31. The neurotoxin prevents presynaptic release of acetylcholine from neuromuscular junctions. 32. Its mechanism of action involves blocking the muscarinic acetylcholine receptors. 33. Acetylcholine binds to the receptor on the basolateral membrane of the gland.34. These receptors can bind different ligands like acetylcholine , nicotine and cobratoxin. 35. Muscarinic acetylcholine receptors possess a regulatory effect on dopaminergic neurotransmission. 36. Acetylcholine receptor is a receptor linked to a cation channel.37. There are two ? subunits, with one acetylcholine binding site each. 38. Non-quantal and quantal release of acetylcholine at the neuromuscular junction. 39. RTI-31 also has some muscarinic acetylcholine agonist activity. 40. Dioscorine is a neurotoxin that acts by blocking the nicotinic acetylcholine receptor.
