quiz 4 (exam 2) Flashcards
potency
= efficacy + affinity
Endocanabinoid Receptor
endogenous ligand of camabinoid receptors
anandamide
endocanabinoid
endogenous substance that binds the cannabinoid receptor molecule
Psilocybin
partial agonist of 5-HT2A Receptors in visual cortex
change in activity of frontal & occipital cortex
Hallucinogen
Ketamine
Block NDMA receptors (antagonist)
stimulate opiod and Ach receptors
help treat depression
Hallucinogen
MDMA
partial agonist of 5-HT2A Receptors in visual Cortex
stimulate release of dopamine
decrease symptoms of PTSD w/ psych therapy
Hallucinogen
LSD `
resembles serotonin
partial agonist of 5-HT2A receptor in visual Cortex
activates DA Receptors
1st generation antipsychotics
block D2 receptors
relieve positive symptoms
2nd generation antipsychotics
relieve negative symptoms
block some serotonin receptors & D2
Benzodiazepines
agonist of GABAa Receptors (inhibitory)
decreases excitability of neurons
xanax and active
anti anxiety drug
Barbiturate
anti anxiety drug
sleep aid
addictive
phenobarbital
Novel Anxiolytics
anti anxiety drug
hormones that interact w GABA receptors
subtle alter antidepressants
Low Ligand Binds to what kind of affinity
high affinity
how strongly receptor binds
Functional Tolerance
up / down regulation
down regulation
decreased number of receptors
after repeated dose of agonist drug
up-regulate
increase number of receptors
repeated dose of antagonist drug
Cocaine
blocks reuptake of & enhances DA & NE transmitters
stimulant
Nicotine
simulates nicotine acetylcholine receptors
agonist on large class of cholinergic receptors
stimulant
Methamphetamine
Reverses the function of DA, SA, NE transporters
results in more DA,SA,NE in the synapse
Ingestion
slow - moderate
inhalation
moderate - fast
peripheral injection
vaccine
moderate - fast
Central Injection
Fast - very fast
Autoreceptor
tells axon terminal how much transmitter has been released
feedback system
presynaptic transmitter release
