At resting potential, the refractory period, during which the neuron is incapable of triggering another action potential due to the sodium channels'inability to open.
42.
Maintenance of the resting potential can be metabolically costly for a cell because of its requirement for active pumping of ions to counteract losses due to leakage channels.
43.
In contrast, only slow signals from the distal dendrites are efficiently transferred to the soma, suggesting a modulatory role on the resting potential of the cell.
44.
There are many mechanisms by which a cell can establish a resting potential, however there is a typical pattern of generating this resting potential that many cells follow.

46.
In such cells, the resting potential value correlates with the degree of differentiation : undifferentiated cells in some cases may not show any transmembrane voltage difference at all.
47.
With the Na + channel no longer contributing to the membrane potential, the potential decreases back to its resting potential as the neuron repolarizes and subsequently hyperpolarizes itself.
48.
As various drugs and other factors act on the resting potential and bring it closer to the threshold potential, an action potential is more easily and rapidly obtained.
49.
If the stimulation ceases, the neuron will revert to its original resting potential as the ion channels and pumps have ample time to recover from the last stimulus.
50.
Potassium ions continue to move out of the axon so much so that the resting potential is exceeded and the new cell potential becomes more negative than the resting potential.
