It is a difference in charge supplied by ion position. In resting potential the tendency is for the inside of the cell membrane to have a negative ionic charge, while the outside of the membrane has a positive charge. The change, back and forth in these two charge potentials is the conduction of charge down the neuron and is called the action potential.

What is another name for an action potential in neuroscience?
In neuroscience, another name for an action potential is a nerve impulse.
An electrical impulse moving down an axon is called?
This is called action potential. Action potential is the change in electrical potential that occurs between the inside and outside of a nerve or muscle fiber when it is stimulated, serving to transmit nerve signals.
What is the form of message carried by a nerve cell called?
The form of message carried by a nerve cell is called an action potential. An action potential is a brief electrical signal that travels along the nerve cell's axon, allowing for communication between different parts of the nervous system.
An electrical impulse moving down an axon is called what?
An electrical impulse moving down an axon is known as an action potential.
What is an initial segment of a nerve impulse?
Axon hillock- a pyramidal shaped region where all axons originate fromInitial segment- an area just beyond the axon hillock where all the stimulatory and inhibitory signals coming into the neuron are algebraically summed and it is decided whether or not an action potential should propagate or not.-----The above describes the structure of the axon where the action potential is created.However, the actual nerve impulse (action potential) is generated in a series of steps based on how the ion channels trigger.In this respect the first segment of the nerve impulse is the stimulus, which has to trigger positive ion influx beyond a given threshold.After that stimulus exceeds the threshold, it triggers the opening of ion channels which pump sodium ions into the axon and potassium ions out, thus increasing the net positive charge on the inside of the neuron, depolarizing it and initiating the action potential (the nerve impulse).
Is a action potential necessary for a nerve impulse to occur?
Yes, an action potential is needed for a nerve impulse to occur.
Is an action potential necessary for a nerve impulse to occur?
Yes, an action potential is needed for a nerve impulse to occur.
Also called a nerve impulse transmitted by axons?
action potential
What is another name for an action potential in neuroscience?
In neuroscience, another name for an action potential is a nerve impulse.
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 the membrane of a nerve cell is comprised of?
Its main function is to propagate the action potential (the 'impulse') along the length of the axon.
What is impulse in the nervous system?
electrical wave conducted along the nerve generated by the voltage difference across the cell membrane of the nerve cells.
What is the amount of stimulation required to intiate a nerve impulse called?
Neuron has to be stimulated to the point of it's threshold in order for an action potential to be initiated and transmitted
An electrical impulse moving down an axon is called?
This is called action potential. Action potential is the change in electrical potential that occurs between the inside and outside of a nerve or muscle fiber when it is stimulated, serving to transmit nerve signals.
A neuron transmits a nerve impulse as a wave of?
A neuron transmits a nerve impulse as a wave of electrical activity called an action potential. This action potential travels along the length of the neuron's axon and triggers the release of neurotransmitters at the synapse, allowing communication between neurons.
Why does the frog sciatic nerve give a graded response?
The frog schiatic nerve gives a graded response because the nerve is a bundle of axons and not a single axon (thus it does not show the all or none response of an axon-either generating an action potential or not). If one axon is generating an action potential then a small nerve impulse is witnessed, if all axons are simultaneously generating action potentials then a large nerve impulse is witnessed. Thus the nerve impulse is graded (it can be none, small, medium, large, larger, maximal).
Describe the path a nerve impulse travels throughout your body from stimulus to response?
Brain send the message via nerve impulses involving neurons which use the neuro-transmitter AcetylcholineAcetylcholine- a neurotransmitter released at the neuromuscular junction triggers a muscle action potential, which leads to muscle contraction
