Action Potential Diagram Steps. Describe the events that lead to the generation of a nerve impulse. Learn vocabulary terms and more with flashcards games and other study tools.
The inside of the cell becomes positively charged and the outside becomes negatively charged. Action potential curve and phases diagram hypopolarization is the initial increase of the. Action potential the brief about one thousandth of a second reversal of electric polarization of the membrane of a nerve cell neuron or muscle cell.
The process involves several steps.
More gated ion channels open allowing more na ions inside the cell and the cell depolarizes so that the charges across the membrane completely reverse. If the signal is strong enough and the voltage reaches a threshold it triggers the action potential. When a neuron is inactive just waiting for a nerve impulse to come along the neuron is polarized that is the cytoplasm inside the cell has a negative electrical charge and the fluid outside the cell has a positive charge. Action potential curve and phases diagram hypopolarization is the initial increase of the.
