Vedclass · Answer

(B) In a resting state,the axonal membrane is polarized,meaning the inside is negatively charged relative to the outside.When a stimulus is applied,the permeability of the membrane to $Na^+$ ions increases,causing an influx of $Na^+$.This leads to depolarization,where the inside of the membrane becomes positively charged.Following this,the membrane permeability to $K^+$ increases,and $K^+$ ions move out,leading to repolarization,where the membrane potential returns to its original negative state.

When a neuron is stimulated to generate a nerve impulse,the electrical potential on the inside of the nerve membrane changes:

What is the conduction of an action potential at the Nodes of Ranvier called?

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

$A$: 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.

The action potential of a neuron is generated by which of the following?

The state in which the axonal membrane is positively charged on the outside and negatively charged on the inside is known as:
