What is the effect of lidocaine on eliciting an action potential?

Ether prevents the action potential, by opening potassium ion pores, which allows the escape of potassium from the neurons, which results in hyper-polarization of the neuron, thus preventing the action potential from occurring.

What effect did an ether have on action potential?
Ether blocked the impulse transmission.
What effect does hypocalcemia have on the cardiac action potential?
It can prolong the cardiac action potential. It can also have other effects, such as torsades de pointes,and it can mask digitalis toxicity.
What was the effect of ether on elicciting an action potential?
Ether causes potassium ion pores to open, allowing potassium ions to leave the neuron, hyper-polarizing the neuron so it is unable to fire an action potential.
What is the difference between action potentials and synaptic potentials?
A synaptic potential exists at the INPUT of a neuron (dendrite), and an action potential occurs at the OUTPUT of a neuron (axon). (from OldGuy)(from Ilantoren:) A synaptic potential is the result of many excitatory post synaptic potentials (epsp) each one caused by the synaptic vesicles released by the pre-synaptic terminus. If there are enough of these epsp then the responses will summate and depolarize the post-synaptic membrane at the axon hillock enough to fire an action potential.
What does this mean Adversity has the effect of eliciting talents which in prosperous circumstances would have lain dormant?
basically means that in hard times(adversity), you discover talents you never thought you had.
What was the effect of curare on eliciting an action potential?
It creates an action potential
How does the effect of lidocaine differ from the effect of TTX?
They both decrease action potential duration, but TTX is the only one that decreases the maximum rate of depolarization.
What would be the effect on action potential conduction at a region of axon where the disease had its effect?
Depends on disease
What effect did an ether have on action potential?
Ether blocked the impulse transmission.
What the Effect of ouabain drug on a neuron ability to generate action potential?

What effect does hypocalcemia have on the cardiac action potential?
It can prolong the cardiac action potential. It can also have other effects, such as torsades de pointes,and it can mask digitalis toxicity.
Does lidocaine contain cocaine?
No, they are two different substances. Lidocaine was given the -caine ending only due to the anesthetic effect it shares with cocaine. However, sometimes cocaine is adulterated with lidocaine to increase the perceived potency of the product (due to lidocaine's numbing effects).
What is the relationship between the action potential and the synapse?
A synapse and an action potential have a flip-flopping cause and effect relationship, in that an action potential in a presynaptic neuron initiates a release of neurotransmitters across a synapse, which can then subsequently potentially trigger an action potential in the axon of the postsynaptic neuron, which would then cause release of neurotransmitters across a following synapse.
What was the effect of ether on elicciting an action potential?
Ether causes potassium ion pores to open, allowing potassium ions to leave the neuron, hyper-polarizing the neuron so it is unable to fire an action potential.
Why does tetrodotoxin effect your muscles?
It blocks the sodium channels that are required to create action potential in the muscles to make them contract.
What effect does adrenaline have on gut smooth muscle?
It makes the muscle totally relax as it blocks the action potential in the nerves.
What is a potential effect?
A negative effect is any result of an action which is perceived to be detrimental. This means its a subjective opinion. What might be negative to you may be positive to someone else.
