After the baroreceptor reflex is stimulated,the resulting impulse is transmitted from the carotid artery by which sequence of events?
A) Vagus nerve to the medulla to increase parasympathetic activity and to decrease sympathetic activity
B) Glossopharyngeal cranial nerve through the vagus nerve to the medulla to increase sympathetic activity and to decrease parasympathetic activity
C) Glossopharyngeal cranial nerve through the vagus nerve to the medulla to increase parasympathetic activity and to decrease sympathetic activity
D) Glossopharyngeal cranial nerve through the vagus nerve to the hypothalamus to increase parasympathetic activity and to decrease sympathetic activity

Neural impulses are 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 the heart rate to decrease.This selection is the only option that accurately describes the correct sequence of events asked for in the question.
