Action potential is a phenomenon that causes the membrane potential for a specific cell initially increases before decreasing. It is a signature characteristic of many animals, including neurons, muscle cells and endocrin cells. Some plant cells also produce these. Neurons play an important part in cell-to cell communication. Beta cells of the pancreas actions potential is associated with hormone release. Plasma membrane has a particular type of voltage-gated ion channel for creating action potential. These channels remain closed while the membrane's current potential close to the resting potential of the cell but when the membrane's voltage increases the channels then they open. When they are opened, they allow an inward flow sodium ions, which boosts the membrane potential. The swift inward flow of sodium ions changes the membrane's polarity and as a result they stop functioning. The potassium channels, after which, become active and the flow outward potassium ions . In the process, the membrane is returned to its normal state. A transient negative shift referred to as refractory interval prevents further traveling of the action voltage. In animal cells , two kinds of these are recognized, for instance, one that is generated via voltage-gated channels and the second that occurs due to voltage-gated calcium channels.

Nearly all cells show the same voltage between their internal and external environments. The cell's voltage is measured in milli volts (mV). The typical voltage for an animal cell is around -70 mV. For the vast majority of cells, minor voltage fluctuations are observed as occurring, however in certain cells, this is a standard characteristic. Certain cells also exhibit up and down cycles as the voltage increases and declines. The duration of these voltages are variable across a variety of. In brain cells the down and up cycles of action potentials are completed in a fraction of a millisecond of a second while in other types of cells , sequences can take as long as a couple of seconds. The electrical ability of a cell in the animal kingdom depends on the membrane structure. Cell membrane is comprised of layers of lipids, and proteins. The lipid layer serves as an insulator.

All animal cells are electrically polarized . They maintain the voltage differential called membrane potential. For dendrites, neurons, axons and cell body have different electrical characteristics. The most excitable part of an neuron is its axon hillock however axons and the cell body are also excited. At the axon hillock the threshold potential for resting is -70mV and the threshold is 55 mgV. Synaptic messages to the brain cause depolarization, causing the membrane potential to increase or decrease. Action potentials are produced when enough depolarization builds up until the membrane current reaches an upper limit.

The action potential results of activity of voltage-gated ion channels that are found in the plasma membrane of cells. A voltage-gated ion canal is in fact a collection consisting of proteins that stay in plasma membranes and generates motion potential because it can result in positive feedback loop. Membrane potential is responsible for managing the state of these channels. The action potential is created when the positive feedback cycle is carried out at full force. The time and the intensity are dependent on the bio-physical properties of the ion channels with voltage-gated voltage. Many kinds of ionchannels are known to produce positive feedback and result in the production of these potentials. Voltage-gated sodium channels are involved in the creation of fast potentials similar to nerve impulse. Slower ones , like those made in muscle cells are mediated by calcium ion channels.The most rigorously researched voltage-gated Ion channels are sodium ion channel that participate in faster nerve impulse communication.
