Action potential is an occurrence in which the membrane voltage for a specific cell initially increases then decreases. It is a characteristic property that is present in a wide variety of animal cells namely, muscles, neurons and the endocrine cell. Certain plant cells also produce these. Neurons play an important role in cell-tocell communications. In beta cells of pancreas action potentials are connected to hormone release. Plasma membranes are made up of a special kind of voltage-gated channels for creating action potential. The channels are closed once the membrane's voltage is within it's resting value of the cell . However, when the membrane potential rises and the channels begin to open, they become active. The channels that are active allow an inward flow of sodium ions. This in turn increases its membrane potential. The rapid inward flow sodium ions leads to a change in the polarity of the membrane and they disappear. After this, potassium channels get activated and the flow outward of potassium ions , causing the membrane returns to its resting state. A transient positive shift known as refractory period blocks back travel of the action potential. In animal cells generally , two types of these potentials exist, understood, one by voltage-gated sodium channels, while the other can be produced by calcium channels that are voltage-gated.

A majority of cells experience an electrical difference between their exterior and interior environments. The cell's voltage is measured in millivolts (mV). The typical voltage for an animal cell is -70mV. In the majority of cells, little voltage fluctuations are known to occur however in some cells, this is a common feature. Some cells also show an up-and-down cycle as the voltage increases and declines. The time between these potentials fluctuate over a large range. In brain cells the down and up motion potential cycle are completed in a fraction of a millisecond of a second while in other cell types, the cycles may take several seconds. The electrical activity of a cell in the animal kingdom is dependent on its membrane structure. Cell membrane is made up of an lipid layer and proteins. The lipid layer functions as an insulation.

Animal cells are all electrically polarized due to an electric voltage which is called membrane potential. In case of neurons, , dendrites as well as the cell body have various electrical properties. One of the most exciting parts of neurons is the axon hillock however axons and the cell body can also be excited. At the axon , the resting current is around 70 mV and the threshold voltage is 55 mgV. Neuronal synaptic interactions induce depolarization and cause the membrane potential to rise or decrease. Action potentials are generated when enough depolarization occurs and the membrane current reaches a threshold value.

Action potential is the outcome by the action of voltage-gated channels located in the plasma membrane of a cell. Ion channels that are voltage-gated are in fact a collection made of proteins. They remain in the plasma membrane. It generates motion potential because it can create the positive feedback loop. Membrane voltage is responsible for monitoring the status of these channels. The action potential is created whenever the positive feedback runs at full speed. The time and amplitude of the action are dependent on the bio-physical properties of the voltage-gated ionchannels. Many types of ion channels are identified that generate positive feedback mechanisms and result in the production of these potentials. Voltage-gated sodium channels are involved in the production of high-speed potentials that are similar to nerve impulses. More slow ones such as those produced by muscle cells are mediated by calcium ion channels.The most rigorously researched voltage-gated ion channels are the sodium ion channels which are involved in more rapid nerve impulse conduction.
