hvilespændingen
Hvilespændingen, also known as the "resting membrane potential" in English, is a fundamental concept in physiology and neuroscience. It refers to the electrical potential difference across the plasma membrane of a cell when it is at rest, meaning it is not actively conducting an action potential or any other electrical activity. This potential is typically measured in millivolts (mV) and is crucial for the proper functioning of excitable cells, such as neurons and muscle cells.
The resting membrane potential is primarily determined by the distribution of ions across the cell membrane.
In most excitable cells, the resting membrane potential is negative, usually around -70 mV. This negative potential
The resting membrane potential is essential for the initiation and propagation of action potentials. When a
