Action potential is a phenomenon that causes the membrane potential of a living cell first increases and then decreases. It is a signature characteristic of a variety of cell types in animals, such as muscles cells, neurons and cell types that are endocrine. Plant cells also produce these. Neurons play an extremely important part in cell-to cell communication. in pancreas beta cell action potentials are connected to that release of insulin. Plasma membrane has special type of voltage-gated ion channel for creating action potential. They remain closed whenever the membrane's potential remains close to what is the limit of the cell , but when the membrane potential rises it opens the channels. As the channels become open, they allow an inward flow sodium ions. This in turn increases cell membrane power. The swift inward flow of sodium ions changes the polarity of the membrane and , consequently, they turn off. Following this, potassium channels become activated and inward flows potassium ions , causing the membrane is returned to its original state. The transient shift in negative known as refractory period prevents back traveling of the action voltage. In animal cells typically two kinds of these potentials are well-known, such as one that is caused through voltage-gated sodium channels, while the other occurs due to calcium channels that are voltage-gated.

Most cells have an electric field between their surroundings and their interior. The voltage of a cell is measured in milli volts (mV). The typical voltage of an animal cell is -70 mV. In majority of cells very low voltage variations are thought for their existence, but in some cells this may be a common characteristic. Some cells also show the cycle of up and down as the voltage rises and falls. The time between these potentials vary over a wide range. In brain cells the down and up action potential cycle is completed in less than a thousandth of a second. However, in different types of cells, the cycle may last for several seconds. The electrical function of a cell in the animal kingdom is dependent upon the membrane structure. The cell membrane is composed of two layers of lipids and proteins. The lipid layer serves as an insulator.

All animal cells are electrically polarized , as they sustain an electrical voltage that is known as membrane potential. In case of dendrites, neurons, axons and cell bodies have different electrical characteristics. The most excitable part of a neuron is the axon hillock, but the axon and the cell body can also be excited. In the axon hillock, the resting potential is -70mV and the threshold potential is at -55 millivolts. Synaptic inputs into the neuron cause depolarization, which causes the membrane potential to increase or decrease. An action potential is created once enough depolarization occurs and the membrane voltage reaches an upper limit.

The action potential results of the activity of voltage-gated ion channels found within the plasma membranes of cells. A voltage-gated , ion channel is actually a group of proteins that are embedded inside the plasma membrane. These proteins produce an action potential in order to be the cause of the positive feedback loop. Membrane current is responsible control of the activity of ion channels. Action potential is generated whenever the positive feedback proceeds with full intensity. The time and amplitude are determined by the bio-physical properties of the voltage-gated ion channels. Several types of ion channels are identified that generate positive feedback cycles , which eventually lead to the generation of these potentials. The sodium channels that are voltage-gated participate in the generation of larger potentials that are similar to nerve impulses. More slow ones such as those produced in muscle cells are mediated by calcium Ion channels.The ones that have been the most extensively studied voltage -gated channel are sodium ion channels that are involved in higher speed nerve impulse transmission.
