Action potential refers to an event during which the membrane power of a living cell first increases before decreasing. It is a typical characteristic of a number of animal cells including muscle cells, neurons, and the endocrine cells. Plant cells also produce these. Neurons play a crucial role in cell-to-cell communication. In beta cells of pancreas action potentials are linked with an insulin release. Plasma membranes contain a distinct type of voltage-gated channels for creating action potential. The channels are closed at times when membrane potential is within an equilibrium potential for the cell but when the membrane's voltage increases then the channels become active. As the channels become open, they allow an inward flow sodium ions. This increases the cell's membrane potency. The rapid flow of sodium ions can alter the membrane's polarity and , as a consequence, they stop functioning. Following that, potassium channels are activated , and then there's an outward flowing of the potassium ions due to which the membrane is returned back to its normal state. A transient , negative shift known as refractory duration prevents the reverse travelling of the action potential. In animal cells , two types of potentials are identified, for instance, one of which is due to voltage-gated sodium channels, and the second one that can be produced by voltage-gated calcium channels.

A majority of cells experience an electric field between their interior and exterior environment. The cell's voltage is measured in millivolts (mV). The typical voltage for an animal cell is -70 mV. In majority of cells very tiny voltage fluctuations are observed to occur but in some cells this is an expected feature. Some cells show the cycle of up and down as the voltage goes up and down. The duration of these voltages can be varied over a broad spectrum. In brain cells, the up and down phase of an action potential are completed in a fraction of a millisecond of a second while in different types of cells, the actions can last for a long time. The electrical property of an animal cell is dependent on the membrane structure. Cell membrane is made up of a layer of lipids and proteins. The lipid layer serves as an insulator.

All animal cells are electrically polarized . They maintain an electric charge that is called membrane potential. In case of neurons, axons, dendrites and the body of the cell have distinct electrical characteristics. The most exuberant part of an individual neuron is the hillock, but the axon and the cell body too can be stimulated. The axon hillock's maximum resting power is -70 mV and the threshold potential is -55 MV. Synaptic signals to the neuron cause depolarization, causing the membrane potential to rise or fall. Action potential is created when enough depolarization occurs and the membrane potential crosses a threshold value.

Action potential is the outcome from the voltage-gated channels located in the plasma membrane of a cell. The voltage-gated channel is actually a cluster consisting of proteins that stay inside the plasma membrane. These proteins produce an action potential in order to create positive feedback loop. Membrane Potential is responsible for managing the state of these channels. Action potential is generated when the feedback cycle takes place at full intensity. The duration as well as the magnitude are determined by the bio-physical properties of the ion channels that are voltage-gated. There are a variety of ion channel types that are known that produce positive feedback cycles , which eventually produce these potentials. The sodium channels that are voltage-gated participate in the production of high-speed potentials , similar to those that result from nerve impulse. They are slower than those that occur in the muscle cells are mediated by calcium Ion channels.The most thoroughly studied voltage-gated ion channels are the sodium-ion channels that contribute to greater speed of nerve impulse conduction.
