Chapter 11.2, Problem 1I
Summary Introduction
To describe: The changes in the neuron’s plasma membrane on membrane potential if the voltage-gated sodium ions are blocked by chemical.
Introduction: There are various types of channels present in the membrane of the neuron to induce membrane potential to action potential. The voltage-gated ion channel is one of the channels that open or close the channel according to the response of the membrane potential of the plasma membrane.

When a neuron opens voltage-gated Na+ channels, what happens to the membrane potential?
Neurons, particularly those in the brain, receive multiple excitatory and inhibitory signals. What is the name of the extension of the neuron at which such signals are received? How does the neuron integrate these signals to determine whether or not to generate an action potential?
How can only positive ions result in depolarization and repolarization of the membrane during an action potential?
