depolarizációval
Depolarizációval, also known as depolarization, is a process in which the electrical potential difference across a cell membrane is reduced. This occurs when the concentration of positively charged ions (such as sodium) inside the cell increases, while the concentration of negatively charged ions (such as potassium) decreases. Depolarization is a crucial step in the generation and transmission of nerve impulses.
The process begins when a stimulus, such as a chemical or electrical signal, causes ion channels in
Depolarization is followed by repolarization, where the cell membrane becomes more negative again due to the
Depolarization can also occur in non-neuronal cells, such as muscle cells, where it plays a role in
Depolarization is a fundamental process in physiology and is essential for various biological functions, including communication
