Plasma membrane
The unite of measurement of potential difference is the volt (V),and the transmembrane potential of a neuron is usually near 0.07V.Such a value is usually expressed as -70 mV (or-70 millivolts-thousandths of a volt)with the minus sign indicating that the interior is negatively charged.
The cytosol contains an abundance of negatively charged proteins, whereas the extracellular fluid contains relatively few. These proteins cannot cross the plasma membrane.
-70 -30 -0 -30
The sodium-potassium exchange pump ejects 3 Na+ for every 2 k+ recovered from the extracellular fluid. At a transmembrane potential of-70 mV, the rate of Na+ entry versus K+ loss is 3:2, and exchange pump maintains a stable resting potential.
Potassium ions can diffuse out of the cell through potassium leak channels.
Sodium ions can diffuse into the cell through sodium leak channels.
