action potential
In neuroscience, another name for an action potential is a nerve impulse.
It is probably called as action potential.
Its main function is to propagate the action potential (the 'impulse') along the length of the axon.
electrical wave conducted along the nerve generated by the voltage difference across the cell membrane of the nerve cells.
Neuron has to be stimulated to the point of it's threshold in order for an action potential to be initiated and transmitted
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 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.
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).
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
An electrical signal traveling along a nerve is called a nerve impulse or action potential.
