Questions And Answers

Negative feedback inhibition! Which type of control is most common in the body




Something that upsets the balance of homeostasis. Anything that represents a deviation from

some norm or steady state. Provide the definition & examples of a "stressor" as it applies

to the concept of homeostasis.




Cellular adaptation occurs if a cell is unable to maintain its original homeostatic state. In those

circumstances, it must draw upon its reserves and adapt to the new environment. This is cellular

adaption. Decline occurs when the cell cannot adapt. Compare cellular adaptation vs.

decline toward cellular dysfunction and give examples.




Hypertrophy (cells increase in size), hyperplasia, atrophy, and metaplasia What are the

four cellular adaptions?




Glucose metabolism-insulin resistance -> Type 2 Diabetes, Thermoregulation, and the Stress

Response. What three examples of homeostatic imbalance were given in class?

Questions And Answers
Shunting blood to core, shivering, increasing epinephrine and norepinephrine, increased

thyroxine for elevating metabolism, and increasing physical activity. How does the body

regain homeostasis during hypothermia?




65% What percentage of human body is water.




Intracellular compartment and Extra cellular compartment. In the ECF you have interstitial fluid

(in the cell), intravascular fluid (plasma), and cerebrospinal fluid. Body Fluid

Compartments - What are the two fluid compartments discussed in lecture?




ECF Bicarbonate ions are found in high concentrations in which fluid compartment in

neurons?




ECF: Sodium is main cation and the balancing anions are chloride and bicarbonate.




ICF: Potassium and magnesium are the major cations and proteins and organic phosphates.

Compare and contrast the ionic compositions of ECF vs. ICF in neurons. What are the

balancing anions?

Questions And Answers
ICF is more acidic than ECF. Which fluid compartment has a lower pH?




Low The ICF has a very ____ concentration of ionized Ca2+?




Phospholipids, cholesterol, glycolipids, and proteins (e.g. transporters, enzymes, hormone

receptors, antigens, ion and water channels, etc) What are the major components of a

plasma membrane? What do these components look like in the membrane?




Separates ICF from ECF What are the functions of the plasma membrane?




It makes the membrane highly permeable to lipid soluble substances (like carbon dioxide,

oxygen, fatty acids, and steroid hormones) but a very low permeable to water soluble substances

(like ions, glucose, and amino acids.) How do the chemical compositions of phospholipids

influence transport across the plasma membrane?




Uphill moves a solute against its electrochemical gradient and requires ATP. Downhill moves it

down its electrochemical gradient and does not require energy. Compare and contrast

downhill vs. uphill cell membrane transport.
