USAHS Pathophysiology Exam 1 (Test Review Material)-USAHS Pathophysiology - Spring 2023 (Q&A)
Term for the study of normal function and it's components ✔️Ans -
Physiology
Term for the study of disease, a diseased state.
Disordered physiological processes associated with disease or injury.
✔️Ans - pathophysiology
Pathologies typically result from what type of failure? ✔️Ans -
Compensation failure
What is known as a group of signs and symptoms that occur together and
characterize a specific disorder or condition? ✔️Ans - Syndrome
A DYNAMIC STEADY STATE (not equilibrium). Required for constant
internal stability. ✔️Ans - Homeostasis
Describes the origin and development of the disease, and whether it is
acute, chronic, or recurrent. ✔️Ans - Pathogenesis
Successful compensation to internal or external changes, if not
compensated = ✔️Ans - disease
Some ways the body maintains homeostasis: To maintain hemostasis the
body monitors BP, glucose, minerals etc.. ✔️Ans - BP, glucose, minerals
etc..
theological approach is the ? key words? ✔️Ans - the WHY does it
happen;
"Because or To"
Mechanistic Approach is the? ✔️Ans - the HOW does it happen
Example of how Shape follows Function: ✔️Ans - RBC = normal
biconcave
,if sickle = anemia
Intracellular components/functions:
Who Does/Contains the Following?
- DNA ✔️Ans - Nucleus - DNA
Intracellular components/functions:
Who Does/Contains the Following?
- ATP ✔️Ans - Mitochondria - ATP
Intracellular components/functions:
Who Does/Contains the Following?
- calcium storage ✔️Ans - Smooth ER - calcium storage
Intracellular components/functions:
Who Does/Contains the Following?
- Protein modification & Packaging ✔️Ans - Golgi Apparatus - Protein
modification
Intracellular components/functions:
Who Does/Contains the Following?
- protein synthesis ✔️Ans - Rough ER - protein synthesis
The type of feedback that increases, reinforces or enhances the effects of
the variable is __________.
These types ARE NOT Homeostatic - reinforces a physiological response;
outside factor is required to shut off the loop ✔️Ans - positive feedback
loop
,What are some examples of positive feedback loop? ✔️Ans - -Blood
Pressure
-Blood clot formation
(amplifies chemicals in the clot promote further clotting UNTIL it's sealed;
NO MORE STIMULUS)
-Milk production
(as long as baby is nursing. milk will be produced UNTIL babies done; NO
MORE STIMULUS)
-Uterine contractions during childbirth
(contraction UNTIL babies out/NO MORE STIMULUS)
-*Fever*
(virus/bacteria, body heats self to get rid of it UNTIL the enemy destroyed;
NO MORE STIMULUS)
The type of feedback that stops the stimulus / variable?
These types ARE Homeostatic - prevents a physiological response ✔️Ans
- negative feedback loop
(response loop shuts off)
What are some examples of negative feedback loop? ✔️Ans -
THERMOREGULATION
Regulation of body temperature (a nervous system mechanism)
BLOOD SUGAR
Regulation of blood glucose by insulin (an endocrine -pancreas- system
mechanism)
which type of feedback requires an external que to stop? ✔️Ans -
positive feedback loop
Metabolism Terms:
, Type of reaction that NEEDS ATP; makes ATP ; Builds large from small;
releases energy
Exer or Endergonic? ✔️Ans - Anabolic
ENDERgonic
Metabolism Terms:
Type of reaction that breaks down large molecules; gives ATP (end w/ ADP
and Phosphorus); requires energy
Exer or Endergonic? ✔️Ans - Catabolic
EXERgonic
Metabolism Terms:
Short Acting w/out oxygen; doesn't require O2; strength body
building/weightlifting quick movements short acting ex: weight lifting.
✔️Ans - Anaerobic
Metabolism Terms:
Needs oxygen, for longer duration - endurance activities. Uses A LOT of
ATP. ✔️Ans - Aerobic
Metabolism Terms:
The MAIN POWER of the body; breaking down glucose in aerobic and
anaerobic means (metabolism); ends in Kreb's Cycle
(glucose to -> two 3-C pyruvates) ✔️Ans - Glycolysis
Where does glycolysis occur and how many ATP are yielded? ✔️Ans -
cytosol
2 ATP
