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.


When impulses from various sources have an additive effect on a neuron the process is called?

When impulses from various sources have an additive effect on a neuron, the process is called summation. This can occur through temporal summation, where multiple impulses from the same source rapidly fire in succession, or spatial summation, where impulses from different sources converge at the same time to reach the neuron's threshold for firing.


What effect does the opening of the potassium channels have on the charge difference across the neuron's membrane?

Opening of potassium channels allows potassium ions to move out of the neuron, leading to hyperpolarization by increasing the negative charge inside the neuron. This action increases the charge difference across the membrane, known as the resting membrane potential, making the neuron less likely to fire an action potential.


Is the neuron ready to fire during the refractory period?

No, the neuron is not ready to fire during the refractory period. This period occurs immediately after the neuron has fired and is characterized by a temporary inability to generate another action potential.


What effect do neurotransmitters from one neuron have on the next neuron?

Neurotransmitters released from one neuron can either excite or inhibit the next neuron. Excitatory neurotransmitters make the receiving neuron more likely to fire an action potential, while inhibitory neurotransmitters make it less likely. This process allows for communication and coordination between neurons in the nervous system.

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 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"

What has to be crossed before the neuron fires?

The threshold potential must be reached for the neuron to fire. This is the level of depolarization that triggers an action potential to be generated and propagated along the neuron.


What is the voltage change at the receptor site of a neuron?

When a neuron is activated, there is a change in the voltage across the cell membrane at the receptor site. This change is known as a postsynaptic potential and can be either depolarizing (making the neuron more likely to fire an action potential) or hyperpolarizing (making the neuron less likely to fire an action potential).
