After depolarization, the change in membrane potential triggers voltage-gated potassium channels to open. Due to the electrochemical gradient for potassium, potassium rushes out of the cell.

Get an overview of cell depolarization in our informative video lesson. Learn its properties and how it differs from repolarization, then take a quiz to review.

Learn about action potential and how to draw an action potential graph with depolarization and repolarization points. Understand what happens during depolarization.

Polarization in Neurons: At rest, a typical neuron has a resting membrane potential of approximately -70 mV. The term depolarization refers to a change in the neuronal membrane potential that makes it …

Understand what depolarization is. Explore the meaning of cell depolarization and repolarization, and also see the difference between depolarization and repolarization. When the Na-channels of an axon …

Learn about action potential and how to draw an action potential graph with depolarization and repolarization points. Understand what happens...

The initial depolarization associated with action potential is the consequence of the opening of at the axon hillock. A. voltage-gated calcium channels B. voltage-gated potassium channels C. voltage …

Depolarization: Depolarization of a neuron occurs when a stimulus causes the threshold potential of the neuron's membrane to be reached, producing an action potential in the process. Depolarization …

The initial depolarization was strong enough that enough voltage-gated sodium channels opened to cause more o Describe how the following stages occur in a neuron in terms of ion movement across …

During an action potential, depolarization of a muscle cell occurs because a) more sodium ions diffuse into the cell than potassium ions diffuse out of it. b) the inactivation gates of the voltage-gated …
