When the neuron is sussiciently stimulated this process and triggers the action potential?
depolarization
When the neuron is sufficiently stimulated this process occurs and triggers the action potential?
depolarization
State in which the resting potential is reversed as sodium ions rush into the neuron?
Depolarization
How is the resting potential different from repolarization?
Repolarization is when the cell or neuron returns to be more negative. Depolarization is when the cell or neuron becomes less and less negative.
Why is the resting membrane potential the same value in both the sensory neuron and the interneuron?
Because it didnt have a stimulus to activate depolarization
When the neuron is sussiciently stimulated this process and triggers the action potential?
depolarization
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.
When the neuron is sufficiently stimulated this process occurs and triggers the action potential?
depolarization
State in which the resting potential is reversed as sodium ions rush into the neuron?
Depolarization
What event follow the depolarization of neuron?
Repolarization is after depolarization. It descends to a region of hyper polarization where it is more polar than resting membrane potential
How is the resting potential different from repolarization?
Repolarization is when the cell or neuron returns to be more negative. Depolarization is when the cell or neuron becomes less and less negative.

When under what conditions will a local depolarization not lead to the action potential?
If ion pumps open to hyperpolarize the neuron (chloride ions flowing into the neuron) elsewhere, leading to a net polarization/hyperpolarization, then the action potential will not be created.In order for the AP to be induced, a NET depolarization (influx of cations) must be created above the membrane threshold.
What causes Local depolarization that leads to generate action potential?
Opening of sodium channels and the fact that potassium channels are still closed leads to rapid depolarization that may lead to the neuron firing.
The abrupt shift in the charge of a neuron from a negative to a positive charge is known as?
It is probably called as action potential.
What is depolarization of a neurotransmitter?
Depolarization stimulates the release of the neuro-transmitter from the terminal end of the neuron.
