Describe a resting nerve cell membrane, sodium-potassium pump, action potential and what wil happen if sodium channels were blocked.
1. Clarify briefly what it means when a nerve cell is resting.
2. Explain sodium-potassium pump.
3. Assume that a membrane is at resting potential and a stimulus is received thereby triggering an impulse. Describe briefly what would (or would not) happen if the passive Na+ channels were blocked and only passive K+ channels remained open.
4. Classify the term action potential.
