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

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
