Action potential is an occurrence where the membrane potential of a particular cell increases before decreasing. It is a typical characteristic that is present in a wide variety of living cells, including neurons, muscle cells and endocrinological cells. Plant cells also produce them. Neurons play an extremely important part in cell-to cell communication. In the beta cells of the pancreas, action potentials are linked with releases of insulin. Plasma membranes feature a unique type of ion channels with voltage-gated voltages for creating action potential. The channels are closed while the membrane's current potential near what is the limit of the cell . However, in the event that the membrane potential grows then the channels open. When they are opened, they let inward flow sodium ions which increases your membrane's potential. The fast inward flow of sodium ions changes the polarity of the membrane which causes them to turn off. In the following, potassium channels become activated , and there is an outward flow of potassium ions due to which the membrane returns to its resting condition. A temporary negative shift, known as refractory time prevents the back traveling of the action voltage. In animal cells , usually two types of these potentials exist, recognized, for instance, one that is generated via voltage-gated channels, while the other results from voltage-gated calcium channels.

A majority of cells experience a voltage difference between their outside and indoor environment. The voltage of the cell is measured in milli volts (mV). The typical voltage for an animal cell is -70mV. In the majority of cells, no voltage fluctuations are known to be present, however in some cells this can be a normal feature. Some cells show fluctuations in voltage as the voltage goes up and down. The duration of these potentials vary across a range of. In brain cells, the up and down action potential cycle is completed in less than a thousandth of a second. However, in different types of cells, the cycles can take up to a few seconds. The electrical characteristic of an animal cell is dependent on its membrane structure. Cell membranes consist of one layer of lipids along with proteins. The lipid layer functions as an insulation.

Animal cells are all electrically polarized and maintain a voltage difference called membrane potential. For cells, neurons and axons, dendrites and the cell body all have different electrical characteristics. The most stimulated part of a neuron is the axon hillock but axon and cell body too can be stimulated. In the axon hillock, the threshold potential for resting is -70mV and the threshold potential is at -55 mgV. Synaptic stimulation to the neuron cause depolarization, which causes the membrane potential to increase or decrease. It is produced when enough depolarization accumulates and the membrane potential crosses the threshold.

Action potential is the result that voltage-gated ion channels in the plasma membranes of cells. A voltage-gated ion canal is actually a group composed of proteins that remain within the plasma membrane. They produce an action potential in order to cause positive feedback loop. Membrane power is responsible for controlling the condition of ion channels. Action potential is generated as the feedback loop takes place at full intensity. The time and amplitude are determined by the biophysical properties of the voltage-gated ion channels. Different types of ion channels are recognized that create positive feedback cycles and ultimately produce these potentials. Voltage-gated sodium channels play a role in the creation of fast potentials that are similar to nerve impulses. They are slower than those that occur in the muscle cells are mediated by calcium Ion channels.The most studied voltage-gated channel are sodium ion networks that play an important role in the faster conduction of nerve impulses.
