Then the signal will not be sent. The entire chain leading from the CNS to wherever it's going will be disturbed and will come to a halt.

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.
A neuron starts to fire an impulse by the influx of what ions?
sodium
Is the neuron ready to fire during the refractory period?
Refractory period
When impulses from various sources have an additive effect on a neuron the process is called?
convergence
What effect does the opening of the potassium channels have on the charge difference across the neuron's membrane?
repolarization
What effect do neurotransmitter from one neuron have on the next neuron?
The neurotransmitters from one neuron have direct effect on the next neuron. They are channels that are used to transmit messages in the nerves.
What the Effect of ouabain drug on a neuron ability to generate action potential?
what effect does the drug quabain have on neuron

What effects do neurotransmitters from the neuron have on the next neuron?
The neurotransmitters from one neuron have direct effect on the next neuron. They are channels that are used to transmit messages in the nerves.
What triggers at a point in which a neuron will fire?
Threshold
What cause neuron to fire?
The neuron adds up all the excitatory and inhibitory inputs and fires when they reach its threshold of excitation.
Can a neuron fire half of its neurotransmitters?
no it's an "all or nothing"
A neuron starts to fire an impulse by the influx of what ions?
sodium
Is the neuron ready to fire during the refractory period?
Refractory period
What determines the effect that a neurotransmitter has on the postsynaptic neuron?
the receptors on the postsynaptic membrane
What is mean by the all or none response of a neuron?
The simplest sense, the all-or-none principle of neuronal firing means that a neuron will either fire or it won't, there is no "half" firing. When a neuron receives excitatory input.
When impulses from various sources have an additive effect on a neuron the process is called?
convergence
