What happens during depolarization and repolarization? During depolarization the cell becomes less negative due to positive charges entering the cell. Get an overview of cell depolarization in our informative video lesson.
Learn about action potential and how to draw an action potential graph with depolarization and repolarization points. Understand what happens during depolarization. Explore the meaning of cell depolarization and repolarization, and also see the difference between depolarization and repolarization.
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. 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. The initial depolarization associated with action potential is the consequence of the opening of at the axon hillock.
A) ventricular repolarization b) atrial repolarization c) atrial depolarization d) ventricular depolarization 1.
