Resting Stage
Depolarizing Stage
Repolarizing Stage
Reset Phase
100

When a neuron is in a resting state there is more of this ion on the Extracellular Fluid (ECF).

What is Na+?

100

When a neuron is toward the end of the depolarizing stage, this is the approximate voltage of the neuron.

What is +30 mV?

100

This is the term used when a neuron is in the repolarizing stage and the voltage goes past -70mV. 

What is an Overshoot?

100

When a neuron is in the Reset Phase this ion is being pumped to the outside of the cell.

How many are being pumped across?

What is Na+?

What is 3?

200

When a neuron is in a resting state there is more of this ion on the Intracellular Fluid (ICF).

What is K+?

200

This is the voltage that must be reached in order for an action potential to be triggered.

What is -55 mV?

200

When a neuron is in a Repolarizing stage this is the ion that moves out of the cell.

What is K+?

200

When a neuron is in the Reset Phase this ion is being pumped to the inside of the cell.

How many are being pumped across?

What is K+?

What is 2?

300

When a neuron is in a resting state this is the approximate voltage of the ICF of the neuron.

What is -70 mV?

300

When a neuron is in a Depolarizing stage this is the ion that moves into the cell.

What is Na+?

300

During the Repolarizing Stage describe the net charge in the ECF vs. ICF.

What is the ECF is +/- (neutral) and the ICF is +/- (neutral)?

300

This is the charge of the ECF when the neuron is in the Reset Phase.

What is +?

400

During the resting state describe the net charge in the ECF vs. ICF.

What is the ECF is + and the ICF is -?

400

During the Depolarizing Stage describe the net charge in the ECF vs. ICF.

What is the ECF is - and the ICF is +?

400

What would happen if the neuron’s resting membrane potential was never reset? How would this impact the nervous system’s ability to function?

Inability to function.

The neuron would stay in a "stuck" state and would be unable to fire more action potentials to other neurons. (Paralysis and/or loss of sensory perception)

400

This is the charge of the ICF when the neuron is in the Reset Phase.

What is -?

500

This is the charge that the Reset Phase is attempting to return the neuron to.

What is -70 mV?
