adrenergicadj.

1934 H. H. Dale in Jrnl. Physiol. 80 Suppl. 11P We seem to need words which will briefly indicate action by two kinds of chemical transmission, due in the one case to some substance like adrenaline, in the other case to a substance like acetylcholine, so that we may distinguish between chemical function and anatomical origin. I suggest the words ‘adrenergic’ and ‘cholinergic’ respectively.
