It is an event where the potential for the membrane that a cell has first increases then decreases. It is the characteristic property of several animal cells , namely muscles cells, nerve cells, and hormone-producing cells. Some plant cells also make these. Neurons play an extremely important role in cell-tocell communication. In beta cells of pancreas actions potential is associated with in the production of insulin. Plasma membranes feature a unique type in voltage-gated, ion-channels that are used for producing action potential. These channels remain closed as long as the potential of the membrane is close to its resting capacity of the cell . However when the membrane potential rises the channels then they open. If the channels are open, they permit the inward flow of sodium ions that increase the cell's membrane potency. The rapid flow inward of sodium ions can alter the membrane's polarity and , in the process, disappear. The potassium channels then become activated , and inward flows of the potassium ions . As a result, the membrane returns to its resting condition. A transient negative shift known as refractory periods prevents back travel of the action potential. In the cells of animals, generally two types of these potentials exist, in existence, one of which is through voltage-gated sodium channels, and the second one that occurs due to calcium channels that are voltage-gated.

Nearly all cells maintain the voltage of their internal and external environments. The voltage of the cell is measured in milli volts (mV). The voltage of a typical animal cell is -70 mV. For the vast majority of cells, tiny voltage fluctuations are observed as occurring, however in certain cells this can be a normal characteristic. Cells can show variations in the voltage, as the voltage increases and declines. The duration of these potentials vary over a wide range. In brain cells the up and down sequence of action potentials are completed in less that a thousandth of a second. However, in other types of cells the cycle may last for several seconds. The electrical function of a cell in the animal kingdom is dependent upon the membrane structure. Cell membrane is made up of an outer layer of lipids as well as proteins. The lipid layer functions as an insulator.

All animal cells are electrically polarized since they have a voltage variation called membrane potential. In case of neurons, axonsand dendrites and the body of the cell have distinct electrical properties. Most excitable portion of neuron is called the axon hillock however axons and the cell body too are excited. In the axon hillock, the resting potential is -70mV and the threshold voltage is -55 mgV. Synaptic inputs into the neuron lead to depolarization. This causes the membrane potential to increase or decrease. A potential for action is created when enough depolarization builds up until the membrane's potential exceeds the threshold.

Action potential is the outcome by the action of voltage-gated channels in the plasma membrane of cells. A voltage-gated ion channel is actually a group of proteins which remain in the plasma and produce an action potential since it could result in positive feedback loop. Membrane Potential is responsible for controlling the level of Ion channels. The action potential is created in the event that the positive feedback process continues at its fullest. The time and amplitude of the action are determined by the bio-physical properties of the voltage-gated Ion Channels. A variety of Ion Channels are known that produce positive feedback cycles that eventually lead to the generation of these potentials. They are involved in the generation of stronger potentials , similar to those that result from nerve impulse. Slower ones , like those made in the muscles are controlled by the calcium ion channels.The most extensively studied voltage-gated Ion channels are the sodium-ion channels that contribute to higher speed nerve impulse transmission.
