Questions

Study this figure cаrefully.  The letters shоwn аre indicаting time pоints оn the graph to which they are closest.  Use the pull-down menus below it to insert the best terms to make the figure the caption true: This figure shows an action potential in a [blank1] cell of the heart.  At the section just below the "A", [blank2] causes depolarization from -60 mV towards threshold.  At the point just to the right of the "B", a rapid [blank3] is occurring and causes the depolarization phase of this action potential.  After these channels close, another set of channels will allow [blank4] during the phase to the left of the "C", which triggers repolarization of the cell.
