In its resting state, the membrane surrounding a neuron is
permeable to potassium ions but only slightly permeable to sodium
ions. Thus, positive K ions can flow through the membrane in an
attempt to equalize K concentration, but Na ions cannot as quickly.
This leads to an excess of Na ions outside of the cell. If the
space outside the cell is defined as zero electric potential, then
the electric potential of the interior of the cell is negative.
This...
