Document Summary
N3111 exam #2 study guide spring 2016. Steps of synaptic transmission: transmitter synthesis a. What are the effects of drugs on each step: selective serotonin reuptake inhibitors (ssris) Work on step 5 by blocking the reuptake of the transmitter, which in returns makes more of the transmitter present in the synaptic gap increasing the likelihood of the neurotransmitter binding to a receptor: naloxone (narcan) Works on step 4 by competing for the receptor sites and blocking other agents to bind. Being specific to the receptor: causes the drug to only have the adverse effects associated with that receptor. Having effects on multiple receptors: causes a drug to have all the good effects as well as the bad ones. Chapter 13 physiology of the peripheral nervous system. Alpha 1: location: eye, arterioles/veins, male sex organs, prostatic capsule, bladder, activated (agonist drugs) Mydriasis (pupil dilation)- constriction of radial muscle. Constriction of the trigone and sphincter of bladder: blocked (antagonist drugs)
