressures,
sensory stimuli and emotional reactivity, and to changes in motor activity
• Function of Cortisol -✓✓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* -✓✓
• Endocrine Communication -✓✓Hormones traveling in the bloodstream
Long range signaling
• Neurocrine Communication -✓✓Neurons firing information through synapses
Signals travel a very small distance between neuron and target cell
• Paracrine Communcation -✓✓Signaling through the extraceullar fluid between
cells in a tissue
Localized areas of communication
• Autocrine Communcation -✓✓Localized signaling in which the secreting cell is
also the target cell
Feedback to self
• Describe an Action Potential -✓✓Rapid, self-propagating electrical excitations
of the membrane
Mediated by voltage-gated ion channels that open (sodium flows into the cell) and
close in response to voltage changes across the membrane
Triggered by membrane depolarization
