Vedclass · Answer

(C) When a stimulus is applied to a nerve fiber,the permeability of the axonal membrane to $Na^+$ ions increases significantly.This leads to a rapid influx of $Na^+$ ions into the intracellular space,causing depolarization of the membrane.This change in membrane potential results in the generation of an action potential or nerve impulse.Therefore,the membrane becomes more permeable to $Na^+$ ions during the initiation of a nerve impulse.

$A$ nerve impulse is generated in a nerve fiber when the membrane becomes more permeable to:

What is resting potential?

In the resting stage of a neuron,the concentration gradient is generated due to:

Give scientific reasons:
$(1)$ In an excited nerve fibre region,a positive charge is created inside the plasma membrane.
$(2)$ In some animals,the conduction of nerve impulses is saltatory.

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

The potential difference in the membrane,which is responsible for the conduction of an impulse,is brought about by a change in the membrane:
