The action potential is a process where the membrane potential that a cell has first increases before decreasing. It is a common characteristic of several animal cells , namely muscles, neurons, and cell types that are endocrine. Plant cells can also produce them. Neurons play an important function in cell-to-cell communication. in pancreas beta cell action potentials are connected to an insulin release. Plasma membranes are made up of a special kind of voltage-gated channels for producing action potential. The channels remain closed while the membrane's current potential within it's resting value of the cell but when the membrane's potential increases then the channels open. Once the channels are open, they let inward flow sodium ions. This can increase your membrane's potential. The rapid flow of sodium ions leads to a change in the polarity of the membrane and as a result they are inactive. In the following, potassium channels become active and they are able to flow outward of the potassium ions . As a result, the membrane is returned back to its normal state. The transient negative change known as refractory time prevents the back travel of the action potential. In animal cells , typically two types of potentials are understood, one which is produced because of voltage-gated sodium channels and another one that is generated by voltage-gated calcium channels.

The majority of cells have the same voltage between their interior and exterior environment. The voltage of the cell is measured in millivolts (mV). The voltage of a typical animal cell is around -70 mV. In most cells, minimal voltage fluctuations have been observed to take place, but in certain cells, this is a common characteristic. Certain cells can also exhibit the cycle of up and down as the voltage drops and increases. The duration of these voltages vary over a wide range. In brain cells the down and up cycles of action potentials are executed in less then a thousandth of a second. However, in other types of cells the sequences can take as long as a couple of seconds. The electrical properties of an animal cell is dependent on the membrane structure. Cell membrane is made up of the lipid layer as well as proteins. The lipid layer serves as an insulator.

All animal cells are electrically polarized , as they sustain a voltage variation called membrane potential. In case of neurons, axonsand dendrites and cell bodies have different electrical characteristics. The most stimulated part of an neuron is its axon hillock, however the axon as well as the cell body can also be stimulated. In the axon hillock, the resting potential is -70mV and the threshold potential is -55 mV. Synaptic messages to the brain result in depolarization causing the membrane potential to increase or decrease. Action potential is produced when enough depolarization accumulates and the membrane voltage reaches an upper limit.

The action potential results in the function of voltage-gated channels found within the plasma membranes of cells. A voltage-gated Ion Channel is in fact a collection of proteins that are embedded inside the plasma membrane. These proteins produce an action potential since it could be the cause of an positive feedback loop. Membrane potential is responsible for controlling the level of these channels. The action potential is created by the positive feedback cycle that occurs at full strength. The time and the intensity are dependent on the bio-physical properties of the voltage-gated ion channels. A variety of Ion Channels are available that are believed to generate positive feedback and create these potentials. These sodium channels are involved with the creation of higher impulses like nerve impulse. More slow ones such as those produced in muscle cells are mediated by calcium Ion channels.The most extensively studied voltage-gated channel are sodium ion channel that participate in more rapid nerve impulse conduction.
