Draw a typical action potential using the graph below
properly labeled x- and y-axes
values for resting membrane potential and threshold
the point at which voltage-gated Na+ activation gates open
the point at which voltage-gated Na+ inactivation closes
the point at which voltage-gated K+ channels would normally open and close
the movement of sodium and potassium ions and their direction (into or out of cell)
accurate timing of key events
