PHARM EXAM 1 (MSN) PNS: cholinergic receptors 1. nicotinic (N): all ANS ganglia and medulla 2. nicotinic (M): neuromuscular junction 3. muscarinic: PNS organs site of action: PNS rx -synapse -rx alters synaptic transmission (AcH) SNS: Adrenergic receptors -alpha 1, alpha 2, beta 1, beta 2 -also effects epi/norepi, dopamine breakdown of AcH -via AChE or MAO 1. AcH=reuptake into nerve cell 2. degraded by MAO 3. diffusion of waste out of cell sites where Rx act/influ...

Study Questions and Answers Exam 2 • What are the basic mechanisms by which neuropharmocologic agents act? o Can modify the disease process o Act 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? o Transmitter storage, transmitter release, receptor binding, and termination of the transmission • T...
