at rest (-70 mv) the electrical force of na+ wants to move na+ .... the cell.
Homework Answers
At rest exterior of cell show more positive charge and inside is negative. So at rest electrical force of na+ wants to move na+ inside the cell.
Add Answer to:

The resting membrane potential of a neuronal axon is -70 mV. When an action potential is triggered, Na+ ions move into the axon, which reverses the voltage, bringing it towards 0 mV. Which of the following is the correct term for this sequence of events? a. Repolarization b. Hyperpolarization c. Depolarization d. Hypopolarization e. Isopolarization
