... The RMP of a nerve cell is measured to be -70 mV or millivolts (inside / outside). It is established by different concentrations of ions in/out, with high K+ in, high Na+, Cl-, Ca++, out; high negatively charged proteins (A-) in. The RMP is maintained by the Na+K+ATPase pump (active transport). ...
