Action potential is an occurrence that occurs when the membrane potential of a particular cell increases then decreases. This is a characteristic trait of a variety of animals, including muscles cells, nerve cells, and Endocrine cells. Some plant cells also produce these. Neurons play an essential role in cell-tocell communications. In the beta cells of the pancreas, the action potential is associated with it being released by insulin. Plasma membranes contain a distinct type in voltage-gated, ion-channels that are used for producing action potential. These channels are shut while the membrane's current potential near the resting potential of the cell . However, if the membrane potential increases then the channels will become active. When they are opened, they let inward flow sodium ions that boost cell membrane power. The rapid flow inward of sodium ions changes the membrane's polarity and consequently they cease to function. The potassium channels after that are activated , and that is followed by an outward flow sodium ions. Due to this, the membrane is returned to its resting condition. A transient negative shift known as refractory period blocks back moving of the action-potential. In animal cells , two kinds of these are well-known, such as one of which is created due to voltage-gated sodium channels, and one that is generated by calcium channels that are voltage-gated.

Nearly all cells maintain in a voltage differential between the outside and inside. The cell's voltage is measured in millivolts (mV). The typical voltage for an animal cell is -70 mV. The majority of cells show small voltage fluctuations are reported to occur however in some cells this is a typical feature. Cells can show oscillations between up and down when the voltage goes up and down. The time between these potentials fluctuate over a large range. In brain cells the down and up cycles of action potentials are completed in less than a thousandth of a second. However, in different types of cells, the cycles can take up to a few seconds. The electrical properties of an animal cell is dependent on its membrane structure. Cell membrane is comprised of one layer of lipids along with proteins. The lipid layer functions as an insulation.

All animal cells are electrically polarized and maintain the difference in voltage called membrane potential. In case of the neurons, dendrites and the cell body all have different electrical properties. The most active part of an neuron is its axon hillock however axons and the cell body too can be stimulated. The axon hillock's resting current is around 70 mV and the threshold voltage is 55 millivolts. The synaptic inputs to the neurons cause depolarization, causing the membrane potential to increase or fall. Action potential is produced when enough depolarization happens and the membrane potential is at a threshold value.

The action potential results by the action of voltage-gated channels present in the plasma membrane of a cell. A voltage-gated , ion channel is actually a group consisting of proteins that stay in the plasma and produce action potential as it may trigger the positive feedback loop. Membrane voltage is responsible for setting the parameters of Ion channels. The action potential is created when the feedback cycle runs at full speed. The duration as well as the magnitude are controlled by the bio-physical characteristics of the ion channels that are voltage-gated. Different types of ion channels exist that can generate positive feedback circuits that ultimately produce these potentials. Voltage-gated sodium channels are involved in the creation of more powerful impulses like nerve impulse. These are the ones that are slower, similar to those found in the muscles cells are controlled by the calcium ion channels.The most thoroughly studied voltage-gated Ion channels are sodium ion channels involved in quicker nerve impulse conduction.
