Vedclass · Answer

(D) $1$. At the resting state,the axonal membrane is polarized,meaning the inner side is negatively charged relative to the outer side.$2$. When a stimulus is applied,the membrane becomes permeable to $Na^+$ ions,causing an influx of $Na^+$. This leads to depolarization,where the inner side becomes positively charged.$3$. Following this,the membrane becomes permeable to $K^+$ ions,which move out,leading to repolarization,where the inner side becomes negatively charged again.$4$. Thus,the sequence of charge on the inner side is negative (resting),positive (depolarized),and negative (repolarized).

During the conduction of a nerve impulse along a neuron,what is the nature of the electrical charge on the inner side of the plasma membrane?

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

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

$A$ : The imbalance in the concentration of $Na^+, K^+$ and proteins generates the resting potential.
$R$ : To maintain the unequal distribution of $Na^+$ and $K^+$,the neurons use electrical energy.

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.

When a stimulus is applied to the membrane of a neuron,it causes a rapid influx of
