|
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 |
