In the resting neuron (that is, a neuron that does not have any neural impulses), the exterior of the cell membrane is positively charged and the interior is negatively charged relative to the outside. This difference in electrical charge across the plasma membrane is referred to as the resting membrane potential, and the membrane is said to be polarized. The sodium-potassium pump in the membrane maintains the difference in electrical charge established by diffusion of ions. This active transport mechanism moves 3 sodium ions (Na+) out of the cell while moving in 2 potassium ions (K+). Therefore, the major cation (positively charged ion) outside the cell in the extracellular fluid is Na+, and the major cation inside the cell is K+. The inner surface of the cell membrane is more negative than the outer surface, mainly due to intracellular proteins, which, at body pH, tend to be negatively charged.Read the overview information the PhysioEX Exercise 3 Neurophysiology of Nerve Impulses protocol as well as pages 179-188 in the text. Using the information in the the PhysioEX protocol and your textbook define the following p
