An action potential occurs during which the membrane power of a cell first increases but then decreases. It is an characteristic characteristic that is present in a wide variety of cell types in animals, such as muscles, neurons and the endocrine cell. Some plant cells also produce them. Neurons play an important function in cell-to-cell communication. Beta cells of the pancreas action potentials are associated with hormone release. Plasma membrane has special type of ion channels that are voltage-gated for creating action potential. These channels are shut once the membrane's voltage is near it's resting value of the cell . However if the membrane potential increases and the channels begin to open, they become active. When the channels become active, they allow an inward flow of sodium ions, which increase its membrane potential. The rapid flow inward of sodium ions results in changing the membrane's polarity and , consequently, they cease to function. Following that, potassium channels are active and you can see an outward movement of potassium ions . Upon this, the membrane returns back to its original position. A transient negative shift referred to as refractory period blocks back movement of the action potential. In animal cells , typically two varieties of these possibles are recognized, for instance, one which is triggered through voltage-gated sodium channels and the other which occurs due to voltage-gated calcium channels.

The majority of cells have the same voltage between their interior and exterior environment. The voltage of a cell is measured in millivolts (mV). The voltage of a typical animal cell is about -70 mV. In most cells, no voltage fluctuations are known as occurring, however in certain cells, this is a common feature. Some cells also show up and down cycles as the voltage goes up and down. The time between these potentials vary over a wide range. In brain cells the down and up cycle of action potential are executed in less then a 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 influenced by the membrane structure. Cell membrane is comprised of an outer layer of lipids as well as proteins. The lipid layer serves as an insulation.

All animal cells are electrically polarized . They maintain the voltage differential called membrane potential. For neurons, , dendrites and cells have distinct electrical properties. Most excitable portion of an neuron is its axon hillock. However, the axon and body can also be stimulated. At the axon hillock the threshold potential for resting is -70mV and the threshold is 55 mgV. Synaptic stimulation to the neuron trigger depolarization which causes the membrane potential to increase or decrease. An action potential is created once enough depolarization builds up until that membrane potential reaches an upper limit.

The action potential results that voltage-gated ion channels that are found in the plasma membrane of cells. The voltage-gated ion channel actually a cluster made of proteins. They remain within the plasma membrane. They produce movement potential because it is able to create a positive feedback loop. Membrane Potential is responsible for monitoring the status of Ion channels. Action potential is generated in the event that the positive feedback process is carried out at full force. The frequency and duration are controlled by the bio-physical characteristics associated with the voltage-gated ion channel. Many kinds of ionchannels are known to produce positive feedback loops and eventually lead to the generation of these potentials. These sodium channels are involved in the creation of more powerful potentials similar to nerve impulses. More slow ones such as those produced in the muscles are controlled by calcium Ion channels.The most studied voltage-gated ion channels are the sodium ion networks that play an important role in higher speed nerve impulse transmission.
