Interiors of heart muscle cells are:

Negative at rest (polarized)

When depolarized, the interiors become:

Positive and myocytes contract.

The cell to cell conduction of depolarization through the myocardium is initiated by:

Fast moving sodium Na+ ions

The electrical conduction pathway between the atria and the ventricles?

AV Node

Depolarization conducts slowly through the AV node since it is carried by:

Ca+ ions

For the conduction of depolarization, purkinje fibers use:

Fast moving Na+ ions

Repolarization is accomplished by:

Potassium K+ ions leaving the myocytes.

Cause myocyte contraction:

Calcium Ca++ ions

Outflow causes repolarization of myocytes:

Potassium K+ ions

Movement produces cell-to-cell conduction of depolarization of the heart:

Sodium Na+ ions
