Vedclass · Answer

(A) During the resting state of a neuron,the axonal membrane is significantly more permeable to $K^+$ ions than to $Na^+$ ions.This is due to the presence of a large number of 'leak' channels for $K^+$ in the membrane,which allow $K^+$ to diffuse out of the cell down its concentration gradient.Conversely,the membrane is nearly impermeable to $Na^+$ ions and negatively charged proteins present in the axoplasm.This differential permeability,along with the action of the $Na^+-K^+$ pump,maintains the resting membrane potential.

During resting potential,the axonal membrane is more permeable to.........

How does the conduction of a nerve impulse occur?

During the conduction of a nerve impulse,the action potential results from the movement of

$A$: Presence of myelin sheath increases the rate of conduction of nerve impulse.
$R$: Ionic channels are absent in the area covered by myelin sheath; therefore,depolarization occurs only at the nodes of Ranvier,resulting in saltatory or jumping conduction.

Which of these processes occur during repolarisation of nerve fibre?
$(I)$. Open $Na^+$ channel
$(II)$. Closed $Na^+$ channel
$(III)$. Closed $K^+$ channel
$(IV)$. Open $K^+$ channel
