What is Pathophysiology?
The study of abnormalities in physiologic functioning of living beings. it is in terms of common presentations of

What is the difference between clinical manifestation, complication, sequela?
Clinical manifestations- can either be objective (physician) or subjective (patient) information
Complication- a new or separate process that may arise secondarily b/c of some change produced by the original problem.
Sequela- a condition or conditions caused by and following a disease
Define pathogenesis
the manner of development of a disease
prodromal stage
early sign of a developing condition or disease
primary prevention
prevent onset of disease
secondary prevention
reduce the number of new or severe cases of a disease
incubation period
time between infection and onset of symptoms
latent period
time between exposure of tissue to injuries and first appearance of signs and symptoms.
epidemiologist
study and analysis of distribution, patterns and determinants of health and disease conditions in defined populations
endemic
constant presence in a community and changed little from year to year
epidemic
significant increase in certain population (corona virus)
pandemic
epidemic that has spread to large geographic area
fight or flight symptoms
Eyes will dilate and BP and heart rate will increase
The alarm stage; because it provides a surge of energy and physical alterations to either evade or confront danger. (when the hypothalamus senses a need to activate the GAS in response to a stimulus, a stressor placing the balance of homeostasis at risk)
Selye gas syndrome and what are the phases of GAS and what is happening in those phases?
General Adaptation Syndrome (GAS) (Selye)
-Three stages: Alarm, resistance/adaption, and exhaustion
-Alarm stage: fight-or-flight response as the result of stressful stimulus
-Hypothalamic-pituitary-adrenal (HPA) axis
-Resistance/adaptation: activity of the nervous and endocrine systems in returning the body to homeostasis
-Allostatic state: activity of various systems attempting to restore homeostasis
Exhaustion: point where body can no longer return to homeostasis
-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 [Show Less]
