cellepotentiale
Cellepotentiale, also known as membrane potential, refers to the difference in electrical potential between the interior and exterior of a biological cell. This potential difference is established and maintained by the selective permeability of the cell membrane to ions and the action of ion pumps. Typically, the inside of a cell is negatively charged relative to the outside, creating a resting membrane potential. This resting potential is crucial for various cellular functions, including nerve impulse transmission, muscle contraction, and nutrient transport.
The resting membrane potential is primarily determined by the concentration gradients of ions such as sodium
