QuestionChoice
This is correct. Baroreceptors are mechanoreceptors located in the aortic arch and carotid sinus which constantly monitor mean arterial blood pressure and pulse pressure. A decrease in arterial pressure results in increased baroreceptor activity, increasing sympathetic activity and thus raising blood pressure.

e
Carotid sinus and vertebral arteries
QuestionChoice
This is incorrect. The baroreceptors responsible for the baroreceptor reflex are located in the carotid sinus and aortic arch. There are baroreceptors located in the atria and pulmonary arteries, however, these are not the arterial baroreceptors.

A 75 year old woman attends her GP surgery with concerns that she sometimes becomes dizzy upon standing. Her blood pressure is measured and found to be 130/95 on sitting but only 105/77 after 3 minutes of standing.

The GP explains that the baroreceptor reflex is one mechanism responsible for limiting the decrease in blood pressure.

In which of the following structures are **arterial** baroreceptors located?
a
