_______________ is the study of drugs that alter processes controlled by the nervous system.
|
neuropharmacology
|
|
|
Name the 2 categories of neuropharmacologic drugs.
|
peripheral nervous system (PNS) drugs and central nervous system (CNS) drugs
|
|
|
T or F. Most drugs target axonal conduction?
|
F. Most drugs target synaptic transmission.
Drugs that target axonal conduction are not selective. |
|
|
List the 5 steps of synaptic transmission.
|
1.) Transmitter synthesis
2.) Transmitter storage 3.) Transmitter release 4.) Receptor binding 5.) Termination of transmission |
|
|
Axonal Conduction
|
Movement of an action potential down the axon.
|
|
|
Synaptic Transmission
|
Information carried across the neuron gap and the postsynaptic cell.
|
|
|
What we need to know about PNS drugs.
|
1.) Type of receptor through which the drug acts (alpha1, alpha2, beta1, etc)
2.) Normal response to activation of those receptors (agonist versus antagonist) 3.) What the drug in question does to receptor function |
|
|
What are the two ways drugs affect receptor function?
|
They can either increase or decrease receptor activation.
|
|
|
____________ _______________is defined as an effect on receptor function equivalent to that produced by the natural transmitter at a particular synapse.
|
receptor activation
