Action potential is an occurrence that causes the membrane potential of a cell initially increases then decreases. It is a common characteristic for a range of animal cells , namely muscles, neurons, and endocrin cells. Some plant cells also produce them. Neurons play an important part in cell-to cell communication. Beta cells of the pancreas action potentials are linked with an insulin release. Plasma membrane has special type of voltage-gated ion channels that are responsible for creating action potential. These channels are shut as long as the potential of the membrane is near those of the cell , but when the membrane's voltage increases then the channels open. When the channels are inactive, they permit an inward flow of sodium ions that boost the membrane potential. The swift inward flow of sodium ions results in changing the membrane's polarity and as a result they cease to function. Following that, potassium channels are active and then there's an outward flowing of the potassium ions due to which the membrane returns to its original state. The transient shift in negative known as refractory periods prevents back forward motion of an action potential. In animal cells , typically two kinds of these voltages are recognized, for instance, one which is produced because of voltage-gated sodium channels and the second that results from voltage-gated calcium channels.

Nearly all cells keep the same voltage between their surroundings and their interior. The cell's voltage is measured in milli volts (mV). The typical voltage for an animal cell is around -70 mV. In most cells, small voltage fluctuations are reported to occur , however in certain cells this may be a common characteristic. Some cells also display fluctuations in voltage as the voltage rises and falls. The duration of these voltages differ across a broad range. In brain cells the up and down cycle of the action potential is completed in less than a thousandth of a second. However, in other cells, these cycles could take several seconds. The electrical characteristic of a cell in the animal kingdom is dependent upon the membrane structure. Cell membrane is comprised of one layer of lipids along with proteins. The lipid layer functions as an insulation.

All animal cells are electrically polarized . They maintain a voltage difference known as membrane potential. In case of neuronal cells, axons as well as the cell body have various electrical characteristics. The most excitable part of neurons is the axon hillock, however, axons as well as cells body can also be excited. At the axon , the resting potential is -70mV and the threshold is 55 MV. Neuronal synaptic interactions trigger depolarization which causes the membrane potential to rise or fall. Action potential is produced when enough depolarization has occurred and the membrane voltage reaches an upper limit.

The action potential results from the voltage-gated channels found within the plasma membranes of cells. A voltage-gated , ion channel is in fact a collection made of proteins. They remain within the plasma membrane. They produce an action potential since it could cause positive feedback loop. Membrane current is responsible control of the activity of ion channels. Action potential is generated when the positive feedback cycle occurs at full strength. The time and amplitude are controlled by the bio-physical characteristics of the voltage-gated ionchannels. Many types of ion channels have been discovered that cause positive feedback cycles that eventually produce these potentials. Voltage-gated sodium channel are involved in the generation of stronger possibles that resemble those produced by nerve impulse. In contrast, the slower ones produced in the muscles are controlled by the calcium ion channels.The most thoroughly studied voltage-gated Ion channels are sodium ion channels that are involved in more rapid nerve impulse conduction.
