Document Summary
Neurotransmitter synthesis: small nts are synthesized at the terminal buttons using enzymes manufactured in the cell body, while larger neurotransmitters (acetylcholine) are synthesized in the cell body by the rough endoplasmic reticulum. Neurotransmitter storage: large neurotransmitters packaged by golgi apparatus and shipped to the vesicles. Smaller nts loaded into vesicles at the terminal buttons. Cholinergic: abbreviated term referring to acetylcholine (parasympathetic nervous system which uses almost exclusively acetylcholine is said to be almost entirely cholinergic) Noradrenergic: areas that produce or are affected by norepinephrine (responsiveness + fear) Glutamatergic: areas that produce or are affected by glutamatergic (key in cellular metabolism) Gabanergic: areas that produce or are affected by gaba. Important stimulators of mood and feelings of well-being. Tyrosine: constituent of most proteins and is important in the synthesis of some hormones. Mesocortical pathway: dopaminergic pathway that connects the ventral tegmentum to the cerebral cortex. Mesolimbic pathway: sometimes referred to as the reward pathway.
