B)arteries entering the neck region
C)arteries leaving the heart
D)cells in the brain,arteries entering the neck region,and arteries leaving the heart
E)arteries entering the neck region and arteries leaving the heart

Question

Quizplus · Accepted Answer

Baroreceptors are located in the carotid sinus and aortic arch, which are the areas where the arteries enter the neck region and leave the heart respectively. These locations allow the baroreceptors to detect changes in blood pressure and send signals to the brain to help regulate circulation. While baroreceptors have connections to the brain, they themselves are not located in the brain. Therefore, the correct answer is arteries entering the neck region and arteries leaving the heart.
