I know this is picky..but it's bothering me. Can anyone clarify if enterochromaffin cells have M1 or M3 receptors? FA says M1 but Wiki sorta says M3.

well I know that the ECL cells are stimulated by the enteric nervous system by M1


Parietal cells are stimulated directly by M3.


Moreover, first aid also indirectly mentions this through discussion of propantheline and piperizine.

Sounds good. That's actually the page I was studying. A pic in Wiki said otherwise but I think I'll go with what you said. Thanks!
