It provides insulation to the axons and dendrites during depolarization or action potential.
Sodium ions enter the axon during action potential. This influx of sodium ions depolarizes the axon membrane, leading to the propagation of the action potential along the axon.
The voltage-gated Na+ channels get deactivated, thus the sodium ions cannot diffuse into the cell and cause depolarisation and this also provides time for the membrane to prepare for its second action potential.
Resting potential
During the action potential, there is a depolarization phase where the cell membrane potential becomes less negative, followed by repolarization where it returns to its resting state. This involves the influx of sodium ions and efflux of potassium ions through voltage-gated channels. The action potential is a brief electrical signal that travels along the membrane of a neuron or muscle cell.
It provides insulation to the axons and dendrites during depolarization or action potential.

The consequences of the story's main events unfold.
During an action potential in a neuron, there is a rapid change in electrical charge across the cell membrane. This change allows for the transmission of signals along the neuron.
During an action potential, the neuron's electrical charge rapidly changes from negative to positive, allowing for the transmission of signals along the neuron.
The consequences of the story's main events unfold.
After an action potential is fired, the neuron goes through a refractory period where it cannot fire another action potential immediately. During this time, the neuron resets its electrical charge and prepares for the next signal.
Sodium ions enter the axon during action potential. This influx of sodium ions depolarizes the axon membrane, leading to the propagation of the action potential along the axon.
Generally, this is when the story begins to 'wrap up' but without coming to an end. No new points should be added, unless in preparation for a sequel, and the problem should start to be resolved. The consequences of the story's main events unfold.
Voltage-gated sodium channels open during the depolarization phase of an action potential, when the membrane potential becomes more positive.
The voltage-gated Na+ channels get deactivated, thus the sodium ions cannot diffuse into the cell and cause depolarisation and this also provides time for the membrane to prepare for its second action potential.
The majority of a narrative typically takes place during the rising action and climax of the plot where the conflict is developed and reaches its peak. This is where the tension and excitement in the story are at their highest, leading to the resolution and falling action.
