Which of the following statement is wrong regarding conduction of nerve impulse? (a) In a resting neuron, the axonal membrane is more permeable to K+ ions and nearly impermeable to Na+ ions. (b) Fluid outside the axon has a high concentration of Na ions and low concentration of K+ , in a resting neuron. (c) Ionic gradients are maintained by Na-K pumps across the resting membrane, which transport 3Na+ ions outwards for 2K+ into the cell.(d) A neuron is polarized only when the outer surface of the axonal membrane possess a negative charge and its inner surface is positively charged.
