An action potential occurs where the membrane potential for a specific cell initially increases but then decreases. It is a characteristic property for a range of animal cells , including muscles, neurons, and endocrinological cells. Plant cells also produce these. Neurons play an essential role in cell-tocell communications. Pancreas beta cells have beta cells. action potential is associated with the release of insulin. Plasma membranes feature a unique type of ion channels with voltage-gated voltages for creating action potential. They remain closed at times when membrane potential is within the potential at rest of the cell , but in the event that the membrane potential grows and the channels begin to open, they become active. As the channels become open, they permit an inward flow of sodium ions which increases the cell's membrane potency. The rapid flow of sodium ions alters the polarity of the membrane and , consequently, they disappear. In the following, potassium channels become active and the flow outward of the potassium ions . The result is that the membrane returns to its original state. A transient , negative shift known as refractory periods prevents back traveling of the action voltage. In animal cells typically two kinds of these voltages are known for example, one of which is through voltage-gated sodium channels, while the other is generated by voltage-gated calcium channels.

Most cells have in a voltage differential between their interior and exterior environment. The voltage of the cell is measured in millivolts (mV). The typical voltage of an animal cell is around -70 mV. In the majority of cells, tiny voltage fluctuations are observed to occur but in some cells, this is a standard characteristic. Certain cells also exhibit an up-and-down cycle as the voltage drops and increases. The time between these potentials vary over a wide range. In brain cells the down and up phase of an action potential are performed in less than a thousandth of a second. However, in other types of cells the cycles could take several seconds. The electrical function of a cell in the animal kingdom is influenced by the membrane structure. Cell membranes are composed of layers of lipids, and proteins. The lipid layer acts as an insulator.

All animal cells are electrically polarized due to the voltage differential known as membrane potential. For neurons, axons, dendrites and cell bodies have different electrical characteristics. The most excitable part of neuron is the Axon hillock but axon and cell body can also be excited. In the axon hillock, the resting potential is -70 mV and the threshold voltage is 55 mV. Synaptic inputs into the neuron induce depolarization and cause the membrane potential to rise or decrease. Action potential is produced when enough depolarization accumulates and the membrane current reaches an upper limit.

The action potential results on the activities of voltage-gated channels located in the plasma membrane of a cell. The voltage-gated ion channel in fact a collection of proteins that remains embedded inside the plasma membrane. These proteins produce an action potential in order to cause an positive feedback loop. Membrane potential is accountable for controlling the condition of these channels. Action potential is generated by the positive feedback cycle that is carried out at full force. The time and amplitude are determined by the bio-physical properties of the ion channel voltage-gated. Numerous types of ion-channels have been discovered that cause positive feedback processes that cause the creation of these potentials. The sodium channels that are voltage-gated participate in the generation of stronger impulses like nerve impulse. Slower ones , like those made by muscle cells are mediated by the calcium ion channels.The most studied voltage-gated ion channels are the sodium ion channels that are involved in the speedier nerve impulse conduction.
