Question 1

The importance of the plateau phase of the action potential of myocardial cells is in
◦ preventing tetanus.
◦ regulating Ca2+ availability to the cells.
◦ preventing overstretching of the cells.
◦ enhancing the efficiency of oxygen use by the cells.
◦ preventing fibrillation.

Question 2

Autorhythmic cells can generate action potentials spontaneously because they have
◦ L-type Ca2+ channels.
