NURS 5334 ADVANCED PHARMACOLOGY EXAM 2 STUDY QUESTIONS & ANSWERS LATEST 2021/2022 •What are the basic mechanisms by which neuropharmocologic agents act? oCan modify the disease process oAct at ... the sites of actions which is the axons versus synapses and steps in synaptic transmission and effects of drugs on the steps of synaptic transmission •Transmittter synthesis is the first step in transmission. What are the other 4 steps? oTransmitter storage, transmitter release, receptor binding, and termination of the transmission •True or False: Neuropharmacologic drugs have high selectivity. oTrue—the nervous system uses many different receptor types •Information needed: oType of receptors—through which the drug acts ▪Alpha and beta oNormal responses to the activation of those receptors ▪Agonists vs. antagonists oWhat the drug in questions does to the receptor function •What are the 3 functions of ANS? oRegulates the heart oRegulates the secretory glands, saliva glands, gastric, sweat, and bronchial oIt regulates smooth muscles: bronchi, blood vessels, urogenital system, and the GI tract •What are the regulatory functions of the parasympathetic NS? oSeven regulatory functions ▪Slowing the heart rate ▪Increasing the gastric secretions ▪Emptying the bladder ▪Emptying the bowel ▪Focusing the eye for near vision, ▪Constricting the pupil ▪Contracting the bronchial smooth muscle oIt also regulates the digestion of food, excretion of waste, control of vision and conservation of energy •What are the functions of the sympathetic NS? oRegulation of the cardiovascular system ▪Maintaining blood flow to the brain ▪Redistributing blood and compensating for the loss of blood oRegulation of body temperature ▪Regulates blood flow to the skin ▪Promotes the secretion of sweat ▪Induces piloerection (erection of the hair) oImplementation of the fight or flight reaction ▪Increase HR and BP ▪Blood shuts away from the skin and visera ▪Bronchi dilate [Show More]
