  • How many statements are correct for resting state of axon ? i. The axoplasm inside the axon contains high concentration of K^(+) and negatively charged proteins and low concentration of Na^(+) ii. In contract, the fluid outside the axon contains a low concentration of K^(+) , is high concentration of Na^(+) and thus form a concentration gradient. iii. The outer surface of the axonal membrane possesses a positive charge while its inner surface becomes negatively charged. iv. The electrical potential difference across the resting plasma membrane is called an the resting potential. v. Resting stage is depolarised state vi. Resting potential is positive potential
