Acetylcholinesterase containing nerve fibres in coronary circulation.
The cholinergic innervation of coronary arteries and veins has been studied in the human. Structures resembling cholinergic nerve fibres are localised at the level of the extraparenchymal branches of the coronary arteries, organised in the adventitial plexus. Neither the coronary veins nor the intraparenchymal blood vessels are provided with a cholinergic innervation. Those findings are discussed.
