蕈毒碱型乙酰胆碱受器是一大类固定在细胞膜上的乙酰胆碱受器,其对蕈毒碱比对烟碱(尼古丁)更为敏感。反过来对烟碱比较敏感的则称为烟碱型乙酰胆碱受器。蕈毒碱与烟碱两者皆为生物碱(alkaloid)。许多药品与其他类物质(例如pilocarpine与scopolamine)常以促进剂或拮抗剂的角色发生作用,并且其作用是仅单一针对蕈毒碱受器或单一针对烟碱受器,使得这样的受器分类显得有用。

Amanita muscaria from which muscarine was isolated

乙酰胆碱受器中,蕈毒碱受器是一种次分类,广泛分布于中枢神经系统自主神经系统。自主神经系统在解剖上与体神经系统相异。

自主神经系统可分成两个部分, 交感副交感 神经系统

生理学

乙酰胆碱(Acetylcholine, ACh)是一种神经传导物质,在脑部与自主神经系统中广泛存在。
