Depolarisoitumiseen
Depolarisation is a fundamental process in biology and biochemistry, particularly in the context of nerve cells and muscle cells. It refers to the reversal of the resting membrane potential, which is the difference in electrical charge across the cell membrane. This resting potential is maintained by the selective permeability of the cell membrane to ions, primarily sodium (Na+) and potassium (K+).
When a nerve or muscle cell is at rest, the inside of the cell is negatively charged
Depolarisation occurs when the cell membrane becomes more permeable to sodium ions, allowing them to rush into
Depolarisation is a critical step in the generation and transmission of nerve impulses. It is followed by
