The action potential Retin-a generic Action potential (AP) occurs in the membranes of excitable cells under the influence of the stimulus threshold or subthreshold values ??which increases the permeability of the membrane to sodium ions. The sodium ions begin to enter into the cell, resulting in a decrease in membrane potential - membrane depolarization. With decreasing magnetic field to a critical level of depolarization opens voltage-gated sodium channels and membrane permeability for these ions increases 500raz (exceeding the permeability to potassium ions in the 20 times). As a result, the penetration of sodium ions in the cytoplasm and their interaction with the anions on the membrane potential difference disappears, and then there is recharge of the cell membrane (the inversion charge overshoot) - inner membrane surface becomes positively charged relative to the exterior (30 - 50 mV), then closed sodium channels and voltage-gated potassium channels open. As a result, the output of potassium from the cells begin the process of restoring the original level of the resting membrane potential - the membrane repolarization. If xenical generic such an increase in conductivity to prevent the introduction of potassium tetraethylammonium, which selectively blocks the potassium channels of the membrane repolyarizuetsya much slower. Sodium channels can be blocked by tetrodotoxin and unlock the subsequent introduction of the enzyme pronase, which breaks down proteins.
