Drag and drop the following events of an action potential into its correct order: Voltage-gated Na+ channels open and Na+ floods into the neuron. Na+ channels inactivate and voltage gated K+ channels open. Ligand-gated Na+ channels open. Voltage gated K+ channels close and membrane potential approaches the resting membrane potential.

Put the steps of action potential into the proper order. Resting membrane potential, voltage gated Na+ and K+ channels open and close, depolarization, hyper-polarization, returns to resting membrane potential.

What is the order of events in an action potential? 1. Stimulus-gated ion channels open, membrane depolarizes slowly. 2. Membrane potential increases to -50 mV. 3. Membrane potential returns to -70 mV. 4. Voltage-gated Na+ channels open, increased permeability to Na+. 5. Voltage-gated K+ channels close. 6. Voltage-gated K+ channels open, increased permeability to K+. 7. Voltage-gated Na+ channels close and deactivate. 8. Voltage-gated K+ channels close. 9. Voltage-gated Na+ channels open, increased permeability to Na+. 10. Membrane potential returns to -70 mV.
Place the following statements in the correct order for an action potential to be generated. 1) A neuron starts at its resting membrane potential 2) Excitatory postsynaptic potentials (EPSPs) are received 3) The cell reaches threshold 4) Voltage-gated Na+ channels open 5) Na+ flows into the cell, making the inside more positive 6) An action potential is generated
