When a neuron is an resting state i.e not conducting any impulse the axonal membrane is:

  • Option 1)

    comparatively more permeable to Na^{+}  ions  and nearly impermeable to K^{+} ions

  • Option 2)

    equally permeable to both Na^{+} and K^{+} ions.

  • Option 3)

    impermeable to both Na ^{+} and K^{+} ions

  • Option 4)

    comparatively more permeable to K^{+} ions and nearly impermeable to Na^{+} ions
