• Membrane potential — Differences in concentration of ions on opposite sides of a cellular membrane lead to a voltage called the membrane potential. Many ions have a concentration gradient across the membrane, including potassium (K+), which is at a high inside and a… …   Wikipedia

• Action potential — In physiology, an action potential is a short lasting event in which the electrical membrane potential of a cell rapidly rises and falls, following a consistent trajectory. Action potentials occur in several types of animal cells, called… …   Wikipedia

• Reversal potential — This article is about the biological application of the Nernst equation. For the general equation, see Nernst equation. In a biological membrane, the reversal potential (also known as the Nernst potential) of an ion is the membrane potential at… …   Wikipedia
