2 Which of the following statements is TRUE regarding the nerve impulse/action potential?
When a neuron is at rest, it can fire, but only weakly. It fires pore strongly when it is at action potential.
The neuron is depolarized when it is at its resting potential. This means that ions are mixed (negative and
positive charges inside and outside of the neuron's membrane).
The neuron is polarized when it is at its resting potential. This means that ions are separated by charge
(positives outside the membrane; negatives inside the neuron).
O When a neuron reaches complete polarization, it fires.
