What is the stage in an action potential that immediately follow depolarisation?
After depolarization repolarization occur whcih then again lead to resting potentiol
Why don't the terms depolarization and action potential mean the same thing?
Depolarization occurs when a stimulus opens sodium channels which allow more sodium to go into the membrane making it less negative and more positive (toward reaching threshold). An action potential can only occur once the membrane reaches threshold which means it has reached the level needed through depolarization. An action potential is a brief reversal in polarity of the membrane making the inside more positive and the outside more negative, the reverse occurs again once the membrane reaches resting potential.
What transmission of the depolarization wave along the neurons membrane?

What change in membrane potential triggers action potential?
depolarization
What transmission of the depolarization wave along the neurons membrane?
Action potential
Which is the first step in a neuron production of an action potential?
Depolarization is the first event in action potential. During depolarization, the sodium gates open and the membrane depolarizes.
What change in membrane potential depolarization or hyperpolarization triggers an action potential?
despolarization
The stage in an action potential that immediately follows depolarization is?
repolarization
The depolarization of a neural membrane creates a?
Action potentialaction potential
What happens in the neurolemma as the result of an action potential?
It provides insulation to the axons and dendrites during depolarization or action potential.
How are potential and action potential related?
Resting potential and action potential are both names for the measure of electrical voltage within the membrane of a cell. Specifically, these terms are used in describing the transfer of information along neural pathways. Resting potential is a state where cells are at rest. However, if an electrical response or depolarization reaches threshold, then ion channels open, allowing sodium ions to rush into the membrane and increase the voltage measure, firing an action potential along the length of this membrane.
When the neuron is sussiciently stimulated this process and triggers the action potential?
depolarization
