- mechanism that restores the resting membrane voltage and intracellular ionic concentrations
- reversal of the resting potential due to an influx of sodium ions
- period during which potassium ions are diffusing out of the neuron because of a change in membrane permeability

The size (radius) of an oxygen molecule is about 2.0 ×10−10m. make a rough estimate of the pressure at which the finite volume of the molecules should cause noticeable deviations from ideal-gas behavior at ordinary temperatures (t= 300k ). assume that deviatons would be noticeable when volume of the gas per molecule equals the volume of the molecule itself.
