UPDATE!!!||
A loss of proteins, such as albumin, from the plasma(as seen in
kidney and liver diseases) will result in - ANSWER-a decrease in
plasma oncotic pressure
C3a is capable of inducing degranulation of mast cells and rapidly
inducing an increase in vasodilation and increased capillary
permability, this is an: - ANSWER-anaphylotoxin
The ion that is best represented by the following concentrations,
150 mm extracellular an 15mm intracellular is - ANSWER-Na+
How much of the water foudn in our bodies is intracellular -
ANSWER-two/thirds
A keloid is - ANSWER-a hypertrophic scar that extends well
beyond the initial wound.

A lowering of blood ph due to an increase in blood levels of keto
acids such as found in diabetic ketoacidosis would be an example
of - ANSWER-metabolic acidosis
Hypotonic hyponatremeia will have all the following effects
EXCEPT - ANSWER-increased blood pressure/volume
Ph can have a significant impact on the effectiveness of local
anesthetics because the ph will help determine how much of the
local anesthetic is in a charged or uncharged state - ANSWER-
true
A loss of proteins, such as albumin, from the plasma (as seen in
kidney and liver diseases) will result in - ANSWER-a shift of fluid
from the plasma to the interstitial fluid
Alkalosis has the effect of decreasing ionized ca++concentration
in the blood as it becomes bound to the plasma proteins more
frequently (due to less H+ binding of those) this will result in
clinical signs of - ANSWER-increased neuromuscular excitability
,3|Page
Movement of potassium down its electrochemical gradient will
result in what effect on membrane potential - ANSWER-
hyperpolarization
A stronger stimulus will result in a greater membrane
depolarizaton of a neuron resulting in - ANSWER-more frequent
action potentials
All of the following are true regarding graded potential except -
ANSWER-they all look alike( in amplitude)
A stroke affecting the temporal lobe is most likely to show signs
and symptoms affecting the - ANSWER-patients speech or
hearing
The frontal lobe is responsible for concious - ANSWER-control of
voluntary motor area and limbic system
, 4|Page
The cerebellum is most responsible for - ANSWER-Control of fine
motor control and balance/posture
Infants are at greater risk of dehydrations because they relative to
adults have - ANSWER-greater surface area and higher
percentage of body weight is water
Interstitial fluid would be considered ______ Fluid - ANSWER-
extracellular
The fluid exchange between the arterial end and venous end of a
capillary bed in tissues such as muscle and skin result in all of the
fluid that leaked out of the capillary tissue being retained within
the vessels with no net loss of fluid - ANSWER-false
Chloride ion Cl- has an equilibrium potential nearly the same as
the resting potential. As a result, at resting membrane potential
chloride ion (when permeable to the membrane) will move -
ANSWER-equally in both directions
