When repolarization of a neuron is complete, the

A) neuron dies.
B) neuron regenerates.
C) cell no longer has a potential difference across its membrane.
D) original polarity of the neuron is restored.
E) neuron is no longer excitable.

Repolarization

The process by which a neuron or muscle cell returns to its resting negative charge after depolarization.

Neuron Polarity

The structural and functional difference between the axon and dendrites of a neuron, which determines the direction of nerve impulse transmission.

Potential Difference

The difference in electric potential energy per unit charge between two points in a circuit.
