Membrane potential
Membrane potential refers to the difference in electric charge across a cell's membrane, created by the uneven distribution of ions (like sodium and potassium) inside and outside the cell. This potential is crucial for various cellular processes, including the communication between nerve cells and muscle contractions. When a cell becomes activated, this potential changes rapidly, allowing signals to travel along nerves or triggering muscle movement. Essentially, membrane potential is like the electrical battery of a cell, enabling it to perform its functions and respond to stimuli effectively.

Membrane potential refers to the electrical charge difference across a cell's membrane. Cells maintain a balance of charged particles (ions) inside and outside, creating a voltage. This potential is essential for various functions, such as signaling in nerve cells and muscle contractions. When a stimulus occurs, the membrane potential can change, allowing cells to communicate and respond to their environment. Essentially, it's like a battery that powers cellular activities, enabling functions critical for life.
