The action potential is a process that occurs when the membrane potential of a cell increases then decreases. It is a characteristic property of a variety of animal cells namely, neurons, muscle cells and cell types that are endocrine. Plant cells can also produce these. Neurons play a vital role in cell-to-cell communication. In the beta pancreas cells action potential is connected with in the production of insulin. Plasma membranes contain a distinct type of voltage-gated ion channels for creating action potential. They remain closed whenever the membrane's potential remains close to that of cells, however should the membrane potential increase then the channels open. When the channels open they permit an inward flow sodium ions. This in turn increases cell membrane power. The rapid inward flow of sodium ions changes the membrane's polarity and , in the process, turn off. After this, potassium channels get activated , and they are able to flow outward of the potassium ions . The result is that the membrane is returned back to its original position. A transient negative shift referred to as refractory time prevents the back movement of the action potential. In animal cells , two kinds of these potentials are in existence, one which is produced by the voltage-gated calcium channels, and the second one that is generated by calcium channels that are voltage-gated.

In most cells, there is some degree of voltage variation between the outside and inside. The voltage of the cell is measured in millivolts (mV). The voltage of a typical animal cell is -70 mV. In the majority of cells little voltage fluctuations are known to happen, but in a few cells this can be a normal feature. Certain cells may also exhibit an up-and-down cycle as the voltage increases and declines. The duration of these voltages differ across a broad range. In brain cells the down and up cycle of action potential are completed in a fraction of a millisecond of a second. However, in other cells, these cycles could take several seconds. The electrical properties of a cell in the animal kingdom is dependent upon the membrane structure. Cell membranes consist of an outer layer of lipids as well as proteins. The lipid layer serves as an insulation.

Animal cells are all electrically polarized . They maintain an electrical voltage that is known as membrane potential. In case of neuronal cells, axons and the cell body possess different electrical properties. The most excitable part of neurons is the axon hillock, however the axon as well as the cell body too can be stimulated. At the axon hillock the resting potential is -70mV and the threshold is 55 mgV. The synaptic inputs to the neurons result in depolarization causing the membrane potential to increase or fall. Action potential is produced when enough depolarization accumulates and that membrane potential reaches the threshold.

The action potential results of the work of voltage-gated Ion channels present in the plasma membranes of cells. An ion channel that is voltage-gated is actually a cluster consisting of proteins that stay in the plasma membrane. It generates action potential as it may trigger the 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 occurs at full strength. The time and amplitude of the action are controlled by the bio-physical characteristics of the ion channels that are voltage-gated. Many kinds of ionchannels have been discovered that cause positive feedback cycles and ultimately create these potentials. The sodium channels that are voltage-gated participate in the production of high-speed potentials similar to nerve impulses. Lesser ones, such as those created in muscle cells are mediated by calcium Ion channels.The most rigorously researched voltage-gated ion channels are the sodium channels, which play a role in faster nerve impulse conduction.
