An action potential occurs that occurs when the membrane potential for a specific cell initially increases but then decreases. It is the characteristic property and characteristic of a lot of animals, including muscle cells, neural cells, and the endocrine cells. Plant cells also produce them. Neurons play a crucial role in cell-to-cell communication. In beta cells of pancreas action potentials are associated with an insulin release. Plasma membranes comprise a particular kind of voltage-gated ion channels that are responsible for producing action potential. The channels are closed when the membrane potential is within that of the cell but when the membrane potential rises it opens the channels. If the channels are open, they allow an inward flow of sodium ions. This in turn increases the membrane potential. The fast inward flow of sodium ions changes the polarity of the membrane and they turn off. Following this, potassium channels become active and it is a flow of the potassium ions , causing the membrane is returned in its normal state. A temporary negative shift, known as refractory period blocks back travel of the action potential. In animal cells generally two kinds of these potentials are in existence, one of which is created via voltage-gated channels and another one that is caused by calcium channels that are voltage-gated.

Most cells have a voltage difference between their internal and external environments. The voltage of a cell is measured in millivolts (mV). The typical voltage of an animal cell is around -70 mV. In the majority of cells minimal voltage fluctuations have been observed as occurring, however in certain cells this may be a common feature. Some cells show upward and downward cycles as the voltage decreases and increases. The duration of these potentials are variable across a variety of. In brain cells the down and up cycles of action potentials are completed in less than thousandth of a second while in other cells, the cycles may take several seconds. The electrical ability of an animal cell is influenced by the membrane structure. Cell membrane is comprised of one layer of lipids along with 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, axons, dendrites and cell bodies have different electrical properties. The most stimulated part of neuron is called the axon hillock, however, axons as well as cells body also get excited. At the axon , the resting potential is 70 mV and the threshold is 55 MV. Synaptic messages to the brain induce depolarization and cause the membrane potential to rise or fall. The action potential is generated when enough depolarization has occurred and the membrane voltage reaches the threshold.

Action potential is the outcome that voltage-gated ion channels present in the plasma membrane of cells. The voltage-gated ion channel actually a group of proteins that remain embedded in plasma membrane and produces an action potential in order to give rise to an positive feedback loop. Membrane potential is responsible for maintaining the state of the Ion channels. The action potential is created in the event that the positive feedback process runs at full speed. The duration and intensity are determined by the bio-physical properties of the ion-channels that are voltage-gated. Many kinds of ionchannels are identified that generate positive feedback cycles , which eventually create these potentials. Voltage-gated sodium channels are involved with the creation of higher potentials similar to nerve impulses. These are the ones that are slower, similar to those found in muscles are controlled by calcium ion channels.The most studied voltage-gated Ion channels are the sodium-ion channels that contribute to greater speed of nerve impulse conduction.
