What is the response if you increase the stimulus intensity past the threshold level for a neuron?
Try increases dramatically......
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.
The action potential is generated when a stimulus?
When a stimulus stimulates a neuron above the threshold, the action potential is generated.
What causes the vesicles inside a neuron to fuse with the plasma membrane?
An action potential in the neuron

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 action potential is generated when a stimulus?
When a stimulus stimulates a neuron above the threshold, the action potential is generated.
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
Where in a neuron can an action potential be generated?
axon hillock
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 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.
What is the rapid change in membrane's potential caused by the deplariztion of a neuron?
action potential
