Yes, an action potential is needed for a nerve impulse to occur.
What else can I help you with?
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
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).
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.
Where is the area a nerve impulse is generated?
A nerve impulse is generated at the axon hillock of a neuron, which is the region where the axon meets the cell body. This area contains a high concentration of voltage-gated sodium channels, allowing for the rapid depolarization necessary to initiate an action potential when the membrane potential reaches a certain threshold. Once generated, the impulse travels along the axon toward the synaptic terminals.
When the what reaches the end of the axon the neurotransmitter is released?
When the _____________reaches the ends of the axon the neurotransmitter is released and it diffuses to the muscle cell membrane to combine with receptors there?Sarcolemma
