What is wrong about acetylcholine (ACh)
1. Is a cholinergic neurotransmitter
2. ACh has an important role in the enhancement of alertness when we wake up
3. The disease myasthenia gravis occurs when the body inappropriately produces antibodies against acetylcholine nicotinic receptors, and thus inhibits proper acetylcholine signal transmission
