Este Cmap, tiene información relacionada con: chardoussin-AP, voltage gated Na+ channels causes influx of Na+ ions into cell, ACTION POTENTIAL IS A ALL OR NONE, RESTING POTENTIAL during resting Voltage gated NA+ channels are closed, DEPOLARIZATION OF CELL Na+ flowing into cell causes membrane potential to be less negative, nerve impulse propagation ???? up one node, influx of Na+ ions opening occurs of voltage sensitive K+ channels, PEAK ???? Na+ channels start to close, REPOLARIZATION is followed by HYPERPOLARIZATION, REPOLARIZATION channels open causing K+ flows out of cell, Na+/K+ Pump provides active transport of ions, EXCITATORY STIMULATION causes opening of voltage gated Na+ channels, More Na+ channels to open causes greater influx of Na+, HYPERPOLARIZATION cell repolarization causes K+ channels to close, HYPERPOLARIZATION cell goes back to RESTING POTENTIAL, PEAK after peak = REPOLARIZATION, greater influx of Na+ membrane potential reaches PEAK, Change in membrane potential during nerve impulse propagation, greater influx of Na+ AKA positive feedback, RESTING POTENTIAL membrane potential -70mV, EXCITATORY STIMULATION causes cell to reach threshold (15mV mem pot) DEPOLARIZATION OF CELL
