What the Effect of ouabain drug on a neuron ability to generate action potential?
what effect does the drug quabain have on neuron
What is dromotropic effect?
Dromotropic effect is the effect on conduction of current. It could be positive or negative depending on the final outcome. A negative dromotropic effect would mean decrease in conduction activity of current while positive would mean increase in conduction activity of current.
Who does the celiac disease affect the most?
It can effect anyone...
If you have a nonmodifiable risk factor for a disease what should you do?
alter the life styly factors that effect that disease in order to reduce your risk
What is inhibitory effect?
An inhibitory effect would curtail the intentions of the person planning an action.
What was the effect of curare on eliciting an action potential?
It creates an action potential
What effect does diameter of conduction fiber have on conduction of the heart?
The greater the diameter of the fiber that much greater the heartrate will be. Because at the synaptic junction wider surface area will release more neurotransmitter materials which in turn will provoke greater action potential and thus increased heartrate. ................................
What effect did an ether have on action potential?
Ether blocked the impulse transmission.
What are the factors which affect the nerve conduction velocity?
The factors affecting nerve conduction velocity are as follows:(i) Axon diameter:An axon with a larger diameter conducts faster. In an unmyelinated fiber, the speed of propagation is directly proportional to the square root of the fiber diameter (D), i.e.,Conduction velocity a D(ii) Myelination and saltatory conduction:Myelination speeds up conduction. Thus, the action potential travels electrotonically along the long myelinated segments, and fresh action potentials are generated only at the nodes. This is called saltatory conduction. In a myelinated neuron, the conduction velocity is directly proportional to the fiber diameter (D).(iii) Temperature:A decrease in temperature slows down conduction velocity, (iv) Resting membrane potential. Effect of RMP changes on conduction velocity is quite variable. Usually, any change in the RMP in either direction (hyper polarization or depolarization) slows down the conduction velocity.
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.
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 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 dromotropic effect?
Dromotropic effect is the effect on conduction of current. It could be positive or negative depending on the final outcome. A negative dromotropic effect would mean decrease in conduction activity of current while positive would mean increase in conduction activity of current.
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.
How does surface color affect rate of conduction?
The colour of a surface has no effect on the rate of conduction.
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.
