Action potential is an event in which the potential of the membrane of a cell first increases then decreases. It is a characteristic feature of a number of animal cells , namely muscles, neurons, and endocrine cells. Some plant cells also produce these. Neurons play a very crucial role in cell-tocell communications. In pancreas beta cells, actions potential is associated with that release of insulin. Plasma membranes are made up of a special kind of ion channels with voltage-gated voltages for creating action potential. These channels remain closed when the membrane potential is within what is the limit of the cell . However, when the membrane potential rises then the channels become active. If the channels are open, they permit an inward flow sodium ions. This can increase the cell's membrane potency. The rapid flow of sodium ions causes a change in the membrane's polarity and , consequently, they are inactive. In the following, potassium channels become active and that is followed by an outward flow of the potassium ions due to which the membrane returns to its normal state. A temporary negative shift, known as refractory time prevents the back motion of the potential. In animal cells typically two types of these potentials are described, for instance, one is generated due to voltage-gated sodium channels and the other which is generated by calcium channels that are voltage-gated.

Most cells have in a voltage differential between their environment and their inside. The cell's voltage is measured in millivolts (mV). The typical voltage of an animal cell is about -70 mV. In majority of cells very low voltage variations are thought to take place, but in certain cells, this is a standard characteristic. Some cells also show oscillations between up and down when they increase and decrease in voltage. The time between these potentials can be varied over a broad spectrum. In brain cells the up and down cycles of action potentials are completed in a fraction of a millisecond of a second while in other cells, the actions can last for a long time. The electrical power of a cell in the animal kingdom is dependent upon the membrane structure. Cell membranes consist of one layer of lipids along with proteins. The lipid layer serves as an insulation.

Animal cells are all electrically polarized as they maintain the same voltage, also called membrane potential. In case of dendrites, neurons, axons and the body of the cell have distinct electrical properties. The most exuberant part of neurons is the axon hillock. However, the axon and body too are excited. At the axon hillock the resting current is around 70 mV and the threshold potential is 55 mV. Synaptic stimulation to the neuron cause depolarization, causing the membrane potential to rise or fall. An action potential is created once enough depolarization has occurred and the membrane current reaches an upper limit.

Action potential is the outcome of the activity of voltage-gated ion channels in the plasma membranes of cells. The voltage-gated ion channel actually a group composed of proteins that remain in plasma membrane and produces action potential because it can result in the positive feedback loop. Membrane potential is accountable for maintaining the state of the these channels. Action potential is generated by the positive feedback cycle that runs at full speed. The duration as well as the magnitude are determined by the biophysical properties of the voltage-gated ionchannels. Many types of ion channels have been discovered that cause positive feedback processes that create these potentials. Voltage-gated sodium channels play a role in the creation of more powerful potentials that mimic those of nerve impulses. Slower ones like those produced in the muscle cells are mediated by calcium ion channels.The most thoroughly studied voltage-gated Ion channels are sodium ion networks that play an important role in the speedier nerve impulse conduction.
