C)depolarized.
D)hypopolarized.

Question

Quizplus · Accepted Answer

When a neuron becomes hyperpolarized, the membrane potential becomes more negative than the resting potential. This makes it less likely for the neuron to fire an action potential since it requires more stimulation to reach the threshold for firing. Conversely, depolarization can increase the likelihood of firing by bringing the membrane potential closer to the threshold. Repolarization refers to the restoration of the resting potential after depolarization, and hypopolarization is not a term commonly used in neuroscience.
