Zellpotenziale
Zellpotenziale refers to the electrical potential difference across the plasma membrane of a cell. This potential difference arises from the uneven distribution of ions, primarily sodium (Na+), potassium (K+), chloride (Cl-), and calcium (Ca2+), across the cell membrane. The cell membrane is selectively permeable, allowing some ions to pass through more easily than others, often via ion channels.
At rest, most cells maintain a resting membrane potential, which is typically negative on the inside relative
Changes in Zellpotenziale are crucial for cellular function, particularly in excitable cells like neurons and muscle
