A drug that blocks Na+ channels in neurons does so not only in the axon but also in the dendrites and cell body. What overall effect would this have on action potential generation?

Mark the following statements as true or false. If a statement is false, correct it to make a true statement.

d. A depolarization is a change in membrane potential that makes the potential less negative.

Mark the following statements as true or false. If a statement is false, correct it to make a true statement.

e. A local potential is a change in membrane potential that conducts the long-distance signals of the nervous system.

What would happen if the drug blocked K+ channels instead?

A neuron's membrane potential goes from -90 mV to -10 mV. Which of the following terms describes this change?
