1.3 Neurotransmitters Flashcards
Type of neurotransmission where cells are linked via gap junctions where changes in membrane potential are directly transmitted
Electrical
Type of neurotransmission where neurotransmitters are released by presynaptic neurons to indirectly transmit changes in membrane potential
Chemical
Catalyzes the synthesis of acetyl CoA
Choline acetyltransferase
Ligand-gated ion channel receptor of ACH in the neuromuscular junction
Nicotinic ACh receptor
ACh receptor mediated by G CHON (metabotropic receptor)
Muscarinic ACh receptor
Degradation and uptake of Acetylcholine
Acetylcholinesterase
Precursor of catecholamines
Tyrosine
Process of synthesis of dopa, dopamine, epinephrine and norepinephrine
HydroxylationDecarboxylationHydroxylationMethylation
Storage of catecholamines
VMAT2
Reuptake of dopamine
Dopamine transporter
Reuptake of norepinephrine
Norepinephrine transporter
Degradation of dopamine and norepinpehrine via oxidative deamination
Monoamine Oxidase
degradation of dopamine and norepinephrine via o-methylation
cathecol 0-methyl transferase
Degeneration of dopaminergic neurons in the substantia nigra of the brain
Parkinson’s disease
Autoimmune disease caused by circulating antibodies which break down cholinergic receptors
Myasthenia Gravis
Precursosi of serotonin
Tryptophan
Synthesis of serotonin and melatonin
HydroxylationDecarboxylationAcetylationMethylation
Reuptake of serotonine
Serotonin transporter
Degradation of serotonin
MAO, then oxidation by aldehyde dehydrogenase
Function of glutamate
Excitatory neurotransmitter in the CNS
Inactivation or dgradation of glutamate
taken by glial cells then converted to glutamine
Excitatory neurotransmitter that cannot pass through blood brain barrier
Aspartate
Major inhibitory neurotransmitter in the brainstem and spinal cord
Glycine
Precursor of glycine
Serine
Major inhibitory neurotransmitter in the brain
GABA
Precursor of GABA
Glutamate
Inactivation of GABA
glial cells then converted to glutamate which is then converted to glutamine
