Why is a chemical synaptic transmission unidirectional?
I’m a really visual person so in order for me to understand concepts with these complexities I gotta go to utube and watch the videos like Neuromuscular junction, action potential, synaptic cleft, or/and neurotransmitters before i can begin to get an understanding. Wikipedia is a pretty good site too because their blue words (if clicked on) are links to further info. There are many different ways to classify neurotransmitters. Dividing them into amino acids, peptides, and monoamines is sufficient for some purposes. Major neurotransmitters: Amino acids: glutamate, aspartate, serine, γ-aminobutyric acid (GABA), glycine Monoamines: dopamine (DA), norepinephrine (noradrenaline; NE, NA), epinephrine (adrenaline), histamine, serotonin (SE, 5-HT), melatonin Others: acetylcholine (ACh), adenosine, anandamide, nitric oxide, etc. In addition, over 50 neuroactive peptides have been found, and new ones are discovered on a regular basis. Many of these are “co-released” along with a small-molecule t
