Match each type of membrane potential to its definition: The membrane potential at which voltage gated sodium channels open. The membrane potential that triggers the action potential. Threshold potential Change in membrane potential that may or may not reach threshold and that may be depolarizing or hyperpolarizing. Rapid, strong depolarization followed by immediate repolarization. This potential is self-renewing if the right ion channels are nearby. Answer Options: Resting Potential, Threshold Potential, Graded Potential, Action Potential
An influx of positive sodium ions eventually causes closing of the inactivation gates of voltage regulated sodium channels, stopping the influx of positive sodium ions, and thus the final stages of an action potential are regulated by _____ feedback.

Place the following events in chronological order from 1-8: Nat enters the cell, and depolarization occurs to approximately +30 mV. The voltage across the cell membrane is -70 mV, the resting membrane potential. Upon reaching the peak of the action potential, the VG Nat channels are inactivated by the closing of their inactivation gate and the activation gate of each VG K channel opens. VG K channels close by the closing of their activation gate, and the resting membrane potential is gradually restored. An excitatory post-synaptic potential depolarizes the membrane to threshold and the activation gate of VG Nat channels open. Upon returning to the resting membrane potential, VG Na channels are reset by opening of the inactivation gate and the closing of the activation gate. VG K+ channels are slow to close, resulting in an excess of K* efflux and hyperpolarization. Depolarization occurs as K+ flows out of the cell.
