Where in the brain is the cardiovascular centre for regulating heart rate located? Which of the following set of circumstances would increase the heart rate? Which of the following statements is true?
Understand the Problem
The question is asking about the location of the cardiovascular center in the brain, the circumstances affecting heart rate, and the functions of different nerves related to heart activity. This is related to physiology and the nervous system.
Answer
12. Medulla oblongata. 13. Adrenaline release, physical activity. 14. Sympathetic supply increases rate and force.
- The cardiovascular centre is located in the medulla oblongata. 13. Adrenaline release, physical activity, and fall in blood pressure increase heart rate. 14. The sympathetic supply to the heart increases both the rate and the force of the heartbeat.
Answer for screen readers
- The cardiovascular centre is located in the medulla oblongata. 13. Adrenaline release, physical activity, and fall in blood pressure increase heart rate. 14. The sympathetic supply to the heart increases both the rate and the force of the heartbeat.
More Information
The medulla oblongata plays a critical role in controlling involuntary functions, including heart rate. Adrenaline and physical activity stimulate the heart rate, while the sympathetic nervous system enhances the rate and force of the heartbeat.
Tips
A common mistake is confusing parasympathetic with sympathetic effects on heart rate. Remember, sympathetic activation generally increases heart activity.
