The correct sequence of events that occur after the baroreceptor reflex is stimulated is that the impulse is transmitted from the carotid artery to the:
A)vagus nerve to the medulla to increase parasympathetic activity and decrease sympathetic activity.
B)glossopharyngeal cranial nerve through the vagus nerve to the medulla to increase sympathetic activity and decrease parasympathetic activity.
C)glossopharyngeal cranial nerve through the vagus nerve to the medulla to increase parasympathetic activity and decrease sympathetic activity.
D)glossopharyngeal cranial nerve through the vagus nerve to the hypothalamus to increase parasympathetic activity and decrease sympathetic activity.

Neural impulses are then transmitted over the glossopharyngeal nerve (ninth cranial nerve) from the carotid artery and through the vagus nerve from the aorta to the cardiovascular control centers in the medulla. These centers initiate an increase in parasympathetic activity and a decrease in sympathetic activity, causing blood vessels to dilate and heart rate to decrease.
