  • The impulses from the aorta and carotid sinus are involved in regulating and maintaining blood pressure. When the blood pressure in these areas increases, specialized nerve receptors called baroreceptors detect the change and send signals to the brain. In response, the brain sends impulses to the heart to decrease its rate, resulting in a decrease in heart rate. This mechanism helps to regulate blood pressure and maintain homeostasis.Hence, option 1 is the correct answer. 

Explanation for the incorrect options :

  • Option 2 is incorrect because it increases the heart rate. o
  • Option 3 is incorrect because it initially increases and then decreases the heart rate.
  • Option 4 is incorrect because it shows no change in heart rate.
