| Q. |
What is the relatively static membrane potential of quiescent cells called? |
| A. | half-cell potential |
| B. | action potential |
| C. | resting membrane potential |
| D. | cell potential |
| Answer» C. resting membrane potential | |
| Explanation: Resting membrane potential or the resting potential is the relative static membrane potential of quiescent cell. That is if the resting membrane potential of a neuron is about -70 mV (mV=millivolt) it means that the inside of the neuron is 70 mV less than the outside of the neuron. An action potential occurs when the potential of the membrane of a given axonal position increases and decreases rapidly. This depolarization causes depolarization of adjacent positions in a similar way. | |
