Muscarinic receptor
From Pharmpedia
Muscarinic receptors are those membrane bound acetylcholine receptors that are more sensitive to muscarine than to nicotine. Those for which the contrary is true are known as nicotinic acetylcholine receptors. Muscarine and nicotine are both alkaloids. Many drugs and other substances (for example atropine and scopolamine) act as agonists or antagonists of only muscarinic or only nicotinic receptors, making this distinction useful.
