Cardiac Perfusion Practice exam with real and latest updated solutions 2024 Which of the following stimulates the heart muscle to contract? Electricity Negatively Depolarization Contraction Repolarization - correct answer.Electricity The internal cell is _________________ charged at rest. Cell-to-cell Sequentially Relaxation Negatively Depolarization - correct answer.Negatively V tach - correct answer. A fibrillation - correct answer. Stimulating the change of the cell's internal and external polarity is called ____________. Repolarization Depolarization Relaxation Sequentially Cell-to-cell - correct answer.Depolarization Depolarization produces __________________ of the muscle. Contraction Repolarization Depolarization Relaxation Electricity - correct action Contraction is the return of the internal cell negative polarity and muscle repolarization. True False - correct Depolarization and repolarization occur _______________. Depolarization Repolarization Sequentially Cell-to-cell Electricity - correct answer.Sequentially These processes proceed through __________ communication and high speed tracts. Relaxation Cell-to-cell Depolarization Repolarization Negatively - correct answer.Cell-to-cell Depolarization and repolarization involves the exchange movement of Sodium and Potassium across the cell wall with calcium modulation. True False - correct The exchange movement of sodium and potassium across the cell wall (with calcium modulation) sets the rate of the electrical spread and muscle contration. True False - correct Which of the following reflects the ability to start the depolarization process. Excitability Automaticity Autonomic nervous system Conductivity Contractility - correct acity Which of the following is a measure of the cell's ability to contract? Autonomic nervous system Contractility Automaticity Excitability - correct actility Which of the following is the cell's responsiveness to an electric stimulus? Conductivity Contractility Excitability Autonomic nervous system - correct ability Which of the following is the abilty of the cell to transmit a stimulus to another cell? Contractility Automaticity
