A) The resting axonal membrane is comparatively more permeable to potassium ions and nearly impermeable to sodium ions
B) In the resting membrane the outer surface of the axonal membrane possesses a positive charge while its inner surface is negatively charged and, therefore, is polarized
C) The membrane becomes depolarised due to rapid influx of \[N{{a}^{+}}\] on applying thresh old stimulus
D) Depolarisation is followed by repolarisation in which rapid efflux of \[N{{a}^{+}}\] takes place restoring the resting potential of the membrane at the site of excitation
