Quiz 2- Neurotransmitter Systems/Oligodendrocytes

Immunocytochemistry

using anitbodies to label proteins and visualize

Immunohistochemistry

using antibodies to label proteins in tissues/ brain slice

in situ hybridization

using complimentary nucleic acids to bind and tag mRNA

autoreceptors

neurotransmitters present on the presynaptic neuron. regulate activity

Cholinergic neurons

Acetyl CoA and Choline and made into acetylcholine by ChAT enzyme —>ACH is transported and released by vesicle —> ACHe breaks it down into choline and acetic acid

Catecholaminergic

makes dopamine, norepinepherine, or epinepherine. Tyrosine →DOPA →Dopamine→Norepinepherine→Epinepherine. MAO degrades

Serotonergic Neurons

Tryptophan (diet) precursor of serotonin. SSRIs prevent reuptake of serotonin. Degraded by MAO

Amino Acidergic Neurons

Glutamate(excitatory), GABA, Glycine(inhibitory). EAAT take glutamate from synaptic cleft.

Endocannabinoid

Oligodendrocytes

create mylelin

Astrocytes

surround the synaptic gap and release gliotransmitters. Water transport across brain. Maintain blood brain barrier.

Microglia

resident immune cells. macrophages, eat nulclei
