oppdepolarisering
Oppdepolarisering is a concept that describes the process of reducing or eliminating the concentration gradient of ions across a cell membrane, particularly in the context of nerve cells and muscle cells. This phenomenon is fundamental to the generation and propagation of electrical signals in these excitable tissues.
The resting state of a typical cell membrane is characterized by a difference in electrical potential between
Oppdepolarisering occurs when positive ions move into the cell or negative ions move out of the cell,
This change in membrane potential is transient. Following oppdepolarisering, a process of repolarization typically occurs, where
