Translations:Acetylcholin-Rezeptor/3/en

The muscarinic M receptor, postsynaptic to parasympathetic nerve endings and in the CNS. When activated by acetylcholine, intracellular messengers (second messengers) are formed. At the heart there is the subtype M2, whose activation by the acetylcholine released by the vagus nerve causes a lowering of the second messenger cAMP (cyclic adenosine monophosphate).
