Action potential is an event in which the potential of the membrane in a cell is first increased but then decreases. It is a characteristic feature to a variety of animal cells , including neurons, muscle cells and hormone-producing cells. Some plant cells also make them. Neurons play a very crucial part in cell-to cell communication. In pancreas beta cells, action potentials are linked with an insulin release. Plasma membranes contain a distinct type in voltage-gated, ion-channels that are used for creating action potential. The channels are closed in the event that membrane potentials are near its resting capacity of cells, however If the membrane's current potential rises then the channels become active. The channels that are active permit the inward flow of sodium ions, which increase the potential of membranes. The rapid inward flow sodium ions can alter the polarity of the membrane and consequently they become inactive. After this, potassium channels get activated and you can see an outward movement potassium ions . In the process, the membrane is returned back to its original position. A transient positive shift known as refractory interval prevents further travelling of the action potential. In animal cells , two types of these potentials are understood, one from voltage-gated potassium channels and the other which is caused by calcium channels that are voltage-gated.

Nearly all cells keep an electric field between their interior and exterior environment. The voltage of the cell is measured in milli volts (mV). The voltage of a typical animal cell is -70 mV. In the majority cells, few voltage fluctuations are believed to occur however in some cells, this is a common feature. Certain cells also exhibit the cycle of up and down as the voltage increases and declines. The duration of these potentials fluctuate over a large range. In brain cells, the up and down sequence of action potentials are completed in less than a thousandth of a second, whereas in other cells, cycles may take several seconds. The electrical ability of an animal cell is dependent upon the membrane structure. Cell membranes are composed of an lipid layer and proteins. The lipid layer serves as an insulation.

All animal cells are electrically polarized due to an electric charge that is known as membrane potential. In case of dendrites, neurons, axons and cell body have different electrical characteristics. The most exuberant part of one's neuron's axon hillock, but the axon and the cell body too can be stimulated. At the axon hillock the resting current is around 70 mV and the threshold potential is 55 mV. Synaptic messages to the brain cause depolarization, which causes the membrane potential to increase or fall. It is produced when enough depolarization develops until the membrane current reaches the threshold.

Action potential is the result from the voltage-gated channels within the plasma membranes of cells. A voltage-gated ion canal is actually a group made of proteins. They remain in plasma membranes and generates actions potential due to the fact that it could trigger a positive feedback loop. Membrane potential is accountable for control of the activity of Ion channels. The action potential is created by the positive feedback cycle that is carried out at full force. The frequency and duration are controlled by the bio-physical characteristics of the voltage-gated ion channels. There are a variety of ion channel types that are recognized that create positive feedback and result in the production of these potentials. The sodium channels that are voltage-gated participate in the production of high-speed potentials like those of nerve impulses. The slower ones, like those generated in muscles cells are controlled by calcium Ion channels.The ones that have been the most extensively studied voltage -gated Ion channels are the sodium ion channel that participate in quicker nerve impulse conduction.
