When a neuron is in resting state i.e., not conducting any impulse, the axonal membrane is:
equally permeable to both Na+ and K+ ions
impermeable to both Na+ and K+ ions
comparatively more permeable to K+ ions and nearly impermeable to Na+ ions
comparatively more permeable to Na+ ions and nearly impermeable to K+ ions
when a neuron is not conducting any impulse (resting state), the axonal membrane is comparatively more permeable to potassium ions (K+) and nearly impermeable to sodium ions (Na+). This differential permeability helps maintain the concentration gradient required for the resting potential .
