Q. No.Cardiac activity could be moderated by the autonomic nervous system. Tick the correct answer:
| 1. | The parasympathetic system stimulates heart rate and stroke volume |
| 2. | The sympathetic system stimulates heart rate and stroke volume |
| 3. | The parasympathetic system stimulates heart rate but decreases stroke volume |
| 4. | The sympathetic system stimulates heart rate but decreases stroke volume |
Subtopic: Â Regulation of Cardiac Activity |
 80%
Level 1: 80%+
Hints
The autonomic regulation of cardiac activity is carried out by a neural center located in:
| 1. | Medulla oblongata | 2. | Hypothalamus |
| 3. | Cerebrum | 4. | Thalamus |

Hints
Sympathetic stimulation would lead to:
1. increased heart rate.
2. increased stroke volume.
3. vasoconstriction in visceral blood vessels.
4. all of the above.
