Acetylcholine
Synthesized from choline and acetyl-CoA
Synthesis takes place mainly in terminals of axon
Nitric oxide by product of conversion of amino acid arginine to citrulline, as gas can pass through any membrane and thus cannot be stored
Carbon monoxide split from heme by heme oxygenase, present in hippocampus and olfactory bulb
Neurotransmitters nervous system
Why so many?
The response of a neuron to a neurotransmitter determined by the receptor to which transmitter binds, therefore no obvious functional explanation for why so many needed
· explanation may be evolutionary, brain evolved by random variation and natural selection, mutations in membrane proteins may have yeilded molecules that respond to various chemical substances that nerves happen to release, particular neurotransmitter systems evolved because different chemicals happened to best serve neurons that had specific functions
Neurotransmitters have specific
