The action potential is generated when a stimulus?
When a stimulus stimulates a neuron above the threshold, the action potential is generated.
What determines if an action potential is initiated in the postsynaptic neuron?
Every time neurotransmitter is released from the presynaptic neuron it generates an excitatory post synaptic potential(EPSP) in the postsynaptic neuron. When the EPSP is greater than the threshold for excitation an action potential is generated.
A neuron will generate action potentials when it?
A neuron will generate action potential when it is stimulated by a neurotransmitter.
The start of an action potential?
An action potential starts when sodium channels in a neuron end open and sodium ions rush is, depolarizing the neuron's membrane.
What causes the vesicles inside a neuron to fuse with the plasma membrane?
An action potential in the neuron

What determines if an action potential is initiated in the postsynaptic neuron?
Every time neurotransmitter is released from the presynaptic neuron it generates an excitatory post synaptic potential(EPSP) in the postsynaptic neuron. When the EPSP is greater than the threshold for excitation an action potential is generated.
Where does an action potential start?
Action potentials are generated on a part of the neuron called the 'axon hillock' - the proximal most portion of the axon.
A neuron will generate action potentials when it?
A neuron will generate action potential when it is stimulated by a neurotransmitter.
What cell that generates action potential?
neuron
The start of an action potential?
An action potential starts when sodium channels in a neuron end open and sodium ions rush is, depolarizing the neuron's membrane.
What causes the vesicles inside a neuron to fuse with the plasma membrane?
An action potential in the neuron
Corresponds to the period of repolarization of the neuron?
Action Potential
Which part of the neuron can propagate an action potential?
axon
Action potential is generated by the movement of?
An action potential is propagated in a neuron through the activation of various voltage-gated and ligand-gated ion channels. Examples include sodium and calcium channels and nicotinic-acetylcholine receptors.
When an action potential reaches the end of a neuron it triggers the release of?
When an action potential reaches the end of a neuron, it triggers the release of neuotransmitters such as epinephrine (sympathetic) or achetylcholine (parasympathetic).
What is the rapid change in membrane's potential caused by the deplariztion of a neuron?
action potential
