Þýðing á "rising phase" í íslenska

what ion occurs in the rising phase of the action potential? Inward Na+. During the rising phase of the action potential, the following occurs: Voltage-gated sodium (Na+) channels open: Depolarization of the membrane potential to the threshold triggers the opening of these channels. This allows a rapid influx of Na+ ions into the neuron, making the inside of the membrane more positive relative to the outside. Driving force for Na+: Both the electrochemical gradient (high Na+ concentration outside the cell and negative resting membrane potential) drive Na+ ions into the cell. Result: This rapid inward movement of Na+ causes the sharp depolarization characteristic of the rising phase of the action potential. The rising phase is critical for initiating the electrical signal that will travel down the axon to communicate with other neurons or target cells. [..]
