Q.

What are statins?

Q. The purpose of the AV node is to _______ and the purpose of the Purkinje fibers is to _______.

1. create simultaneous atrial and ventricular depolarization; speed up transmission of the cardiac impulse into the ventricle
2. delay ventricular depolarization relative to atrial depolarization; insulate the cardiac impulse from the general ventricular fibers
3. delay ventricular depolarization relative to atrial depolarization; transmit the cardiac impulse to very small localized groups of ventricular fibers
4. delay atrial depolarization relative to ventricular depolarization; transmit the cardiac impulse to very small localized groups of ventricular fibers

Q. Which of the following events does not take place during a ventricular systole

iii. During the start of the ventricular systole the bicuspid and tricuspid valves close
iv. Due to the closure of the atrio-ventricular valves, dup sound is produced.

2. Event 2, 3 does not take place
3. Event 1, 4 does not take place
4. All events take place
