The mineral necessary for nervous conduction is

In the resting stage of a neuron,the concentration gradient allows the diffusion of which ions?

Which of the following statement/s is/are correct with respect to generation and conduction of nerve impulse?
i. The resting potential difference is $-70 \text{ mV}$.
ii. The voltage-gated $Na^{+}$ and $K^{+}$ channels operate together and are self-closing.
iii. At the peak of action potential,the potential difference rises to $+30$ to $+60 \text{ mV}$.
iv. In medullated nerve fibre,the action potential is conducted as a wave of membrane depolarization.
v. The resting potential is maintained by the closure of gated channels of $Na^{+}$ and $K^{+}$.

During the resting state,the axonal membrane allows the movement of which ions due to the concentration gradient?

The potential difference between the outside and inside of a nerve fiber before excitation is known as:

The potential difference across the membrane of a relaxed muscle fibre is called resting potential. It amounts to about
