Answer:
2, 1, 4, 3.
Explanation:
The cell membrane potential may be defined as difference in the electric gradient inside and outside of the cell. The ions are important to create the voltage difference.
The nerve impulse transmission occurs by its propagation. The cell is at the resting membrane potential. The opening of sodium ions causes the inward diffusion of the ions. This causes the membrane potential become more positive and the cell depolarize. Then potassium ions starts diffuse in the cell and sodium ions move out. This causes the repolarization of cell.
Thus, the correct sequence is 2, 1, 4, 3.
The correct sequence is "2, 1, 4, 3".
The sequence of events:
The difference in the electric gradient inside and outside the cell can be used to determine the potential of the cellular membrane. These ions play a vital role in producing the variable voltage.
Nerve transmission happens as a consequence of its propagation. The cell's membrane potential is at rest. Inward diffusion of ions is caused by the opening of sodium ions.
The cell membrane becomes more positive as a result, and the cell depolarizes. Now potassium ions begin to diffuse within the cell, while sodium ions flow outward. This causes the cell to repolarize.
The sequence is:
- Sodium channels open, allowing sodium ion channels to open.
- The barrier is depolarized.
- The potassium channels open, allowing potassium to diffuse outwards.
- The membrane has been repolarized.
Therefore, the correct sequence is "2, 1, 4, 3".
