Neurotransmitters Flashcards
Types of neurotransmitters
Acetylcholine Glutamate Aspartate Gamma aminobutyric acid Glycine Norepinephrine Dopamine Serotonin Nitric oxide Carbon monoxide
Acetylcholine
Excitatory/ inhibitory
In parasympathetic system ACH is released at inhibitory synapses
At Neuromuscular junctions ACH is excitatory
Amino acid neurotransmitters
Glutamate
Aspartate
GABA
Glycine
Glutamate and Aspartate have powerful
Excitatory effects
GABA and glycine are important
Inhibitory neurotransmitters
Modified amino acids neurotransmitter
Norepinephrine
Dopamine
Serotonin
Norepinephrine plays roles in
Arousal
Dreaming
Regulating mood
Dopamine are active during what form of responses/behaviors
Emotional responses
Addictive behaviors
Pleasurable experiences
In addition help regulate skeletal muscle tone and some aspect of movement due to contraction of skeletal muscles
Serotonin involved with
Sensory perception Temp regulation Control mood Appetite Onset of sleep
Neurotransmitters consisting of amino acids linked by peptide bonds are called
Neuropeptides
Endorphins are neuropeptides that are the body’s
Natural painkillers
Linked to improved memory, learning, and to feelings of pleasure
Nitric oxide is formed?
On demand
Diffuses out of the cell that produced it and into the neighboring cells and acts immediately
Carbon monoxide is an
Excitatory neurotransmitter produced in the brain and in response to some neuromuscular and neuroglandular functions
Carbon monoxide might protect against and be related too?
Excess neuronal activity
Dilation of blood vessels, memory, olfactory, vision, thermoregulation, insulin release, and anti- inflammatory activity
