Explain the difference between a polarized neuron and a depolarized neuron
What will be an ideal response?
A neuron is polarized when there are more positively charged ions located on the outer surface of the membrane and less positively charged ions situated on the inner surface of the membrane. A neuron is at rest when it is polarized. Depolarization occurs when the sodium ions, normally located outside the neuron's membrane, rush into the cell. Now, the interior surface of the membrane carries a positive charge due to the presence of more positively charged ions while the exterior surface of the membrane carries a negative charge due to the smaller number of positively charged ions.
