It is an event in which the potential of the membrane of a cell increases and then decreases. It is a signature characteristic of several animal cells , namely muscle cells, neurons, and Endocrine cells. Plant cells can also produce them. Neurons play an extremely important role in cell-to-cell communication. In pancreas beta cells, action potential is connected with an insulin release. Plasma membranes have a specific type of voltage-gated ion channels for creating action potential. The channels remain closed when the membrane potential is near an equilibrium potential for cells, however If the membrane's current potential rises the channels then they open. The channels that are active allow for an inward flow sodium ions. This can increase the cell's membrane potency. The fast inward flow of sodium ions result in changing the polarity of the membrane which causes them to stop functioning. Following that, potassium channels are activated and it is a flow of the potassium ions . In the process, the membrane is returned in its normal state. A transient positive shift known as refractory periods prevents back traveling of the action voltage. In animal cells , typically two kinds of these potentials are in existence, one which is produced through voltage-gated sodium channels, and another that is produced due to voltage-gated calcium channels.

A majority of cells experience the same voltage between their internal and external environments. The voltage of the cell is measured in millivolts (mV). The typical voltage for an animal cell is -70 mV. In the majority of cells, little voltage fluctuations are known to occur however in some cells this is a usual feature. Certain cells also exhibit up and down cycles as the voltage rises and falls. The duration of these voltages can vary widely. In brain cells the up and down cycles of action potentials are performed in less than a thousandth of a second, whereas in other types of cells the cycles can take up to a few seconds. The electrical function of a cell in the animal kingdom is dependent on the membrane structure. Cell membrane is comprised of layers of lipids, and proteins. The lipid layer functions as an insulation.

Animal cells are all electrically polarized since they have an electrical voltage that is called membrane potential. For cells, neurons and axons, dendrites and the body of the cell have distinct electrical properties. The most stimulated part of an individual neuron is the hillock but axon and cell body can also be excited. At the axon , the remaining potential is -70mV and the threshold potential is at -55 mV. Synaptic connections to the nerve trigger depolarization which causes the membrane potential to rise or fall. Action potentials are generated when enough depolarization happens and the membrane potential crosses the threshold.

Action potential is the outcome from the voltage-gated channels which are located within the plasma membranes of cells. A voltage-gated , ion channel is actually a cluster of proteins that remain embedded in the plasma and produce movement potential because it is able to be the cause of positive feedback loop. Membrane potential plays a role in setting the parameters of ion channels. Action potential is generated when the feedback cycle proceeds with full intensity. The duration and intensity are determined by the bio-physical properties associated with the voltage-gated ion channel. Numerous types of ion-channels are recognized that create positive feedback and cause the creation of these potentials. These sodium channels are involved in the creation of fast potentials that are similar to nerve impulse. These are the ones that are slower, similar to those found in the muscle cells are controlled by the calcium ion channels.The most researched voltage-gated ion channels are the sodium channels, which play a role in quicker nerve impulse conduction.
