What is the difference between a red blood cell and a nerve cell?

the nerve cell is the white cell and it is white but it doesnt care as much blood as the red blood cell does that's the difference. Also, the nerve cell is the white cell and it is white but the red blood carries blood. Wait, I think the nerve cell is the white cell is white. White Cell=Nerve Cell*white.

Cell=Nerve/White
