Term
cholinergic neurotransmission
Definition
Acetyl CoA plus choline becomes acetylcholine by ChAT. Acetylcholine then gets stored in a storage vesicle by VAT. With calcium influx, an action potential causes the release of acetylcholine so that it can bind onto the different cholinergic receptors. Then acetylcholinesterase breaks down acetylcholine to choline and acetate or acetic acid
Term
adrenergic neurotransmission
Definition
Tyrosine ultimately gets converted to dopamine through two different enzymes-- tyrosine hydroxylase and then dopa decarboxylase. Dopamine gets converted to norepi by dopamine beta-hydroxylase and then to epinephrine by phenylethanolamine and methyltransferase.
Dopamine, norepi, and epi are your three most common adrenergic neurotransmitters. Of these three, norepinephrine is the primary one. These neurotransmitters get brought up to a storage vesicle by a transfer known as VMAT. Once in the storage vesicle, calcium influx then causes the release of these neurotransmitters, which then can bond onto different adrenergic receptors. Ultimately, dopamine, norepi, and epi-- their action is reduced or stopped two ways. One of them is by a transport known as NET, which actually brings these neurotransmitters back to the cytoplasm, which is highlighted in step three of this transmission process. So that's one way in which dopamine, norepi, and epi actions just reduce or stop.
Another way, if you see what's bold at the bottom of your screen, is that these three known transmitters can be inactivated by two enzymes. One of them is known as COMT, which is the abbreviation for catechol-o-methyltransferase, and then another one is by MAO, your monoamine oxidase
