An action potential occurs in which the membrane voltage that a cell has first increases but then decreases. It is a characteristic feature for a range of human cells, which include muscle cells, neurons, and hormone-producing cells. Plant cells can also produce these. Neurons play an essential role in cell-tocell communication. In the beta pancreas cells action potentials are associated with it being released by insulin. Plasma membranes have a specific type of voltage-gated Ion channels producing action potential. The channels remain closed when the membrane potential is close to the potential at rest of the cell . However, if the membrane potential increases and the channels begin to open, they become active. If the channels are open, they permit an inward flow of sodium ions that boost its membrane potential. The rapid inward flow of sodium ions leads to a change in the membrane's polarity and in turn, they stop functioning. After that potassium channels become active and then there's an outward flowing sodium ions. Due to this, the membrane returns to its neutral state. A transient , negative shift known as refractory period prevents back movement of the action potential. In animal cells generally , two kinds of these potentials can be described, for instance, one because of voltage-gated sodium channels, and another that is generated by voltage-gated calcium channels.

Nearly all cells maintain the voltage of their exterior and interior environments. The voltage of a cell is measured in milli volts (mV). The typical voltage for an animal cell is -70mV. The majority of cells show no voltage fluctuations are known to take place, but in certain cells, this is a standard characteristic. Some cells show up and down cycles as the voltage rises and falls. The duration of these voltages vary over a wide range. In brain cells, the up and down phase of an action potential are executed in less then a thousandth of a second while in other cells, these cycles can take up to a few seconds. The electrical properties of a cell in the animal kingdom depends on the membrane structure. The cell membrane is composed of an outer layer of lipids as well as proteins. The lipid layer serves as an insulation.

All animal cells are electro-polarized. They keep the voltage differential known as membrane potential. For neurons, axonsand dendrites and the cell body possess different electrical properties. The area that is most excitable in neurons is the axon hillock. However, axons and cells body too can be stimulated. At the axon hillock the resting voltage is -70 mV and the threshold potential is -55 mgV. Synaptic connections to the nerve induce depolarization and cause the membrane potential to rise or decrease. The action potential is generated when enough depolarization has occurred and the membrane potential is at a threshold value.

Action potential is the outcome from the voltage-gated channels found within the plasma membrane of cells. The voltage-gated ion channel actually a group of proteins , which are encased inside the plasma membrane. These proteins produce movement potential because it is able to result in the positive feedback loop. Membrane potential plays a role in setting the parameters of ion channels. The action potential is created during the time that the feedback cycle goes on at full-speed. The frequency and duration are determined by the biophysical properties of the voltage-gated Ion Channels. A variety of Ion Channels are recognized that create positive feedback and result in the production of these potentials. The sodium channels that are voltage-gated participate in the generation of stronger potentials , similar to those that result from nerve impulses. Lesser ones, such as those created in the muscle cells are mediated by the calcium Ion channels.The most researched voltage-gated Ion channels are sodium-ion channels that contribute to quicker nerve impulse conduction.
