VOCAB QUIZ: Neurotransmitters Flashcards
Released by motor neurons controlling skeletal muscles. It Contributes to the regulation of attention, arousal, and memory.
Acetylcholine (ACh)
Voluntary movement
-Alertness - Attention
-Rewards
-Emotion
Excess - Schizophrenia
Deficiency - Parkinson’s Disease
Dopamine (DA)
-Mood regulation
-Hunger/Appetite
-Sleep
Serotonin
-“Fight or flight” response: elevates heart rate, circulation, respiration; slows digestion
-Controls alertness, arousal
-Mood elevation
Norepinephrine (NE)
Brain’s main inhibitory neurotransmitter
GABA
Brain’s main excitatory neurotransmitter
-Creates links between neurons that form basis of learning, long-term memory.
Glutamate
-Pain control & relief - Stress reduction
-Feelings of pleasure
-Natural opiates
Endorphin
Neurotransmitter associated with Alzheimer’s
Acetylcholine
Depress mood and affect ADHD
norepinephrine (noradrenaline) deficiency
selective serotonin reuptake inhibitors used to combat depression
SSRI’s
Anxiety, OCD, Insomnia, eating disorders
Serotonin excess
Anxiety, High blood pressure
norepinephrine (noradrenaline) excess
Seizures, tremors, insomnia
GABA deficiency
overstimulate brain, migraines or seizures
glutamate excess
excess can lead to insensitivity to pain/little pain
Endorphins
A chemical that mimics the action of a neurotransmitter.
Agonist
A chemical that opposes the action of a neurotransmitter
Antagonist
chemicals released from the terminal buttons of a neuron that excite the next neuron into firing, cause depolarization
Excitatory neurotransmitters
inhibit the next cell from firing
inhibitory neurotransmitters
the neuron that sends a signal across the synaptic cleft
presynaptic neuron
the neuron on the receiving end of the synapse
Postsynaptic neuron
