Question

Where are the sensors for the arterial baroreceptor reflex located? View Available Hint(s) Where are the sensors for the arterial baroreceptor reflex located?
A) carotid sinus and aortic arch
B) cardiovascular centers in the medulla oblongata
C) The sympathetic and parasympathetic nervous systems

Answer 1

Answer:

The correct answer is option A, that is, carotid sinus and aortic arch.  

Explanation:

The baroreceptor reflex or the baroreflex is one of the homeostatic mechanisms of the body, which assists in maintaining blood pressure at almost the same levels. They are stretch receptors and reacts towards the pressure stimulated broadening of the blood vessel in which they are located. These receptors function via negative feedback systems involving pressure sensors, which sense the arterial pressure. The most essential arterial baroreceptors are situated in the aortic arch and in the carotid sinus.
