| 11. | It gradually returns to resting potential and is ready for another action potential to occur.
|
| 12. | Without this negative resting potential, cardiac cells cannot repolarize ( prepare for their next contraction ).
|
| 13. | After a cell has established a resting potential, that cell has the capacity to undergo depolarization.
|
| 14. | On the other hand, the high resting potential in undifferentiated cells can be a metabolic advantage.
|
| 15. | They are always very close to their respective concentrations when the membrane is at their resting potential.
|
| 16. | Stretching GI muscles can affect the resting potentials of ICC and affect the frequency of pacemaker activity.
|
| 17. | Such effects include nerve synapses and cardiac beat as well as the resting potential of a somatic cell.
|
| 18. | As a result, the difference between resting potential and threshold potential is increased and firing is less likely.
|
| 19. | The resting potential prior to the action potential is typically " 90mV, somewhat more negative than typical neurons.
|
| 20. | As potassium moves out of the cell the potential within the cell plummets and approaches its resting potential once more.
