An action potential occurs where the potential for the membrane of a cell initially increases before decreasing. It is a characteristic feature of many cell types in animals, such as muscle cells, neuron cells, and hormone-producing cells. Plant cells also produce them. Neurons play an extremely important role in cell-tocell communications. The beta cells of the pancreas action potentials are connected to the release of insulin. Plasma membranes contain a distinct type of voltage-gated ion channels that are responsible for producing action potential. The channels are closed as long as the potential of the membrane is within the potential at rest of the cell but If the membrane's current potential rises then the channels are activated. The channels that are active allow for an inward flow sodium ions which increases their membrane voltage. The rapid inward flow sodium ions leads to a change in the polarity of the membrane and consequently they are inactive. In the following, potassium channels become active and inward flows of potassium ions . Upon this, the membrane is returned to its normal state. A temporary negative shift, known as refractory is a way to stop back motion of the potential. In animal cells , two types of these potentials are well-known, such as one which is triggered due to voltage-gated sodium channels, and another that is generated by voltage-gated calcium channels.

In most cells, there is some degree of voltage variation between their surroundings and their interior. The voltage of the cell is measured in milli volts (mV). The voltage of a typical animal cell is around -70 mV. In most cells, minimal voltage fluctuations have been observed to occur however in some cells, this is a common characteristic. Certain cells may also exhibit the cycle of up and down as they increase and decrease in voltage. The duration of these potentials vary throughout a vast range. In brain cells, the up and down sequence of action potentials are accomplished in less than one thousandth of a second. In other cell types, the sequences can take as long as a couple of seconds. The electrical property of an animal cell is dependent on its membrane structure. Cell membranes are composed of an lipid layer and proteins. The lipid layer serves as an insulation.

All animal cells are electrically polarized and maintain a voltage difference called membrane potential. For neurons, axonsand dendrites and the body of the cell have distinct electrical properties. Most excitable portion of an neuron is its axon hillock. However, the axon, dendrites, and cell body also get excited. At the axon hillock the maximum resting power is -70 mV and the threshold is 55 mV. Synaptic inputs to the neuron induce depolarization and cause the membrane potential to increase or decrease. Action potentials are produced when sufficient depolarization takes place and the membrane current reaches a threshold value.

The action potential results of the activity of voltage-gated ion channels found within the plasma membrane of cells. Ion channels that are voltage-gated are actually a group of proteins , which are encased in plasma membranes and generates action potential as it may trigger an positive feedback loop. Membrane potential is accountable for monitoring the status of ion channels. The action potential is created during the time that the feedback cycle takes place at full intensity. The frequency and duration are dependent on the bio-physical properties of the voltage-gated Ion Channels. Several types of ion channels are available that are believed to generate positive feedback processes that lead to the generation of these potentials. Voltage-gated sodium channel are involved with the creation of higher impulses like nerve impulse. Slower ones like those produced in muscle cells are mediated by the calcium ion channels.The most extensively studied voltage-gated channel are sodium-ion channels that contribute to higher speed nerve impulse transmission.
