The action potential is a process that causes the membrane potential in a cell is first increased before decreasing. It is a characteristic feature for a range of animal cells , namely muscles, neurons, and Endocrine cells. Plant cells can also produce them. Neurons play the most important function in cell-to-cell communication. In pancreas beta cells, action potentials are connected to it being released by insulin. Plasma membranes are made up of a special kind of voltage-gated ion channel for producing action potential. These channels remain closed in the event that membrane potentials are within that of the cell but if the membrane potential increases then the channels are activated. When they are opened, they permit an inward flow of sodium ions. This in turn increases your membrane's potential. The rapid inward flow of sodium ions changes the membrane's polarity and , consequently, they cease to function. Following this, potassium channels become activated , and it is a flow of potassium ions , causing the membrane is returned to its resting state. A temporary negative shift, known as refractory is a way to stop back forward motion of an action potential. In animal cells typically two types of these potentials are known for example, one of which is because of voltage-gated sodium channels, and one that is produced due to calcium channels that are voltage-gated.

Nearly all cells keep in a voltage differential between their surroundings and their interior. The voltage of a cell is measured in millivolts (mV). The voltage of a typical animal cell is -70 mV. In the majority of cells, little voltage fluctuations are known as occurring, however in certain cells this is an expected characteristic. Certain cells also exhibit variations in the voltage, as they increase and decrease in voltage. The duration of these potentials vary across a range of. In brain cells, the up and down cycles of action potentials are complete in less than the thousandth of a second while in other cells, intervals may be prolonged to several seconds. The electrical activity of an animal cell is dependent on its membrane structure. Cell membrane is comprised of a layer of lipids and proteins. The lipid layer serves as an insulation.

All animal cells are electrically polarized as they maintain the same voltage, also called membrane potential. For neurons, dendrites, axons and cell bodies have different electrical properties. Most excitable portion of an individual neuron is the hillock, but the axon and the cell body can also be excited. The axon hillock's resting potential is -70 mV and the threshold is -55 mV. Synaptic messages to the brain result in depolarization which causes membrane potential to increase or decrease. An action potential is created once enough depolarization has occurred and the membrane potential exceeds the threshold.

Action potential is the outcome of activity of voltage-gated ion channels which are located within the plasma membrane of cells. The voltage-gated ion channel actually a group of proteins that remain embedded inside the plasma membrane. These proteins produce the action potential, which can give rise to positive feedback loop. Membrane potential is responsible for controlling the level of ion channels. Action potential is generated during the time that the feedback cycle continues at its fullest. The duration as well as the magnitude are determined by the bio-physical properties of the ion channels that are voltage-gated. Ion channels of various types are recognized that create positive feedback mechanisms and result in the production of these potentials. The sodium channels with voltage are involved in the generation of larger possibles that resemble those produced by nerve impulse. Lesser ones, such as those created in muscle cells are controlled by calcium Ion channels.The ones that have been the most extensively studied voltage -gated Ion channels are the sodium ion networks that play an important role in higher speed nerve impulse transmission.
