When a neuron is not conducting any impulse,$i.e$.,resting,the axonal membrane is comparatively more permeable to:

The rate of rise of action potential and its amplitude are determined by the concentration of

During the transmission of a nerve impulse through a nerve fibre,the potential on the inner side of the plasma membrane has which type of electric change?

Select the correct sequence of statements regarding the conduction of a nerve impulse and select the correct option given below.
$i.$ Rapid influx of $Na^{+}$ inside the axon.
$ii.$ $Na^{+}$ gates are closed and $K^{+}$ gates open after the refractory period.
$iii.$ Intracellular fluid is electronegative and the potential difference is $-70 \ mV$.
$iv.$ Extracellular fluid becomes electronegative.
$v.$ Disturbance to the resting potential.

The ionic gradients across the resting membrane are maintained by the

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