Which of the following actions would depolarize a neuron?

Question

Quizplus · Accepted Answer

Neuron depolarization occurs when there is an influx of positively charged ions, typically sodium, into the cell. Therefore, increasing membrane permeability to sodium would allow more of these ions to enter the cell and depolarize the neuron. The other choices would not cause depolarization, as decreasing membrane permeability to sodium or calcium would reduce the flow of positively charged ions into the cell, and increasing membrane permeability to potassium would lead to efflux of positively charged ions out of the cell, thus making the cell more negative and hyperpolarized.
