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.
What effect does hypocalcemia have on the cardiac action potential?
Hypocalcemia can lead to a prolongation of the cardiac action potential due to reduced calcium influx. This can result in an increased risk of arrhythmias, as well as potential impairment of cardiac muscle contractility.
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.
Will a hyperpolarization graded potential lead to an action potential?
No, hyperpolarization graded potentials do not lead to action potentials. Hyperpolarization makes the membrane potential more negative, which inhibits the generation of an action potential by increasing the distance from the threshold potential needed to trigger an action potential.
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 the addition of ether elicit an action potential?
Ether can transmit inhibitory effects.
What was the effect of curare on eliciting an action potential?
It creates 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.
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.
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 effect does hypocalcemia have on the cardiac action potential?
Hypocalcemia can lead to a prolongation of the cardiac action potential due to reduced calcium influx. This can result in an increased risk of arrhythmias, as well as potential impairment of cardiac muscle contractility.
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.
Where is old sea map in pokemon emerald?
You haft to get action replay to get it. get ether get gba action replay or duo action replay pack
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.
