When a neuron gets excited from a neighboring cell (from neurotransmitters) it gets 'leaky' to certain ions like sodium, potassium, calcium and chloride - and in doing so its state of electrical excitability changes. If it changes by just the right amount then special proteins called 'voltage-gated ion channels' will open allowing a huge influx of even more ions (usually sodium) causing a wave of electrical charge to flow away from the cell body down its axon to its axon terminal - where it will then release its neurotransmitters.

Which part of the neuron is capable of generating an action potiental?
axon
What parts of a neuron is capable of generating a graded potential?
The dendrites portion of a neuron will generate a potential.
The anatomical region of a multipolar neuron that has the lowest threshold for generating an action potential is?
Axon hillock
What substances plays a mojor role in generating the membrane potential of a neuron?
Well, for starters, membrane potential is a separation of charges across the membrane. So i think what you mean is "generating the action potential in a neuron". So in that case The substance that plays a major role in generating an action potential is Sodium (Na+). However, if you really mean membrane potential, there is only two substances associated with that and those are sodium (Na+) and potassium (K+).However, in truth, the generation of an action potential depends on the ligand and its receptor.
Which part of the neuron is responsible for generating a nerve impulse?
Axon
A neuron will generate action potentials when it?
A neuron will generate action potential when it is stimulated by a neurotransmitter.
What substances plays the major role in generating the membrane potential of a neuron?
sodium
What do resting and action potentials depend on?
The resting and action potentials depend on the balance of charges of the area outside the neuron and inside the neuron. A resting potential is when the neuron is more negatively (approximately -70mv) charged than the area outside the neuron. The action potential occurs when sodium ions rush into the neuron, causing the polarity to be reversed. When there is no difference in charge between the area inside the neuron and the area outside the neuron, no action potentials can be started by that neuron.
What structure of a neuron is capable of propagating an electrical impulse?
the dendrites are
Why are motor neuron ofter referred to as the action cell?
it is often termed the action neuron because it tells the muscles what to do or how to react.
Which neurons decide about the action for a certain stimulus?
Sensory neuron
What causes the vesicles inside a neuron to fuse with the plasma membrane?
An action potential in the neuron
