Nervous system/overview of neurons/Pump

POINT!

The Na-K pump moves potassium (K+) from outside to the inside, and sodium (Na+) from the inside to the outside of the cell.

The sodium (Na⁺)-potassium (K⁺) pump moves potassium (K⁺) from outside to inside the cell, and sodium (Na⁺) from inside to outside of the cell.　　As a result of this pump, the concentration of potassium (K⁺) is higher inside the cell, and the concentration of sodium (Na⁺) is higher outside the cell.
