Action potential is an occurrence where the membrane potential of a living cell first increases then decreases. This is a characteristic trait for a range of animal cells including muscle cells, neuron cells, and the endocrine cells. Plant cells can also produce them. Neurons play a significant role in cell-tocell communications. in pancreas beta cell action potentials are associated with releases of insulin. Plasma membrane has a particular type of voltage-gated ion channels for producing action potential. They remain closed whenever the membrane's potential remains close to the potential at rest of the cell . However if the membrane potential increases then the channels will become active. If the channels are open, they permit an inward flow sodium ions. This can increase its membrane potential. The fast inward flow of sodium ions result in changing the polarity of the membrane and , consequently, they cease to function. The potassium channels after that are active and it is a flow potassium ions . In the process, the membrane returns back to its normal state. A transient negative shift referred to as refractory interval prevents further forward motion of an action potential. In animal cells generally , two types of these potentials are known for example, one that is caused by voltage-gated sodium channels, and the second one that results from voltage-gated calcium channels.

Nearly all cells keep in a voltage differential between their external and internal environments. The cell's voltage is measured in milli volts (mV). The typical voltage of an animal cell is around -70 mV. In the majority cells, minimal voltage fluctuations have been observed to occur but in some cells this may be a common characteristic. Certain cells can also exhibit up and down cycles as the voltage drops and increases. The time between these potentials can vary widely. In brain cells, the up and down sequence of action potentials are executed in less then a thousandth of a second. However, in other types of cells , cycles could take several seconds. The electrical power of an animal cell is dependent on the membrane structure. The cell membrane is composed of the lipid layer as well as proteins. The lipid layer acts as an insulation.

All animal cells are electrically polarized as they maintain the difference in voltage known as membrane potential. For neuronal cells, axons and the body of the cell have distinct electrical characteristics. The most exuberant part of an neuron is its axon hillock. However, axons and cells body also get excited. At the axon hillock the maximum resting power is -70 mV and the threshold voltage is 55 millivolts. The synaptic inputs to the neurons lead to depolarization. This causes the membrane potential to rise or decrease. It is produced when enough depolarization occurs and the membrane's potential exceeds a threshold value.

Action potential is the outcome of the activity of voltage-gated ion channels within the plasma membranes of cells. Ion channels that are voltage-gated are in fact a collection composed of proteins that remain in the plasma membrane. It generates an action potential since it could trigger a positive feedback loop. Membrane current is responsible control of the activity of Ion channels. The action potential is created in the event that the positive feedback process gets full power. Its duration and amplitude are determined by the bio-physical properties associated with the voltage-gated ion channel. Different types of ion channels are known that produce positive feedback circuits that ultimately create these potentials. The sodium channels with voltage are involved in the creation of more powerful potentials similar to nerve impulse. The slower ones, like those generated by muscle cells are mediated by the calcium Ion channels.The most studied voltage-gated Ion channels are the sodium channels, which play a role in quicker nerve impulse conduction.
