Across
- 2. One complete contraction and relaxation of all 4 heart chambers
- 6. heart cells
- 8. Contraction in the Heart
- 9. linkages that prevent the contracting cardiomyocytes from separating
- 10. increase in membrane potential
- 11. connections between cardiomyocytes
Down
- 1. decrease in membrane potential
- 3. Relaxation in the Heart
- 4. a signal originates in the heart itself Myogenic
- 5. does not rely on nervous system for its rhythm
- 7. Protein found in muscles that stores oxygen
