Why does every cell, not just neurons, have a resting membrane potential?

Remember there are dissolved molecules that form ions both inside and outside the cell. These ions have charge.
Also, remember these cells also need to move things back and forth across the cell membrane and need set up gradients.

Na+/K+ ATPase maintains a membrane potential in all different types of cells, not just neurons
if there were no potential set up, then the cells would prob not work as they work now. there are things the cell must do in order to become stimulated and one of these things is keeping a negative potential so, as in neurons, they can depolarize to a signal and do whatever is necessary (send another messenger, release something else within the cell etc).
