A process called an action potential happens in which the potential of the membrane of a cell initially increases and then decreases. It is a characteristic feature and characteristic of a lot of animal cells , including muscles, neurons and endocrinological cells. Certain plant cells also produce them. Neurons play an extremely important role in cell-tocell communication. Pancreas beta cells have beta cells. actions potential is associated with that release of insulin. Plasma membranes are made up of a special kind of voltage-gated channels for producing action potential. These channels are shut even when their membrane potential is within what is the limit of the cell . However, when the membrane's potential increases it becomes active. When they are opened, they allow an inward flow sodium ions which increases your membrane's potential. The fast inward flow of sodium ions can alter the polarity of the membrane and in turn, they disappear. After that potassium channels become active and they are able to flow outward of the potassium ions . Upon this, the membrane returns to its original state. A temporary negative shift, known as refractory duration prevents the reverse running of the action kinetic. In animal cells typically two kinds of these are described, for instance, one of which is created via voltage-gated channels, the other is produced due to voltage-gated calcium channels.

A majority of cells experience an electrical voltage gap between their surroundings and their interior. The voltage of the cell is measured in millivolts (mV). The typical voltage of an animal cell is -70mV. Most cells have small voltage fluctuations are reported as occurring, however in certain cells this is an expected feature. Some cells show oscillations between up and down when the voltage decreases and increases. The duration of these potentials can vary widely. In brain cells the down and up action potential cycle is complete in less than the thousandth of a second, whereas in other types of cells , cycles can take up to a few seconds. The electrical properties of an animal cell depends on the membrane structure. Cell membranes consist of a layer of lipids and proteins. The lipid layer serves as an insulation.

All animal cells are electrically polarized because they keep an electric charge that is called membrane potential. In case of neurons, axons, dendrites and cell body have different electrical characteristics. The most exuberant part of one's neuron's axon hillock. However, the axon and body also get excited. At the axon , the resting current is around 70 mV and the threshold voltage is -55 millivolts. Synaptic messages to the brain cause depolarization, which causes the membrane potential to rise or decrease. The action potential is generated when enough depolarization happens and the membrane potential exceeds the threshold.

Action potential is the outcome from the voltage-gated channels present in the plasma membrane of a cell. Ion channels that are voltage-gated are actually a cluster made of proteins. They remain in the plasma and produce action potential because it can generate the 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 ion-channels that are voltage-gated. Different types of ion channels exist that can generate positive feedback cycles and ultimately create these potentials. Voltage-gated sodium channels are involved in the creation of fast potentials , similar to those that result from nerve impulse. The slower ones, like those generated in the muscle cells are controlled by calcium ion channels.The most rigorously researched voltage-gated Ion channels are sodium ion channels that are involved in the faster conduction of nerve impulses.
