Answer:
Answer is depolarize.
Explanation:
Depolarization is one of the four stages of action potential. Other stages are hypopolarization, repolarization and hyperpolarization.
Action potential is known to occur when different ions are able to cross neuron membranes.
Depolarization occurs when the charge across a cell membrane is reversed.
It should be noted that, stimulation of other neurons or sensory receptors must have occurred before depolarization.
The nerve impulses in the nerve fibers of muscle are considered as one of the examples of action potential.
