Myasthenia gravis occurs when this compound's nicotinic receptors are blocked by antibodies; its other receptors are muscarinic.
A receptor for this compound is opposed by a tropane alkaloid that can be extracted from deadly nightshade; that antagonist is called atropine. It binds to either a G-protein coupled receptor or a cys-loop ligand-gated ion channel. Buildup of this molecule can be caused by organophosphate poisoning. This compound originates in the basal optic nucleus of (*) Meynert. Myasthenia gravis occurs when this compound's nicotinic receptors are blocked by antibodies; its other receptors are muscarinic. This compound's transferase is deficient in Alzheimer's disease. The botulinum toxin prevents this neurotransmitter from being released, causing paralysis. For 10 points, name this primary neurotransmitter for motor neurons that is required for muscle contraction.
