Drugs and NRTMs Flashcards
1
Q
Heroin
A
- Normal: inhibitory NRTMs active in synapse stop domamine from being released
- Heroin stops inhibitory NRTM from being released and dopamine is let free
- Heroin mimics Opiate (natural)
1
Q
Marijuana
A
- Normal: inhibitory NRTMs active in synapse stop domamine from being released
- cannabinoid receptors blocked by THC which turns off inhibitory NRTM so dopanie released
- THC mimics anandamide
2
Q
LSD
A
- LSD enters into synapse and takes up seratonin receptors
- LSD can excite or inhibit cell it attatches to through receptor
- LSD mimics seratonin
3
Q
Alcohol
A
- Normal: GABA inhibits action potentials while GLUTAMATE excites action potentials to control neural activity
- alcohol interacts with both GABA and GLUTAMATE receptors
- makes GABA more inhibitory and GLUTAMATE inhibitory
4
Q
Ecstasy
A
- Normal: seratonin transporters remove SRTN from cleft after its done its job
- ecstasy is taken up by transporters instead of the SRTN
- seratonin continues to bind with receptor (overstimulation)
- ecstasy mimics seratonin
5
Q
Cocaine
A
Normal: dopamine transporters remove dop from cleft after job done
- cocain blocks transporters so dop trapped in cleft (overstimulation)
6
Q
Methamphetamine
A
- Normal: dopamine transporters remove dop from cleft after job done
- Transporters take meth instead of dop
- dop stuck in synapse, binds again and again, overstim
- meth mimics dopamine
