Answer-norepinephrine, epinephrine, & dopamine
What are the types of adrenergic receptors?? Correct Answer-A1 (all
smooth muscle, glands and organs) and B1 (heart, juxtaglomerular cells,
kidneys) = Stimulate

bronchioles)), glands, and organs) = Suppress

What is the pathophysiology of sympathetic nervous system? Correct
Answer-Physiological changes induced by the sympathetic nervous
system include accelerating the heart rate, widening bronchial passages,
decreasing motility of the large intestine, dilating the pupils, and causing

HR and contraction force; release of renin (B1); inhibition of smooth
muscle (B2); lipolysis/relax detrusor muscle to pee (B3/Bruno)
