Depolarization & Repolarization

What is depolarization?

• when the membrane potential becomes more negative at a particular spot on the neuron's membrane.

• when a change occurs inside a cell that causes the cell to have an increase in it’s positive electrical charge.

• restoration of the difference in charge between the inside and outside of a cell.

• when a neuron sends information down an axon, away from the cell body.

What is repolarization?

• when the membrane potential becomes more negative at a particular spot on the neuron's membrane.

• when a change occurs inside a cell that causes the cell to have an increase in it’s positive electrical charge.

• restoration of the difference in charge between the inside and outside of a cell following depolarization.

• when a neuron sends information down an axon, away from the cell body.

• first & third

• second & third

• second & first

• first & second
