A) hyperpolarization.
B) depolarization.
C) an action potential.
D) saltatory conduction.

Question

Quizplus · Accepted Answer

A change in the membrane potential from -65 mV to -70 mV represents a more negative membrane potential, which is referred to as hyperpolarization. Depolarization refers to a change in the membrane potential towards a more positive value, while an action potential is a rapid depolarization and repolarization of the membrane potential. Saltatory conduction refers to the process by which action potentials are propagated along myelinated axons, jumping from one node of Ranvier to the next.
