Hyperpolarization In many neurons, the slow voltage-gated potassium channels remain open after the cell has repolarized. Potassium continues to move out of the cell, causing the membrane potential to become more negative than the resting membrane potential. This process is called hyperpolarization. By the end of the hyperpolarization, all the potassium gates are closed. lon Channel Activity During the Action Potential: A Summary During an action potential: Membrane potential (mv) 10. Label the parts of the graph: 30- voltage-gated sodium and potassium channels are closed - Rest voltage-gated sodium channels first open rapidly- Depolarization voltage-gated sodium channels inactivate-Initiation of Repolarization voltage-gated potassium channels open-Repolarization voltage-gated potassium channels close slowly- Hyperpolarization voltage-gated sodium channels reset - Back to rest 70- Time (msec) The Action Potential is Propagated Along the Axon After an action potential is generated at the axon hillock, it is propagated down the axon. Positive charge flows along the axon, depolarizing adjacent areas of membrane, which reach threshold and generate an action potential. The action potential thus moves along the axon as a wave of depolarization traveling away from the cell body. 2 11. Which channel is indicated by the red arrow? . Conduction velocity depends on two things: The diameter of the axon Myelination . ?D
