membrane potential- what is it?

membrane potential is but the negative electrical charge inside the cell brought about by the difference in ionic concentration in and out of the cell. This again is due to the selective permeability of the membrane to these ions.

principle of diffusion

How molecules distribute itself in microcirculation. Transfer of substances in three compartments: intracellualry and extracellularly( interstitial and intravascularly).

what creates the pressure? It is kinetic motion of of particles that exert the pressure as it collide against each other in a give compartment. Watch and answere some questions

sodium pump - an electrogenic pump

find out how sodium potassium pump restore normal resting electrical gradient of the cell membrane after an action potential. Note the disparity in the number of ions it transport in and out of the cell. The net result is restoring the ionic and electrical gradient in the membrane.
