NT's Flashcards
Dopamine
Released in the brain’s reward system to reenforce the urge to repeat activity. Too much may be a factor in schizophrenia and too little causes Parkinson’s.
Glutamate
Indirect, Main excitatory NT of the entire CNS and brain. “Brain’s Gas Pedal” and is involved in the formation of memories
Acetylcholine
Primarily direct, excitatory and inhibitory. in CNS, Activates all skeletal muscle fibers, is released by parasympathetic post ganglionic neurons in the PNS, and appears to be the 1st lost in Alzheimer’s disease
Gaba
primary Inhibitory of brain. “Brain’s brakes” NT of the brain. Disruption of its activity is the cause of some epilepsies
Oxytocin
Trust chemical. Role in the brain appears to be concerned with bonding and trusting others
Norepinephrine
Indirect, helps the individual focus on tasks. It also is the flight or fight nt released by sympathetic post ganglionic neurons in the PNS
Serotonin
mostly indirect, Primary NT implicated in mood and mood disorders like clinical depression
Glycine
Inhibitory NT of Spinal Cord
Endocannabinoid
cannabis-like NT affects mood and plays a role in stimulating appetite and in memory.
Endorphin
Opiod like NT, decreases the perception of pain
Substance P
excitatory, released by pain neurons to signal brain about painful stimulus
THC
Tetrahydrocannibinol
What does Tetanus toxin do
Inhibits glycine release, which means glycine cannot inhibit ACh release-which tells muscles to contract, which means muscles won’t stop contracting
epinephrine
indirect, uses G proteins and second messengers, in CNS, brain. excitatory, adrenaline
Agonist:
Activates receptors, same response as normal NT
