It is an event in which the potential of the membrane in a cell is first increased but then decreases. It is an characteristic characteristic of several cell types in animals, such as muscles, neurons and cell types that are endocrine. Plant cells also produce them. Neurons play an extremely important role in cell-to-cell communication. In the beta pancreas cells action potentials are linked with that release of insulin. Plasma membranes comprise a particular kind of ion channels with voltage-gated voltages for creating action potential. These channels remain closed whenever the membrane's potential remains close to those of the cell . However, when the membrane potential rises then the channels are activated. As the channels become open, they permit an inward flow sodium ions which increases the membrane potential. The rapid flow inward of sodium ions alters the polarity of the membrane and they turn off. After that potassium channels become activated , and it is a flow potassium ions . The result is that the membrane returns in its normal state. A transient negative shift known as the refractory phase prevents the return travelling of the action potential. In animal cells , two kinds of these voltages are in existence, one which is triggered by the voltage-gated calcium channels, and the second one that occurs due to calcium channels that are voltage-gated.

Most cells have an electrical voltage gap between their exterior and interior environments. The cell's voltage is measured in millivolts (mV). The typical voltage of an animal cell is about -70 mV. In majority of cells very small voltage fluctuations are reported to occur but in some cells this is an expected feature. Certain cells also exhibit oscillations between up and down when the voltage decreases and increases. The duration of these potentials can vary widely. In brain cells the down and up cycle of action potential are completed in less than thousandth of a second. In other cells, these cycle may last for several seconds. The electrical characteristic of a cell in the animal kingdom depends on the membrane structure. Cell membranes are composed of an outer layer of lipids as well as proteins. The lipid layer serves as an insulator.

All animal cells are electrically polarized and maintain an electric voltage which is known as membrane potential. In case of neurons, , dendrites and cells have distinct electrical properties. The most excitable component of neurons is the axon hillock. However, the axon and body can also be stimulated. The axon hillock's resting potential is -70 mV and the threshold voltage is 55 MV. Synaptic stimulation to the neuron cause depolarization, causing the membrane potential to rise or fall. It is produced when enough depolarization happens and the membrane voltage reaches an upper limit.

Action potential is the outcome that voltage-gated ion channels found within the plasma membrane of a cell. A voltage-gated ion channel is actually a cluster of proteins , which are encased in plasma membranes and generates motion potential because it can be the cause of the positive feedback loop. Membrane Potential is responsible for control of the activity of ion channels. Action potential is generated in the event that the positive feedback process continues at its fullest. Its duration and amplitude are controlled by the bio-physical characteristics of the voltage-gated ionchannels. Numerous types of ion-channels are recognized that create positive feedback processes that produce these potentials. The sodium channels with voltage are involved in the generation of larger potentials that mimic those of nerve impulses. Slower ones , like those made by muscle cells are controlled by the calcium ion channels.The most rigorously researched voltage-gated Ion channels are sodium ion channels which are involved in higher speed nerve impulse transmission.
