1) During a hyperpolarization of the cellular membrane, the bulk (volume) electrolytic in the cytoplasm:
 

2) At the resting membrane potential of a typical neuronal cell, the values of electrical driving forces for
potassium and sodium ions are approximately:
 

3) Considering a continuous flow of and ideal fluid through a cylindrical vessel, indicate how will change the
velocity of the fluid flow if the vessel’s radius is increased 3 times (Assume that the pressure indicating
the flow does not change):
 

4) If we measure for the sake of experiment, the aterial blood pressure to a subject in the standing position
while the cuff is placed on the calf then the measured values of systolic/diastolic pressures will read:
 

6) When a viscous fluid is transported through a cylindrical vessel of constant diameter and under a constant
pressure, the fluid velocity:
 

7) The diameter of a cylindrical artery transporting a viscous fluid (blood) was reduced due to the growth of
an atherosclerotic plaque to 25% of its physiological value. Indicate a true sentence
 

8) The velocity of propagation of the pulse wave along the arterial vessels is:
 

10) Indicate correct concept of the voltage-calmp technique
