Nernst equation is 62mV x log (conc ions outside/conc ions inside)
Ion movement through ion channels creates a membrane potential. K+ conc at
equilibrium is -90mV but because of the positive charge of Na+ inside, the ways
of Na+ is opposite K+ and creates a charge less negative inside the cell. The
resting potential reflects the small movement of sodium ions across a few open
sodium channels in the resting neuron.
