Action potential is an occurrence that occurs when the membrane potential of a cell initially increases but then decreases. It is a characteristic property of several animal cells namely, muscles, neurons, and endocrine cells. Certain plant cells also produce these. Neurons play a significant role in cell-to-cell communication. Pancreas beta cells have beta cells. actions potential is associated with in the production of insulin. Plasma membranes have a specific type in voltage-gated, ion-channels that are used for producing action potential. The channels are closed when the membrane potential is near an equilibrium potential for the cell but If the membrane's current potential rises then the channels will become active. When the channels become active, they allow an inward flow of sodium ions that increase cell membrane power. The fast inward flow of sodium ions result in changing the polarity of the membrane and consequently they are inactive. Following that, potassium channels are active and you can see an outward movement of potassium ions . Upon this, the membrane is returned back to its normal state. The transient shift in negative known as refractory is a way to stop back motion of the potential. In animal cells , two kinds of these voltages are known for example, one that is caused by voltage-gated sodium channels, the other is generated by calcium channels that are voltage-gated.

Nearly all cells show the voltage of their exterior and interior environments. 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, minor voltage fluctuations are observed to occur but in some cells, this is a common feature. Cells can show up and down cycles as the voltage fluctuates. The duration of these voltages vary throughout a vast range. In brain cells, the up and down process of action possible are completed in less that a thousandth of a second. In different types of cells, the sequences can take as long as a couple of seconds. The electrical properties of a cell in the animal kingdom is dependent on its membrane structure. Cell membranes are composed of an outer layer of lipids as well as proteins. The lipid layer functions as an insulation.

Animal cells are all electro-polarized. They keep a voltage difference known as membrane potential. In case of cells, neurons and axons, dendrites and cell body have different electrical characteristics. The most excitable part of neuron is the axon hillock. However, the axon and body are also excited. The axon hillock's resting potential is -70 mV and the threshold potential is -55 mV. Synaptic signals to the neuron result in depolarization that causes the membrane potential to rise or decrease. The action potential is generated when enough depolarization builds up until the membrane potential exceeds an upper limit.

Action potential is the result on the activities of voltage-gated channels present in the plasma membrane of cells. A voltage-gated , ion channel is actually a group consisting of proteins that stay inside the plasma membrane. These proteins produce action potential because it can give rise to an positive feedback loop. Membrane potential is responsible for managing the state of these channels. The action potential is created in the event that the positive feedback process occurs at full strength. The duration as well as the magnitude are determined by the biophysical properties of the ion channels with voltage-gated voltage. Ion channels of various types are recognized that create positive feedback cycles and ultimately cause the creation of these potentials. These sodium channels are involved in the creation of fast impulses like nerve impulse. In contrast, the slower ones produced in the muscles are controlled by the calcium Ion channels.The most intensively studied voltage-gated channel are sodium ion channels which are involved in greater speed of nerve impulse conduction.
