Action potential is an event in which the potential of the membrane of a cell increases before decreasing. It is a typical characteristic for a range of animal cells , namely muscle cells, neuron cells, and endocrine cells. Some plant cells also produce these. Neurons play a vital function in cell-to-cell communication. in pancreas beta cell the action potential is associated with production of insulin. Plasma membranes have a specific type of voltage-gated ion channels for producing action potential. They remain closed as long as the potential of the membrane is within the resting potential of the cell , but when the membrane's potential increases and the channels begin to open, they become active. As the channels become open, they permit an inward flow of sodium ions that boost their membrane voltage. The rapid inward flow sodium ions changes the polarity of the membrane and , in the process, are inactive. After this, potassium channels get active and the flow outward of potassium ions . This causes the membrane returns to its normal state. A transient negative shift referred to as refractory is a way to stop back travel of the action potential. In the animal cell, generally two types of these potentials are known for example, one of which is created by voltage-gated sodium channels, the other is caused by calcium channels that are voltage-gated.

Nearly all cells maintain the voltage of their internal and external environments. The voltage of the cell is measured in milli volts (mV). The typical voltage of an animal cell is about -70 mV. The majority of cells show little voltage fluctuations are known for their existence, but in some cells this is a typical feature. Some cells show fluctuations in voltage as they increase and decrease in voltage. The duration of these voltages are variable across a variety of. In brain cells the up and down sequence of action potentials are complete in less than the thousandth of a second, whereas in other cells, the cycle may last for several seconds. The electrical characteristic of an animal cell depends on the membrane structure. Cell membrane is made up of a layer of lipids and proteins. The lipid layer functions as an insulation.

Animal cells are all electrically polarized because they keep an electrical voltage that is known as membrane potential. For neurons, dendrites, axons and the body of the cell have distinct electrical characteristics. The most excitable component of neuron is the Axon hillock, however the axon as well as the cell body can also be excited. In the axon hillock, the resting potential is 70 mV and the threshold is at -55 mV. The synaptic inputs to the neurons result in depolarization which causes membrane potential to increase or decrease. Action potential is created when enough depolarization happens and the membrane current reaches an upper limit.

The action potential results by the action of voltage-gated channels within the plasma membrane of a cell. A voltage-gated ion channel is in fact a collection made of proteins. They remain in the plasma membrane. It generates motion potential because it can cause a positive feedback loop. Membrane power is responsible for control of the activity of ion channels. Action potential is generated during the time that the feedback cycle continues at its fullest. The time and amplitude of the action are determined by the biophysical properties of the voltage-gated ion channels. Several types of ion channels are identified that generate positive feedback mechanisms and lead to the generation of these potentials. Voltage-gated sodium-channels are involved with the creation of higher potentials like those of nerve impulse. More slow ones such as those produced by muscles cells are controlled by calcium Ion channels.The most researched voltage-gated Ion channels are sodium ion channels that are involved in the faster conduction of nerve impulses.
