This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: Cardiovascular system, Subject name: Physiology
Baroreceptor stimulation would result in 
Select and explain. 
A. Decreased Vagal activity, B. Increased Hea rate, C. Decreased sympathetic discharge to hea, D. Increased vasomotor tone
C: Decreased sympathetic discharge to hea
Answer: C: Decreased sympathetic discharge to hea 
Explanation: Baroreceptor stimulation would result in decreased sympathetic discharge to hea.. The baroreceptors are stretch receptors in the walls of the hea and blood vessels. Baroreceptor stimulation, by distension of the structures they are located in, inhibits the tonic discharge of sympathetic nerves and excites the vagal innnervation of the hea. Thus leading to: Vasodilatation and venodilatation Hypotension Bradycardia Decrease in cardiac output Ref: Ganong&;s Review of Medical Physiology 26th edition PGno: 577,578
