They are stored in the cortical and pith cells, also known as the parenchyma cells.

Answer:
Statements A,C, D and E are correct while statement B is wrong
Explanation:
A. During depolarization phase, the gated sodium ion channels on the neuron's membrane opens for the flow of sodium ions (Na+) into the cell.
C. Once the threshold of depolarization reaches, action potential will occur.
D. Hyperpolarization inhibits action potentials by increasing the stimulus required to move the membrane potential to the action potential threshold.
E. Finally, the cell is brought back to its resting membrane potential by the reflux of extra K+ ions out of the cell via the potassium leakage channels.
B is wrong because at rest, excited cells are negatively charged
White blood cells assist the immune system and are used to fight off infections. If that's not the correct answer, it would be T-cells. However T-cells are a subtype within the white blood cells, so if the question is asking you in general, it would be white blood cells. If it's asking for a specific type, then it would be T-cells.
