silver wrote: Normally, sodium voltage gated channels are guarded by calcium in order to repel sodium so that there isn't too much influx of sodium. However, in hypocalcemia, calcium levels decrease in interstitial fluid and blood, so the calcium guarding the sodium voltage gated channels compensate the decreased levels, thereby rendering these sodium volt. gated channels 'unguarded', so there's excessive influx of sodium. action potential is easily produced, because RMP reaches threshold faster and tissue becomes hyperexcitable.
