Action potential is an occurrence that causes the membrane potential of a particular cell increases before decreasing. It is a characteristic feature that is present in a wide variety of animals, including muscles cells, neurons and the endocrine cell. Certain plant cells also produce them. Neurons play a crucial role in cell-tocell communication. In pancreas beta cells, action potentials are connected to the release of insulin. Plasma membranes are made up of a special kind of voltage-gated Ion channels producing action potential. The channels are closed even when their membrane potential is near what is the limit of the cell but when the membrane potential rises then the channels become active. As the channels become open, they allow for an inward flow sodium ions. This can increase their membrane voltage. The swift inward flow of sodium ions causes a change in the polarity of the membrane and in turn, they disappear. The potassium channels after that are activated , and there is an outward flow of the potassium ions due to which the membrane returns back to its normal state. A transient , negative shift known as refractory period prevents back movement of the action potential. In the cells of animals, generally two types of potentials are acknowledged, one is generated via voltage-gated channels and the second that is produced due to voltage-gated calcium channels.

Most cells have the voltage of their outside and indoor environment. The voltage of a cell is measured in millivolts (mV). The typical voltage for an animal cell is -70mV. In most cells, no voltage fluctuations are known as occurring, however in certain cells this may be a common feature. Certain cells can also exhibit periodic up and down oscillations as the voltage fluctuates. The duration of these potentials can vary widely. In brain cells the up and down cycle of the action potential is accomplished in less than one thousandth of a second, whereas in other cells, these cycles may take several seconds. The electrical ability of a cell in the animal kingdom is dependent upon the membrane structure. Cell membranes are composed of the lipid layer as well as proteins. The lipid layer functions as an insulation.

All animal cells are electrically polarized since they have the voltage differential known as membrane potential. For neuronal cells, axons and the cell body possess different electrical properties. The most excitable component of a neuron is the axon hillock, however, axons as well as cells body also get excited. At the axon hillock the resting potential is -70 mV and the threshold potential is at -55 MV. The synaptic inputs to the neurons result in depolarization which causes membrane potential to increase or fall. Action potential is produced when enough depolarization has occurred and the membrane potential crosses an upper limit.

Action potential is the outcome of activity of voltage-gated ion channels present in the plasma membrane of a cell. A voltage-gated , ion channel is actually a cluster composed of proteins that remain within the plasma membrane. They produce action potential as it may generate a positive feedback loop. Membrane potential is the main factor responsible for control of the activity of ion channels. Action potential is generated in the event that the positive feedback process occurs at full strength. The time and the intensity are dependent on the bio-physical properties of the ion channels with voltage-gated voltage. Different types of ion channels are known to produce positive feedback and cause the creation of these potentials. Voltage-gated sodium channels play a role with the creation of higher impulses like nerve impulses. Lesser ones, such as those created in muscle cells are controlled by calcium Ion channels.The most researched voltage-gated channel are sodium channels, which play a role in quicker nerve impulse conduction.
