It is an event where the potential for the membrane for a specific cell initially increases before decreasing. It is a typical characteristic of many animal cells including muscles cells, neurons and hormone-producing cells. Some plant cells also produce them. Neurons play an essential role in cell-to-cell communication. In pancreas beta cells, action potentials are associated with production of insulin. Plasma membrane has special type of voltage-gated channels for producing action potential. The channels are closed in the event that membrane potentials are within its resting capacity of the cell . However, when the membrane potential rises the channels then they open. The channels that are active allow an inward flow of sodium ions that increase the membrane potential. The rapid inward flow sodium ions affects the polarity of the membrane and they are inactive. The potassium channels, after which, become activated , and you can see an outward movement of the potassium ions . The result is that the membrane is returned to its original state. The transient negative change known as refractory period prevents back travelling of the action potential. In animal cells typically two types of these potentials exist, understood, one that is caused via voltage-gated channels, and another that results from calcium channels that are voltage-gated.

Nearly all cells maintain some degree of voltage variation between their external and internal environments. The voltage of the cell is measured in millivolts (mV). The typical voltage for an animal cell is around -70 mV. The majority of cells show low voltage variations are thought to take place, but in certain cells this is an expected characteristic. Some cells also show an up-and-down cycle as the voltage decreases and increases. The time between these potentials vary over a wide range. In brain cells the down and up sequence of action potentials are completed in a fraction of a millisecond of a second, whereas in different types of cells, the cycle may last for several seconds. The electrical characteristic of an animal cell is dependent upon the membrane structure. The cell membrane is composed of a layer of lipids and proteins. The lipid layer serves as an insulator.

Animal cells are all electrically polarized as they maintain a voltage difference called membrane potential. For dendrites, neurons, axons and the cell body possess different electrical properties. The most exuberant part of an individual neuron is the hillock. However, axons and cells body also get excited. At the axon , the maximum resting power is -70 mV and the threshold voltage is -55 mV. The synaptic inputs to the neurons induce depolarization and cause the membrane potential to rise or decrease. Action potentials are generated when enough depolarization develops until the membrane voltage reaches the threshold.

The action potential results of activity of voltage-gated ion channels located in the plasma membranes of cells. A voltage-gated , ion channel is actually a cluster of proteins that are embedded in the plasma membrane. It generates motion potential because it can generate the positive feedback loop. Membrane potential is accountable for control of the activity of ion channels. The action potential is created whenever the positive feedback runs at full speed. The duration as well as the magnitude are determined by the biophysical properties of the voltage-gated ion channels. Numerous types of ion-channels are identified that generate positive feedback cycles that eventually cause the creation of these potentials. The sodium channels that are voltage-gated participate in the generation of stronger possibles that resemble those produced by nerve impulses. These are the ones that are slower, similar to those found by muscles cells are controlled by the calcium ion channels.The the most intensely studied voltage-gated ion channels are the sodium-ion channels that contribute to higher speed nerve impulse transmission.
