When an axon is not conducting an impulse is known as?
Resting Potential
What is the correct order that information passes through in a neuron?
The flow of information across nerve cells is called a nerve impulse in which the axons of the cell must depolarize, repolarize and go through a refractory period before reaching the resting potential. At this point, another impulse can occur.
What is The time an action potential begins until the resting potential has stabilized is?
1/2500 sec is the absolute refractory period.
What do you call the state of a neuron when it is not firing a neural impulse?
Resting potential.
Do all cells have a resting potential of -70mV?
No there is a range of resting potentials. For example retinal ganglion cells have a resting potential of -65 mV while the endocochlear potential is +80 mV.

What name is given to a neuron that is not sending a nervous impulse?
resting potential
How is a resting potential achieved in the nervous system?
The resting nerve cell is not being stimulated to send a nerve impulse
What is resting potential?
A rest potential is the potential difference between two sides of the membrane of nerve cells when the cell is not conducting an impulse. =)
What happens to the size of an action potential as it continues down the axon?
I belive the size of the axon potential remains constant at a depolarisation of +40 mv and a resting potential of -70mv for most nerves. The frenquency of action potentials is the factor that determines the strength of the nerve impulse.
Describe the path a nerve impulse travels through?
When an impulse travels to the brain, it is first received by sensory receptors, then sent through the neurons by an electrical current. When the neuron receives the signal from a sensory receptor or from another neuron, the nucleus processes the impulse and then sends it down the axon. When a neuron is resting, the inside of the cell has a negative charge caused by active transport of NA and K molecules. This is called the resting potential. When the impulse hits the axon, the electricity causes NA pumps to open, allowing a flow of positively charged the molecule into the cell, causing the charges to switch. This is called the action potential. As the impulse passes, the K pumps open, restoring the original charge. When the impulse reached the end of the axon, neurotransmitters chemically pass the impulse to the next neuron. ;
