A process called an action potential happens in which the potential of the membrane that a cell has first increases and then decreases. It is an characteristic characteristic to a variety of animal cells namely, muscle cells, neuron cells, and endocrin cells. Certain plant cells also produce them. Neurons play a very crucial part in cell-to cell communication. The beta cells of the pancreas actions potential is associated with production of insulin. Plasma membranes contain a distinct type of voltage-gated Ion channels creating action potential. The channels remain closed once the membrane's voltage is close to the potential at rest of the cell . However, when the membrane's voltage increases the channels then they open. When they are opened, they permit the inward flow of sodium ions which increases your membrane's potential. The swift inward flow of sodium ions causes a change in the polarity of the membrane and , consequently, they disappear. The potassium channels then become active and there is an outward flow potassium ions . Upon this, the membrane is returned to its resting condition. A transient negative shift referred to as refractory period prevents back traveling of the action voltage. In the cells of animals, generally two kinds of these voltages are acknowledged, one of which is from voltage-gated potassium channels and the second that is generated by voltage-gated calcium channels.

The majority of cells have some degree of voltage variation between their outside and indoor environment. The cell's voltage is measured in milli volts (mV). The typical voltage for an animal cell is about -70 mV. For the vast majority of cells, little voltage fluctuations are known to happen, but in a few cells this is a usual feature. Cells can show periodic up and down oscillations as the voltage rises and falls. The duration of these potentials are variable across a variety of. In brain cells the down and up action potential cycle is completed in a fraction of a millisecond of a second while in different types of cells, the processes can last several seconds. The electrical property of an animal cell is dependent 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 electro-polarized. They keep a voltage variation called membrane potential. In case of neurons, , dendrites and the cell body possess different electrical properties. The most exuberant part of neuron is the Axon hillock, but the axon and the cell body can also be stimulated. The axon hillock's resting voltage is -70 mV and the threshold voltage is at -55 mgV. Synaptic stimulation to the neuron cause depolarization, which causes the membrane potential to rise or decrease. Action potential is produced when enough depolarization accumulates and the membrane potential reaches the threshold.

Action potential is the result of the activity of voltage-gated ion channels present in the plasma membrane of a cell. A voltage-gated ion canal is actually a cluster of proteins that are embedded inside the plasma membrane. These proteins produce movement potential because it is able to create the positive feedback loop. Membrane potential is responsible for controlling the state of ion channels. The action potential is created by the positive feedback cycle that runs at full speed. The time and amplitude are determined by the bio-physical properties of the ion-channels that are voltage-gated. Many types of ion channels are recognized that create positive feedback and result in the production of these potentials. They are involved in the generation of stronger potentials , similar to those that result from nerve impulses. The slower ones, like those generated in muscle cells are controlled by the calcium Ion channels.The most researched voltage-gated ion channels are the sodium channels, which play a role in greater speed of nerve impulse conduction.
