An action potential occurs that causes the membrane potential of a cell increases then decreases. It is an characteristic characteristic for a range of animal cells , including muscle cells, neurons, and hormone-producing cells. Plant cells also produce them. Neurons play an important role in cell-tocell communication. Beta cells of the pancreas actions potential is associated with the release of insulin. Plasma membranes are made up of a special kind of voltage-gated ion channels for creating action potential. They remain closed whenever the membrane's potential remains close to what is the limit of cells, however when the membrane potential rises then the channels open. If the channels are open, they permit the inward flow of sodium ions, which boosts the potential of membranes. The fast inward flow of sodium ions result in changing the membrane's polarity and as a result they stop functioning. The potassium channels then become active and they are able to flow outward of the potassium ions . Upon this, the membrane returns to its resting condition. The transient negative change known as refractory period prevents back moving of the action-potential. In animal cells , two types of these potentials exist, understood, one that is generated by the voltage-gated calcium channels, and another that is produced due to voltage-gated calcium channels.

In most cells, there is a voltage difference between their exterior and interior environments. The cell's voltage is measured in milli volts (mV). The voltage of a typical animal cell is -70mV. In the majority cells, tiny voltage fluctuations are observed to happen, but in a few cells, this is a common feature. Some cells exhibit upward and downward cycles as they increase and decrease in voltage. The duration of these voltages are variable across a variety of. In brain cells the down and up process of action possible are complete in less than the thousandth of a second. In other cell types, the cycles can take up to a few seconds. The electrical activity of a cell in the animal kingdom is dependent on its membrane structure. Cell membranes are composed of layers of lipids, and proteins. The lipid layer functions as an insulation.

Animal cells are all electrically polarized and maintain the difference in voltage called membrane potential. For neurons, , dendrites as well as the cell body have various electrical characteristics. The most stimulated part of a neuron is the axon hillock, however, axons as well as cells body also get excited. The axon hillock's remaining potential is -70mV and the threshold voltage is 55 millivolts. Synaptic inputs to the neuron cause depolarization, which causes the membrane potential to rise or fall. Action potential is created when sufficient depolarization takes place and the membrane current reaches a threshold value.

Action potential is the outcome of the work of voltage-gated Ion channels that are found in the plasma membranes of cells. A voltage-gated ion canal is actually a group consisting of proteins that stay in the plasma and produce an action potential in order to cause positive feedback loop. Membrane power is responsible for control of the activity of Ion channels. The action potential is created whenever the positive feedback goes on at full-speed. Its duration and amplitude are controlled by the bio-physical characteristics of the ion channels with voltage-gated voltage. There are a variety of ion channel types that exist that can generate positive feedback cycles and ultimately lead to the generation of these potentials. Voltage-gated sodium channels play a role in the creation of more powerful potentials , similar to those that result from nerve impulse. In contrast, the slower ones produced by muscle cells are mediated by calcium ion channels.The most thoroughly studied voltage-gated channel are sodium ion channel that participate in the speedier nerve impulse conduction.
