neurotransmitters Flashcards
exitatory and inhibitory
glutamate is excitatory, increases possibility of action potential
GABA is inhibitory, decreases possibility of an action potential
neurotransmitter regulation
- receptor (ant)agonist
- inhibitory/enhancement of uptake channels (SSRI)
- inhibition of neurotransmitter synthesis/degradation (MAO)
- direct inhibition/enhancement of ion channels
glutamate
excitatory
GABA
inhibitory
acetylcholine
efferent neurons
dopamine
ascending pathways
reward driven
produced in substantia nigra
noradrenaline
produced in adrenal medulla and postganglionic nerves
released from sympathetic neurons
serotonin
used in antidepressants, antipsychotic, antiemetics and antimigraine drugs
adrenaline
regulating heart rate
tyramine
cannot cross the BBB
octopamine
as sympathomimetic drug
histamine
triggers the inflammatory response
produced by basophils and mast cells
melatonin
secreted into the blood by pineal gland in the brain
