Physiology General physiology 9b3a338c True regarding RMP is all except A -70 mV in neurons B Is due to K+ ions C Na+ - K+pump 3 Na+out of cell & 2K+ inside D Na+ - K+ pump 3K+ out of cell & 2 Na+ inside of cell High-Yield Explanation RMP of nerve Fibre is - 70mV. Na+K+ATPase pump out 3Na+ in exchange for only 2K+. (REF: DISEASES GANONG'S REVIEW OF MEDICAL PHYSIOLOGY)
