An action potential occurs during which the membrane power for a specific cell initially increases before decreasing. It is the characteristic property of several cell types in animals, such as neurons, muscle cells and the endocrine cell. Plant cells can also produce them. Neurons play the most important role in cell-tocell communication. In beta cells of pancreas the action potential is associated with that release of insulin. Plasma membrane has special type of ion channels that are voltage-gated for producing action potential. The channels remain closed as long as the potential of the membrane is near an equilibrium potential for the cell , but when the membrane's potential is increased then the channels open. When the channels open they allow for an inward flow sodium ions, which increase its membrane potential. The swift inward flow of sodium ions can alter the membrane's polarity and in turn, they are inactive. Following this, potassium channels become activated and inward flows of the potassium ions , causing the membrane returns to its normal state. A transient negative shift , also known as the refractory phase prevents the return travelling of the action potential. In the animal cell, generally two kinds of these potentials can be well-known, such as one which is produced because of voltage-gated sodium channels and the other which results from voltage-gated calcium channels.

Nearly all cells keep a voltage difference between their surroundings and their interior. The voltage of a cell is measured in milli volts (mV). The typical voltage of an animal cell is -70 mV. In most cells, few voltage fluctuations are believed as occurring, however in certain cells this can be a normal characteristic. Some cells also show up and down cycles as the voltage fluctuates. The time between these potentials vary over a wide range. In brain cells the down and up cycle of the action potential is accomplished in less than one thousandth of a second. In other types of cells , cycles may take several seconds. The electrical properties of an animal cell depends on the membrane structure. Cell membrane is made up of an lipid layer and proteins. The lipid layer acts as an insulation.

Animal cells are all electro-polarized. They keep the same voltage, also called membrane potential. In case of the neurons, dendrites and the cell body possess different electrical characteristics. The most stimulated part of neuron is called the axon hillock, but the axon and the cell body also get excited. At the axon hillock the resting current is around 70 mV and the threshold voltage is 55 MV. Synaptic signals to the neuron trigger depolarization which causes the membrane potential to rise or fall. A potential for action is created when enough depolarization builds up until the membrane potential reaches the threshold.

Action potential is the outcome on the activities of voltage-gated channels in the plasma membranes of cells. A voltage-gated Ion Channel is in fact a collection of proteins that remain embedded in the plasma membrane. This produces action potential as it may generate the positive feedback loop. Membrane Potential is responsible for control of the activity of these channels. The action potential is created when the positive feedback cycle gets full power. Its duration and amplitude are controlled by the bio-physical characteristics of the ion-channels that are voltage-gated. There are a variety of ion channel types that are available that are believed to generate positive feedback cycles , which eventually create these potentials. Voltage-gated sodium channels are involved with the creation of higher impulses like nerve impulse. In contrast, the slower ones produced in the muscle cells are controlled by the calcium ion channels.The most researched voltage-gated channel are sodium ion channels which are involved in more rapid nerve impulse conduction.
