Action potential is a phenomenon where the membrane potential of a particular cell increases then decreases. It is a characteristic feature that is present in a wide variety of animal cells including neurons, muscle cells and the endocrine cell. Some plant cells also make them. Neurons play an extremely important role in cell-tocell communication. In beta cells of pancreas action potentials are associated with an insulin release. Plasma membrane has special type of ion channels that are voltage-gated for creating action potential. These channels are shut whenever the membrane's potential remains close to an equilibrium potential for the cell . However, when the membrane's potential is increased then the channels open. The channels that are active allow for an inward flow sodium ions that increase the membrane potential. The rapid inward flow sodium ions causes a change in the polarity of the membrane and , in the process, stop functioning. After that potassium channels become activated and it is a flow potassium ions . Upon this, the membrane returns to its resting condition. A transient positive shift known as refractory interval prevents further forward motion of an action potential. In animal cells generally two kinds of these potentials are acknowledged, one because of voltage-gated sodium channels, and one that is generated by calcium channels that are voltage-gated.

The majority of cells exhibit an electric field between their surroundings and their interior. The cell's voltage is measured in millivolts (mV). The typical voltage of an animal cell is around -70 mV. Most cells have little voltage fluctuations are known to happen, but in a few cells this is a usual characteristic. Some cells show periodic up and down oscillations as the voltage drops and increases. The duration of these potentials can vary widely. In brain cells, the up and down phase of an action potential are completed in less than thousandth of a second. In other cells, actions can last for a long time. The electrical characteristic of an animal cell is influenced by the membrane structure. Cell membranes consist of an lipid layer and proteins. The lipid layer serves as an insulator.

All animal cells are electrically polarized and maintain an electric charge that is known as membrane potential. In case of neurons, dendrites, axons and cells have distinct electrical characteristics. The most exuberant part of one's neuron's axon hillock. However, the axon and body are also excited. At the axon hillock the remaining potential is -70mV and the threshold is at -55 mV. Neuronal synaptic interactions result in depolarization which causes membrane potential to rise or fall. It is produced when enough depolarization builds up until the membrane potential reaches the threshold.

Action potential is the outcome of the activity of voltage-gated ion channels which are located within the plasma membrane of cells. The voltage-gated ion channel in fact a collection of proteins , which are encased inside the plasma membrane. These proteins produce actions potential due to the fact that it could create the positive feedback loop. Membrane current is responsible controlling the condition of ion channels. The action potential is created when the feedback cycle continues at its fullest. The duration as well as the magnitude are controlled by the bio-physical characteristics associated with the voltage-gated ion channel. Different types of ion channels are known to produce positive feedback cycles , which eventually produce these potentials. They are involved in the generation of higher-frequency possibles that resemble those produced by nerve impulse. The slower ones, like those generated by muscle cells are controlled by the calcium ion channels.The most extensively studied voltage-gated Ion channels are sodium-ion channels that contribute to greater speed of nerve impulse conduction.
