Exam 1 - Chapter 3 Flashcards
What drugs mimic the effects of neurotransmitters naturally found in the human brain by binding to and stimulating the receptor cite?
Agonist (Contender)
What drugs block the neurotransmitters thereby obstructing the neurotransmitters action?
Antagonist (Opponent)
What do neurons do?
- Respond to stimuli
- Conduct electrical impulses
- Release chemicals (neurotransmitters)
Presynaptic neuron –> synapse –> ?
Postsynaptic neuron
What is a chemical substance that functions as a neurological messenger?
neurotransmitter
What are the types of neurotransmitters?
- Norepinephrine
- Serotonin
- Dopamine
- Glutamate

What is pharmacodynamics?
- What drugs do and how they do it
- Drug action and drug response
What is pharmacokinetics? (hint ADME)
- Absorption
- Distribution
- Metabolism
- Excretion
What is pharmacogenetics?
Effects of genetic variation on drug expression
What are located on the neuron surface?
Receptors
A junction between two nerve cells consisting of a minute gap across which impulses pass by diffusion of a neurotransmitter is what?
Synapses
When neurotransmitters are taken back into presynaptic cell by which they were originally released is called what?
Cellular Re-uptake (either reused or destroyed)
Why do MAOIs and TCAs need to be prescribed with caution?
?
