What effect did an ether have on action potential?
Ether can enhance the excitability of nerve cell membranes, leading to a decrease in the threshold for action potential generation. This can result in an increase in the frequency and amplitude of action potentials.
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 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.
Are neurotransmitters that depress the resting potential called excitatory?
No, neurotransmitters that depress the resting potential are called inhibitory neurotransmitters. Excitatory neurotransmitters have the opposite effect, causing depolarization and increasing the likelihood of an action potential.
What is the effect of hypokalemia on membrane potential?
Hypokalemia (low potassium levels) can lead to a more negative resting membrane potential in cells. This enhances the threshold for depolarization and can result in muscle weakness, cramping, and cardiac arrhythmias due to impaired cell signaling.
Is the side effect of lasix is hypocalaemia or hypocalcemia?
Hypocalcemia
What was the effect of curare on eliciting an action potential?
It creates an action potential
The most serious effect of severe hypocalcemia is likely to be what?
The MOST serious effect would be death.
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 effect did an ether have on action potential?
Ether can enhance the excitability of nerve cell membranes, leading to a decrease in the threshold for action potential generation. This can result in an increase in the frequency and amplitude of action potentials.
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 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 effect does adrenaline have on gut smooth muscle?
It makes the muscle totally relax as it blocks the action potential in the nerves.
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 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.
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.
