Q. is a brief, rapid, large change in membrane potential which is transmitted accross the membrane as a nerve impulse.

1. Action potential
2. Resting potential
3. Repolarization
4. Depolarization

Q. In the resting state of the neural membrane, diffusion due to concentration gradients, if allowed, would drive

1. $K^{+}$ and $N{a}^{+}$ out of the cell
2. $N{a}^{+}$ into the cell
3. $N{a}^{+}$ out of the cell
4. $K^{+}$ into the cell

Q. The factors that are responsible for the maintenance of the resting membrane potential of a neuron is/are

1. High resting state permeability for $K^{+}$ ions
