Action potential is a phenomenon where the membrane potential of a living cell first increases before decreasing. It is a typical characteristic and characteristic of a lot of animal cells , including muscles cells, nerve cells, and endocrinological cells. Plant cells also produce them. Neurons play an essential role in cell-tocell communication. In pancreas beta cells, the action potential is associated with that release of insulin. Plasma membrane has a particular type of ion channels with voltage-gated voltages for creating action potential. The channels remain closed when the membrane potential is near those of the cell but should the membrane potential increase it opens the channels. When the channels are inactive, they let inward flow sodium ions. This increases its membrane potential. The rapid inward flow sodium ions results in changing the membrane's polarity and consequently they cease to function. The potassium channels after that are active and inward flows of potassium ions . As a result, the membrane returns back to its original position. A transient , negative shift known as refractory periods prevents back travelling of the action potential. In animal cells , typically two kinds of these voltages are known for example, one which is produced due to the voltage-gated sodium channels, and one that occurs due to calcium channels that are voltage-gated.

Nearly all cells keep an electric field between their surroundings and their interior. The voltage of the cell is measured in millivolts (mV). The typical voltage for an animal cell is -70mV. In the majority of cells tiny voltage fluctuations are observed to occur but in some cells this is an expected feature. Certain cells can also exhibit variations in the voltage, as they increase and decrease in voltage. The time between these potentials can be varied over a broad spectrum. In brain cells the down and up action potential cycle is performed in less than a thousandth of a second. However, in other cells, the processes can last several seconds. The electrical power of an animal cell is dependent on the membrane structure. Cell membrane is comprised of layers of lipids, and proteins. The lipid layer acts as an insulation.

Animal cells are all electrically polarized since they have an electric voltage which is known as membrane potential. In case of dendrites, neurons, axons and cell bodies have different electrical characteristics. The most excitable part of an neuron is its axon hillock, but the axon and the cell body can also be stimulated. The axon hillock's resting potential is -70mV and the threshold is at -55 MV. Synaptic messages to the brain result in depolarization causing the membrane potential to increase or decrease. A potential for action is created when sufficient depolarization takes place and the membrane potential crosses the threshold.

The action potential results from the voltage-gated channels that are found in the plasma membrane of cells. An ion channel that is voltage-gated is actually a cluster of proteins , which are encased within the plasma membrane. They produce movement potential because it is able to give rise to an positive feedback loop. Membrane potential is accountable for controlling the level of Ion channels. Action potential is generated when the positive feedback cycle continues at its fullest. The time and the intensity are dependent on the bio-physical properties of the voltage-gated ion channels. Different types of ion channels are known to produce positive feedback loops and eventually lead to the generation of these potentials. Voltage-gated sodium channels play a role in the generation of stronger potentials similar to nerve impulse. In contrast, the slower ones produced in the muscle cells are mediated by calcium Ion channels.The most rigorously researched voltage-gated ion channels are the sodium ion channels participating in greater speed of nerve impulse conduction.
