name that neurotransmitter Flashcards
a. Released onto organs by the sympathetic nerves
Noradrenalin(NA)or norepinehrine
. LSD and other hallucinogens produce their effects by “messing with”
this NT
Serotonin
Sedatives like alcohol and valium increase its effects
Gaba (It inhibits APs in brain- which suppresses brain function
Low levels can cause clinical depression
Noradrenalin, Dopamine, Serotonin- Any of these this group is know as the monoamines.)
Has excitotoxic effects on neurons—as seen in the brain damage caused
when released in large amounts during a stroke
Glumate
f. Causes the “high” seen with drugs that are stimulants
. Noradrenalin (Stimulants activate the sympathetic nervous system’s release of NA.
A feeling of euphoria–“the high”–along with rapid heart rate, rapid breathing,
and dilated pupils are classic signs of sympathetic nerve action on the body.
Stimulants=cocaine, meth, ecstasy)
g. Low levels cause the uncontrolled muscle tremors of Parkinson’s Disease
dopamine ( it stops skeletal muscle contractions.)
Painkillers like oxycodone and morphine block its release
substance P ( Its sends pain sensations to the brain.)
Especially important in learning and memory formation
Glutamate
Controls the Sleep/Wake Cycle by responding to light
Serotonin
Natural painkillers which inhibit pain sensations
Endorphins/ Enkephalins
Main inhibitory NT used in the brain
Gaba
Major NT which reinforces behaviors by linking them to a pleasure
sensation
Dopamine (Because it links behaviors to pleasure, it is the main NT responsible for drug
addiction.)
Dissociative anesthetics block its receptors in the brain, causing
the mind to feel “disconnected” from the body
Glutamate (Ketamine & PCP keep it from binding to its receptors. This numbs all body
sensations and reduces pain.)
Opioid painkillers act like this NT by using its receptors, making them
much more effective and addictive than aspirin as painkillers
Endorphins/Enkephalins (Opioids like heroin, morphine & oxycodone act like these NTs,
which means they activate the body’s natural painkilling system.)
