Summary Some important histochemical characteristics of the carotid, aortic and coronary glomera have been studied in man and the rabbit. All glomera present a similar histochemical pattern. Type I glomus cells contain acetylcholinesterase, monoamine oxidase and norepinephrine. Type II glomus cells are highly positive for cholinesterase, carbonic anhydrase and nucleoside phosphatases hut they do not contain acetylcholinesterase nor catecholamines. It is postulated that the type I glomus cell is the true chemoreceptor cell. Together with the type II glomus cell, which is considered to be a special type of glial cell, a functional metabolic unit is established. Efferent nerve fibres could be adrenergic; by way of cholinergic transmission action potentials could be initiated in the afferent nerve fibres.
