EXERCISE 6: CARDIOVASCULAR PHYSIOLOGY

|ACTIVITY 1: Investigating the Refractory Period of |Answers |
|Cardiac Muscle | |
|Which of the following types of muscle tissue can depolarize spontaneously in the |C- Cardiac Muscle |
|absence of any external stimulation: | |
|Skeletal muscle | |
|Smooth muscle | |
|Cardiac muscle | |
|All of the above | |
|Look at Figure 6.1, the cardiac action potential. The period of time between the |Absolute refractory period of cardiac muscle |
|beginning of the cardiac action potential and the approximate middle of phase 3 is | |
|the __________________ refractory period of cardiac muscle. | |
|In this simulation, when you
