A process called an action potential happens that occurs when the membrane potential of a cell initially increases before decreasing. It is the characteristic property of several cell types in animals, such as muscle cells, neurons, and cell types that are endocrine. Plant cells also produce these. Neurons play a crucial role in cell-tocell communications. Beta cells of the pancreas the action potential is associated with the release of insulin. Plasma membranes are made up of a special kind in voltage-gated, ion-channels that are used for creating action potential. The channels are closed even when their membrane potential is close to an equilibrium potential for the cell , but If the membrane's current potential rises then the channels will become active. When the channels open they allow the flow of sodium ions, which increase the cell's membrane potency. The rapid inward flow of sodium ions alters the polarity of the membrane and in turn, they turn off. In the following, potassium channels become activated , and inward flows of potassium ions . The result is that the membrane returns back to its normal state. A transient positive shift known as refractory period prevents back motion of the potential. In the animal cell, generally two types of these potentials are recognized, for instance, one is generated due to the voltage-gated sodium channels and the other which can be produced by voltage-gated calcium channels.

The majority of cells exhibit some degree of voltage variation between their environment and their inside. The voltage of the cell is measured in milli volts (mV). The voltage of a typical animal cell is around -70 mV. In the majority of cells minimal voltage fluctuations have been observed to occur however in some cells, this is a standard characteristic. Certain cells also exhibit the cycle of up and down as the voltage increases and declines. The duration of these potentials are variable across a variety of. In brain cells the down and up phase of an action potential are complete in less than the thousandth of a second. However, in other cells, these actions can last for a long time. The electrical capacity of a cell in the animal kingdom is influenced by the membrane structure. Cell membrane is comprised of layers of lipids and proteins. The lipid layer functions as an insulator.

All animal cells are electrically polarized . They maintain the difference in voltage known as membrane potential. In case of neurons, axonsand dendrites and the cell body all have different electrical characteristics. One of the most exciting parts of an individual neuron is the hillock but axon and cell body are also excited. At the axon , the resting current is around 70 mV and the threshold potential is at -55 millivolts. Synaptic inputs to the neuron trigger depolarization which causes the membrane potential to increase or decrease. Action potentials are produced when sufficient depolarization takes place and the membrane's potential exceeds the threshold.

Action potential is the result of the activity of voltage-gated ion channels in the plasma membranes of cells. The voltage-gated ion channel actually a group consisting of proteins that stay in the plasma membrane. It produces motion potential because it can generate a positive feedback loop. Membrane potential is the main factor responsible for controlling the state of Ion channels. The action potential is created when the feedback cycle runs at full speed. The time and amplitude of the action are dependent on the bio-physical properties of the voltage-gated ion channels. Numerous types of ion-channels have been discovered that cause positive feedback cycles that eventually result in the production of these potentials. They are involved in the creation of fast possibles that resemble those produced by nerve impulses. Slower ones like those produced in the muscle cells are controlled by the calcium ion channels.The most studied voltage-gated Ion channels are sodium ion channels participating in the faster conduction of nerve impulses.
