Lego Crazy Action Contraptions. One thing that really bothered me when i starting building lego technic models is the lack of bricks and beams. There are now 263,508 members.

It is an event in which the potential of the membrane in a cell is first increased and then decreases. It is a signature characteristic of a number of cell types in animals, such as muscles, neurons and the endocrine cells. Certain plant cells also produce these. Neurons play an extremely important part in cell-to cell communication. in pancreas beta cell actions potential is associated with that release of insulin. Plasma membrane has special type in voltage-gated, ion-channels that are used for producing action potential. These channels are shut once the membrane's voltage is within the resting potential of the cell . However, if the membrane potential increases and the channels begin to open, they become active. If the channels are open, they allow for an inward flow sodium ions. This in turn increases the potential of membranes. The rapid flow of sodium ions results in changing the membrane's polarity and in turn, they become inactive. The potassium channels, after which, become activated and you can see an outward movement potassium ions . Upon this, the membrane returns to its normal state. A transient , negative shift known as refractory duration prevents the reverse traveling of the action voltage. In animal cells generally , two kinds of these are identified, for instance, one which is triggered due to the voltage-gated sodium channels and the other which is produced due to voltage-gated calcium channels.

Nearly all cells maintain an electrical difference between their exterior and interior environments. The cell's voltage is measured in milli volts (mV). The typical voltage for an animal cell is around -70 mV. The majority of cells show tiny voltage fluctuations are observed to be present, however in some cells, this is a standard characteristic. Some cells also show the cycle of up and down as the voltage goes up and down. The duration of these voltages are variable across a variety of. In brain cells the down and up phase of an action potential are completed in a fraction of a millisecond of a second. In other cell types, the cycles can take up to a few seconds. The electrical property of an animal cell is dependent on the membrane structure. The cell membrane is composed of one layer of lipids along with proteins. The lipid layer serves as an insulation.

Animal cells are all electrically polarized and maintain an electric voltage which is known as membrane potential. In case of neurons, , dendrites and the cell body possess different electrical characteristics. The area that is most excitable in neuron is the axon hillock. However, the axon, dendrites, and cell body too can be stimulated. At the axon , the resting potential is 70 mV and the threshold potential is -55 MV. Synaptic stimulation to the neuron result in depolarization causing the membrane potential to increase or fall. An action potential is created once enough depolarization accumulates and the membrane potential reaches a threshold value.

Action potential is the result of the work of voltage-gated Ion channels located in the plasma membrane of cells. The voltage-gated channel is actually a cluster of proteins that are embedded inside the plasma membrane. These proteins produce motion potential because it can create positive feedback loop. Membrane current is responsible controlling the level of Ion channels. Action potential is generated when the feedback cycle takes place at full intensity. Its duration and amplitude are determined by the bio-physical properties of the voltage-gated ionchannels. Many kinds of ionchannels are known to produce positive feedback and result in the production of these potentials. Voltage-gated sodium channel are involved in the generation of higher-frequency impulses like nerve impulses. Slower ones , like those made in the muscle cells are controlled by calcium ion channels.The ones that have been the most extensively studied voltage -gated channel are sodium ion channel that participate in faster nerve impulse conduction.
