A neuron will generate action potentials when it?
A neuron will generate action potential when it is stimulated by a neurotransmitter.
A series of similar stimuli that increases change in local membrane potential is called?
Action potential
Neuron receives a series of stimuli whose effect is excitatory but subthreshold?
If a neuron receives a series of stimuli that have an excitatory effect but do not reach the threshold for action potential initiation, the neuron will not fire. This is because the individual stimuli do not generate a strong enough depolarization to reach the threshold. However, if enough subthreshold stimuli are received in a short period of time, they can summate and reach the threshold, generating an action potential.
Where do neurotransmitters that bind the postsynaptic membrane generate?
action potential
Does strong stimuli cause the strength of action potentials to increase?
No, it doesn't become "larger" - the peak potential is always the same - it is a digital signal. Stronger stimulus will cause the nerve cell to fire more often - therefore stimulus strength is translated as action potential frequency.
What kinds of stimuli can elicit action potential?
Electrical , heat and chemical stimuli
A neuron will generate action potentials when it?
A neuron will generate action potential when it is stimulated by a neurotransmitter.
Why does curare appear to generate an action potential?
It doesn't. I prevents an action potential from forming.

For a brief time after an action potential begins a muscle fiber or neuron cannot generate another action potential This time is called the?
five second silence
What are autorhythmic fibers?
They are fibres which generate AP(action potential) which trigger heart contractions.
What are the events that must occur to generate action potential?
Local polarization is the first step. Next the generation and propagation of an action potential. Lastly repolarization has to take place.
When action potential generate the internal part of the axon becomes______ due to influx of sodium?
Positive
Inhibitory postsynaptic potential is associated with what?
An inhibitory postsynaptic potential (IPSP) is a kind of synaptic potential that makes a postsynaptic neuron less likely to generate an action potential.
